To Define a machine as a robot the follow properties must be met

1. Automated - automated machine can operate without need of a human to assist it.

2. Reprogrammable - reprogrammable machine can be reprogrammed to perform its task in different way.


3. Multitasking - multitasking machine  can be programmed to do entirely different task such as assembly or machine loading, or milling.

The ability to do different kinds of application makes a robot different from other machines.

 

Common robotic applications

1. Assembly

2. Material handling

Conveyor Transfer - Robots are often used to transfer parts to or from a conveyor.

Palletizing- is a process where parts re placed in a carton for transport.

Safety Note- It is important to consider the path the robot will take from point to point so that it does not hit an object or move in an inefficient manner. .

3 Welding

4. Machine loading  - robots are used to load  and unload all kinds of machines including CNC mills, punches, CNC lathes, drill presses, die casting, injection molding, presses, and even libratory test tube machines

5. Painting

6. Gluing

Advantages of Robots

1. Improve Quality of life- Robots can work in dangerous or dirty environments here people should not be working.  They are also great for repetitive and boring tasks.

2. Improve product quality - Robots can perform their tasks very accurately on a consistent basis causing fewer reject.  Robots can do certain task better such a spray painting.

3. Reduce Production Costs - Robots can operate continuously 24 hours a day.  They do not have to be paid salary's or benefits.

Five Basic Robot Components

1. Manipulator (arm) - manipulator is the part of the robot that actually moves and reaches.  

2. End Effectors (hand) - The end effector is used to grasp parts or tools.  One type is gripper the other End of Arm (EOA) tooling.

End of Arm Tooling (EOA) allows the robot a more active role by enabling the robot to perform work on an object such as drilling, welding, gluing, cuttin or performing some other task to an oject.

Gripper are the most common type of robotic end effector. -

1. 2 Point curvilinear gripper- has two fingers that close on the part.  Often pneumatic powered.

2. 2 point parallel gripper - had two fingers the finger do not rotate about a point.

3. Controller - the controller is a specialized computer (programmable logic controller PLC) that coordinates the robot's movements.

4. Drives - the robot's drives, located inside the controller, consist of electronic circuit cards that supply power tot he robot arem's motors

5. Teach Pendant - the teach pendant is a hand-held device that allows the robot operator to program and controls robot.
