What kinds of robots are there?

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

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

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.

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
