What kinds of robots are there?
7
Types of robots
Simple Level Robots

• are automatic machines that extend human
  potential.
• do work that humans can but should not do.

8
Types of robots
Middle Level Robots

• are programmable, multipurpose, electromechanical
  machines.
• do work that humans normally do.

9
Types of robots
Complex Level Robots

• are reprogrammable, multifunctional,
  manipulators.
• are designed to move materials, tools and parts
  through programmed paths.
• are suited for a variety of tasks.

10
What are the parts of a robot?

• Manipulator
• Pedestal
• Controller
• End Effectors
• Power Source

11
Manipulator
(Mimics the human arm)

• Base

• Appendages

• Shoulder

• Arm

• Grippers

12
Pedestal
(Human waist)

• Supports the manipulator.
• Acts as a counterbalance.

13
Controller
(The brain)

• Issues instructions to the robot.
• Controls peripheral devices.
• Interfaces with robot.
• Interfaces with humans.

14
End Effectors
(The hand)

• Spray paint attachments
• Welding attachments
• Vacuum heads
• Hands
• Grippers

15
Power Source
(The food)

• Electric
• Pneumatic
• Hydraulic
