What kinds of robots are

there?

Types of robots

• are automatic machines that extend human potential.

• do work that humans can but should not do.

Simple Level Robots:

Types of robots

• are programmable, multipurpose, electromechanical machines.

• do work that humans normally do.

Middle Level Robots:

Types of robots

• are reprogrammable, multifunctional, manipulators.

• are designed to move materials, tools and parts through programmed paths.

• are suited for a variety of tasks.

Complex Level Robots:

What are the parts of a robot?

•Manipulator

•Pedestal

•Controller

•End Effectors

•Power Source

Manipulator(Mimics the human arm)

• Base

• AppendagesShoulderArmGrippers

Pedestal

(Human waist)

• Supports the manipulator.

• Acts as a counterbalance.

Controller(The brain)

• Issues instructions to the robot.

• Controls peripheral devices.

• Interfaces with robot.

• Interfaces with humans.

End Effectors(The hand)

• Spray paint attachments

• Welding attachments

• Vacuum heads

• Hands

• Grippers

Power Source

(The food)

• Electric

• Pneumatic

• Hydraulic
