• Summarize the kinds of
robots ?
• Explain the parts of a
robot and how does it
move ?
• Mention the applications
of robots ?
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
• Appendages
Shoulder
Arm
Grippers
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
