2. • Summarize the kinds of
robots ?
• Explain the parts of a
robot and how does it
move ?
• Mention the applications
of robots ?

3. Types of robots
• are automatic machines that
extend human potential.
• do work that humans can
but should not do.
Simple Level Robots:

4. Types of robots
• are programmable, multipurpose,
electromechanical machines.
• do work that humans normally do.
Middle Level Robots:

5. 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:

6. What are the parts
of a robot?
•Manipulator
•Pedestal
•Controller
•End Effectors
•Power Source

7. Manipulator
(Mimics the human arm)
• Base
• Appendages
Shoulder
Arm
Grippers

8. Pedestal
(Human waist)
•Supports the
manipulator.
•Acts as a
counterbalance.

9. Controller
(The brain)
• Issues instructions to
the robot.
• Controls peripheral
devices.
• Interfaces with robot.
• Interfaces with
humans.

10. End Effectors
(The hand)
• Spray paint
attachments
• Welding attachments
• Vacuum heads
• Hands
• Grippers

11. Power Source
(The food)
• Electric
• Pneumatic
• Hydraulic
