Some Insights About The Robotics Industry

Mobility is a new promise in flexible robotics. While fixed robots will always have a place in production, augmenting traditional robots with mobile ones promise more flexibility to end-users in new applications. These applications could be for medical and surgical uses, personal assistance, security, warehouse and distribution applications, and ocean and space explorations as well.

Mobile Apps


Mobile robots are growing says Rush LaSelle, VP and General Manager with Adept Technology Inc. (Pleasanton, California).

Lowered costs enable deploying both large and small fleets of vehicles in warehouse distribution and line-side logistics usage.

Mobile robots could be particularly useful in painting and de-painting applications.

Medical/Surgical Applications


There is a potential use of mobile robotics in medical and other life sciences applications. Medical application is a growing field with huge untapped applications like drug delivery, or the development of mobile systems for specialized equipment.

Autonomous mobile robots (AMR) could play a role in assisting doctors in surgical procedures. AMR technology is applied in surgical applications. Based on inputs, the robot’s arm assists the surgeon to perform a task. Path-planned algorithms move the robot autonomously.

Danger Seeker


Mobile robots can access those areas which are dangerous to humans. Mobile robots are used to reach inaccessible areas like nuclear power plants. Mobile robotics is very useful in nuclear environments with high levels of radiation, mainly during a disaster or threat of a disaster.

Mobility=Lean

The vision of a lean manufacturing is being realized through mobile robotics. Mobile robotics connects islands of automation. Mobile robots are now used for transporting materials from donation areas and taking these raw materials to a work cell.

LaSelle thinks mobile robotics serving the ends of lean manufacturing through processing of optimal batch sizes in warehouse and palletizing applications.

Companies look for solutions to choose cases or parts within a warehouse as compared to pull a full rack. As this trend continues, expect to see more demand for systems encompassing mobility, manipulation, and vision. Given the rate of technological developments and drive for smaller batch sizes in manufacturing, you could see mobile robots becoming a staple in a large cross section of manufacturing within the next 6 to 7 years.

Autonomous Locomotion

Genuine independent mobility is necessary for robotics to add significant value to manufacturing.Mobility moves robots from being machines to production partners. The robot has to move to the work but if the robot is bolted to the floor and has no work before that robot, the robot is adding zero value to the production process. Bringing a mobile robot to where production is rather than bringing production to a fixed robot is the philosophical underpinning of mobile robotics.

Going Mobile


Like many, cutting-edge technology, mobile robotics has yet to become the norm in manufacturing. In heavy or unusual payload applications, mobile robotic platforms are becoming increasingly common along with a great deal of interest in small mobile platforms. Given the current level of technology already used in mobile platforms, these products would likely become very common within the next five to 10 years.

To achieve the goal, the robotics sector will need to continue educating end-users on the power of mobile robotics.

We conclude now.

Automotive engineers and the automotive mechanics, both play critical roles in keeping safe and efficient vehicles on the roads. Engineers work on vehicles on a broader aspect, they design and develop new vehicles and improve the performance of existing machines. Mechanics find out and repair vehicles on a case basis, mainly in a repair shop or at the shops of an auto dealer.

Responsibilities Of An Auto Engineer

Along with working for auto manufacturing companies, automotive engineers also does work for engineering firms, government regulatory agencies and other departments and firms that require vehicle engineering expertis. Some engineers work on the creation of automobiles, helping to design systems and components, while others examine existing vehicles to analyze their effectiveness and to diagnose systemic problems and explore possible improvements. Engineers are an essential part of the manufacturing of vehicles and the ongoing oversight that ensures their fitness for public usage.

Responsibilities Of An Auto Mechanic

Auto mechanics mainly work in auto repair shops, either a shop that repairs vehicles or a dealer that works for a particular brand. Mechanics work directly with drivers but engineers do not, they discuss the specific operations of a particular vehicle. Mechanics labour to find the source of problems, next repair them so the vehicle can operate near to its optimum level. Mechanics carry out routine inspections of vehicles to ensure that they are safe to operate on the road.

Education and Training

Automotive engineers need a minimum of a bachelor’s degree in engineering and many goes ahead to earn a master’s degree that helps them to specialize on specific areas of automotive engineering. Auto mechanics can do with a minimum of high school degree or its equivalent. In addition, mechanics receive extensive training before they work on vehicles. Some mechanics start training at a vocational school or in someone’s degree program that is carried out mainly on automotive repairs.

An Overview Of Machine And Its Types

Machine design is an important part for engineering applications. But what is a machine? Machine is a devise that comprises of the stationary parts and mobile parts combined together to produce, transform or use mechanical energy. Some types of machines are: lathe, engine, compressor and many more.

A Machine design is an important part of engineering use. All the machines are made up of elements or parts or units. Each element is a separate part of the machine and it might have to be designed separately and in assembly. Each element in turn can be a complete part or made up of several small pieces which are joined together. Several machine parts are joined together to form a complete machine.

Here we list some examples of machines:

1) Lathe: It uses mechanical energy to cut the metals.

2) Turbines: They yield mechanical energy.

3) Compressors: They compress the air.

4) Engines: They consume fuel to produce mechanical energy.

5) Refrigerators and air-conditioners: They yield cooling effect.

6) Washing machines: They use mechanical energy to wash clothes.

Classification of Machines

Based on various applications, machines are classified into three main types:

1) Machines producing mechanical energy: These machines are also called prime movers. These machines convert some form of energy like heat, hydraulic, electrical, etc into mechanical work. The most popular of these machines is the internal combustion engine in which the chemical energy of fuel is converted into heat energy which is again converted into mechanical work in the form of rotation of vehicle wheels.

2) Machines transforming mechanical energy: These machines are also called converting machines as they convert mechanical energy into other forms of energy like electricity, hydraulic energy etc. Some examples are electric generator in which the shaft rotates to convert into electrical energy, and hydraulic pump in which the rotation energy of the rotors is converted into the hydraulic energy of the fluid.

3) Machines utilizing mechanical energy: These machines receive mechanical energy and use it for several applications. An example of these machines is lathe machine that utilizes the mechanical energy to cut metals and washing machine that utilizes the rotation of the rotor for washing the clothes.

We conclude here.

In order to get highly efficient in the process and implement of high level design process, mechanical designers and engineers must have good grasp on their conceptual and practical knowledge of the software through our quality and comprehensive CAD/CAM courses.

An Introduction To Hydraulics

Hydraulics is a branch of science that deals with the practical applications of fluids, mainly liquids, in motion. It is related to fluid mechanics, which mostly provides its theoretical foundation. Hydraulics deals with matters as flow of liquids in pipes, rivers, and channels and their confinement by dams and tanks. Some of its principles are applied to gases as well, mainly in cases in which variations in density are comparatively small. The scope of hydraulics extends to mechanical devices like fans and gas turbines and to pneumatic control systems.

Liquids in motion or under pressure did useful work for mankind for many centuries before French scientist-philosopher Blaise Pascal and Swiss physicist Daniel Bernoulli formulated the laws on which modern hydraulic-power technology is based. Pascal’s law states that pressure in a liquid is transmitted equally in all directions. In the hydraulic press, Pascal’s law is used to increase force.

Bernoulli’s law states that energy in a fluid is due to elevation, motion, and pressure, and if there are no loss due to friction and no work is done, the sum of the energies remains constant.

Until 19th century it was impossible to develop velocities and pressures much greater than those provided by nature, but the invention of pumps brought a vast power for application of the discoveries of Pascal and Bernoulli. In 1882 the city of London built a hydraulic system that delivered pressurized water through street mains to drive machinery in factories.

In hydraulic-power systems there are 5 elements: the driving force, the pump, the control valves, the motor, and the load. The driver might be an electric motor or any engine.The pump acts mainly to increase pressure. The motor might be a counterpart of the pump, transforms hydraulic input into mechanical output. Motors might produce either rotary or reciprocating motion in the load.

The growth of fluid-power technology since World War II has been amazing. In the operation and control of machine tools, farm machinery, construction machinery, and mining machinery, fluid power can compete successfully with mechanical and electrical systems. Its chief benefits are flexibility and the ability to multiply forces efficiently; it also provides fast and accurate response to controls. Fluid power can offer a force of a few ounces or one of thousands of tons.

Hydraulic-power systems have become a major energy-transmission technologies used by all phases of industrial, agricultural, and defense activity.

Electromagnetic Clutch: Working, Use, Advantages and Limitations

The operating principle of an actuator of electromagnetic clutch is an electromagnetic effect, but torque transmission is mechanical. The difference between electromagnetic clutch and the regular clutch is the way they control the movement of pressure plates. In a normal clutch, a spring used to engage the clutch whereas in EM clutch an electromagnetic field is used for engagement.

The electromagnetic clutch comes in various forms, including magnetic particle clutch and multi-disc clutch. There are even no-contact clutches like hysteresis clutch and eddy current clutch. But the most widely used form is a single face friction clutch.

Working Methods

The main components of EM clutch are a coil shell, an armature, rotor, and hub. The armature plate is done with friction coating. The coil is placed behind the rotor. When the clutch is activated the electric circuit passes energy to the coil, and thus generated a magnetic field. The rotor portion of clutch gets magnetized. When the magnetic field exceeds the air gap between rotor and armature and then it pulls the armature toward the rotor. The frictional force produced at the contact surface transfers the torque. Time of engagement depends on the strength of magnetic fields, inertia, and air gap.
When voltage is removed from the coil, the contact is over. In most design a spring is used to hold back the armature to provide an air gap when current is removed.

Applications

They could be used for remote applications as they do not need linkage to actuate the clutch. They are used in printing machinery, conveyor drives, copier machines and factory automation. In an automobile, it replaces clutch pedal with a switch button. A smaller EM clutch is used to drive the compressor of air conditioning system.

Benefits and limitations of electromagnetic clutch

Benefits
  • The complicated linkage is not needed to control the clutch.

Limitations

  • High initial costing.
  • Operating temperature is limited because at high-temperature insulation gets damaged.
  • The risks of overheating during engagement.
  • The brushes to energize coils need a periodic check.

We conclude now.

If you are looking for CAD CAM certification course in Pune and want to do AutoCAD training courses, then do consider CRB Tech Solutions for its big name in this field. We will help and support you in enhancing your skill in AutoCAD programs and grow in this field.

We also offer mechanical design engineer courses with a well structured program in view of offering CAD CAM training to mechanical engineering students.

Unconventional Manufacturing Process

In the last two decades some hard and difficult to process metals and alloys were not easy to produce, but continuous research on this field would produce fast growth in this modern machining technology.

The concept of material removal by traditional edged tool machining is uneconomical and the degree of accuracy and surface finish is poorly attainable. These edged tools machining involve plastic deformation and formation of chips has been known to people for several hundred years. The higher strength level would have a bad effect on the total machining bill if there was no improvement in the same technology.

In view of this significance of the problem, Merchant (1960) highlighted the necessity for development of newer concepts in metal machining. By considering an integrated plan and utilizing the results of basic and applied research, it has now become possible to process some of the materials which were formerly considered to be unmachinable under regular conditions.

Some of these methods have been exploited commercially while others are yet in their experimental stages. The developed newer machining processes are often called as “modern machining processes” or “unconventional machining processes”. The name unconventional signifies that traditional tools are not engaged for metal cutting; rather forms of energy are used in its direct form.

Modern machining processes are classified based on the type of fundamental machining energy used, like mechanical, electrochemical, chemical or thermoelectric.

PROCESS SELECTION

To make effective use of modern machining methods, it is essential to know the specific character of the machining issue. It is to be understood that:

(1) The methods can’t replace the traditional ones.

(2) A specific type of machining method found suitable under the given conditions might not be as efficient under different conditions.

A mindful assortment of the procedure for a given machining issue is the base.

Before selecting the process that must be employed, the following aspects should be studied:

(i) Physical parameters

(ii) Properties of the material and the shape.

(iii) Capability of process.

(iv) Economic evaluation

While making a comparison of the physical parameters of today’s machining processes, it might be noticed that both EDM and USM needs about the same power, whereas ECM consumes forty times more power than EDM. ECM consumes much greater power; it is an excellent method to drill long slender holes with length/diameter ratio > 20. It could be seen that for the machining of electrically non-conducting materials, both ECM and EDM are not suitable, whereas the mechanical methods can attain the desired results.

We conclude now.

Chassis And It’s Components In Automobile System

A chassis is a physical frame or structure of an automobile, an airplane, a personal computer, or any other multi-component device.

Components of the chassis

The various components and their location in a vehicle are:

Engine yields power needed to move the vehicle at the desired speed, overcoming the external resistances. This could be a SI engine or CI engine or gas engine.

Radiator is a device that is used to re-cool the hot engine cooling water for recirculation purpose. The radiator is connected by rubber hoses to the engine, to permit the cooling system water to circulate between them.

Clutch isolates the engine from the transmission system as when needed. It also allows the vehicle to be started from rest, smoothly and with jerks.

Gearbox helps the torque of the needed amount at the driving road wheels. Whenever the resistance to be overcome by the vehicle changes, the gear ratio is to be changed. The gear box serves precisely the purpose. The gearbox also helps to reverse the vehicle.

Universal joints cum propeller shaft transmit the torque from the gearbox shaft to the final drive. The gearbox is generally attached to the vehicle frame. The final drive, differential and rear axle are connected to the frame by means of springs. As the tyres of the vehicle hit bumpers on road, the rear axle moves up and down. The universal joints help the propeller shaft to attain different inclination.

Final drive transmits the torque from the longitudinal universal joints cum propeller shaft to the transverse driving half axle shafts and the wheels. The final drive also multiplies the driving torque.

Differential allows the driving wheels on the two sides of the vehicle to rotate at the same speed when moving over a straight road and at different speeds whenever the vehicle makes a turn.

Half-axle drive shafts transmit the driving torque from the final drive and differential unit to the driving road wheels.

Frame-supports the engine, vehicle body, wheels and other components.

Spring and wheels transmit the vehicle load from the frame to the road.

Special dampers slow the resultant oscillations of the springs when the wheel hits bumpers.

Electrical system consists of a battery, starting motor, generator, and controls, and in case of a spark ignition power plant the engine ignition system and lighting arrangement.

Controls in a vehicle are steering system, brake system, engine control and power train control.

Steering system changes the direction of motion of the vehicle by turning the front wheels.

Brake system ensures safe driving. With this, the vehicle can be stopped quickly, or slowed down while going down a slope. The brakes are connected to the brake pedal or lever by ways of mechanical, hydraulic or air operated devices.

Engine control is the mechanism that permits a variation in the revolutions of the engine crankshaft as the demands.

Power train control boils to engage and disengage the clutch and the gearbox. These controls, hence, make the speed and torque variation possible.

We conclude now.

If you are looking for CAD CAM certification in Pune and want to do CAD training courses, then our CRB Tech Solutions has a big name in this field for you to consider in order to enhance your skill in AutoCAD programs and grow in your field. Our CAD CAM courses are timely upgraded and our CAD CAM institute has earned a name for itself.

Computational Fluid Dynamics And Applications

Computational fluid dynamics or CFD is the science to predict fluid flow, heat transfer, chemical reactions, and related phenomena by solving mathematical equations which govern these processes using a numerical process.

CFD is sometimes referred to as flow simulation, and is a computer simulation technique that permits the fluid flow around or through any product to be analyzed in great detail.

By using this technique, designers can verify that their products will conform to a client’s needs early in the design cycle, mainly accelerating the product development process.  CFD can be used to calculate design mass-flow rates, pressure drops, heat transfer rates, and fluid dynamic forces such as lift, drag and pitching moments.

The accuracy of modern CFD methods has significantly increased the level of design insight available to engineers throughout the design process and therefore greatly reduces companies’ chances to technical risk when developing thermal and fluid-based products.  The use of CFD in design generally leads to far fewer physical prototypes being necessary during development, less prototype testing and hence lowers the time-to-market and cost-to-market substantially.

Advantages of CFD:

  • Goodinsight into systems that might be difficult to prototype or test through experimentation
  • Ability to foresee design changes and optimize accordingly
  • Predict mass flow rates, pressure drops, mixing rates, heat transfer rates & fluid dynamic forces

    Applications:

  • Aerodynamics
  • Industrial Fluid Dynamics
  • Fluid Structure Interaction
  • Heat Transfer
  • Hydrodynamics
  • Multi-phase Flows

Benefits of CFD:

  • Low cost.
  • With the help of physical experiments and tests to get essential engineering data for design could be expensive.
  • CFD simulations are relatively cheap, and costs are likely to lower as computers become more powerful.

Speed

  • CFD simulations could be executed in a short period of time.
  • Quick turnaround means engineering data could be introduced early in the design process.

Able to simulate real conditions

  • Some flow and heat transfer processes cannot be tested, e.g. hypersonic flow.
  • This provides the ability to theoretically simulate any physical condition.

Able to simulate ideal conditions

  • CFD permits great control over the physical processes, and offers the ability to isolate specific phenomena for study.

For example: a heat transfer process can be idealized with adiabatic, constant heat flux, or constant temperature boundaries.

  • Experiments permit data to be extracted at a limited number of locations in the system.
  • CFD permits the analyst to examine a large number of locations in the area of interest, and yields a comprehensive set of flow parameters for examination.

Limitations of CFD:

  • Physical models.
  • CFD relies upon physical models of real world processes.
  • The CFD solutions could only be as accurate as the physical models.

Numerical errors

  • Solving equations on a machine also introduces numerical errors.
  • Round-off error: Owing to finite word size available on the computer, round-off errors will always exist.
  • Truncation error: Owing to approximations in the numerical models.

Boundary conditions

  • Similar to physical models, the accuracy of the CFD solution is only as good as the initial/boundary conditions provided to the numerical model.

We conclude now.

Are you looking for CAD CAM certification in Pune? Well if you want to do CAD training courses, then our CRB Tech Solutions has a nice name in this field for you to take up for enhancing your skill in AutoCAD programs and grow in your career. Our CAD CAM courses are much upgraded and our CAD CAM institute has earned a niche for itself.
