  1. Robotics is the design, construction, and operation of robots. Technology Interactions

  2. How Robotics Developed • Machines designed to imitate human actions existed over 3,000 years ago. • First-generation robots were designed for factory work. • Second-generation robots can perform more complex tasks.

  3. Robotic Systems Have Five Parts • Controller—a computer that serves as the robot’s brain; contains the computer program • Computer program—coded instructions for the robot to follow • Manipulator—the robot’s mechanical system • End effector—the robot’s hand • Power supply—electric, hydraulic, or pneumatic

  4. Degrees of Freedom • Degree of freedom is a robot’s ability to move in a particular direction. Each degree of freedom requires a separate joint. • Most robots have at least 6 degrees of freedom.

  5. Power for Robotic Movements • A robot’s power source is an actuator. • Pneumatic and hydraulic systems are used when heavy lifting is needed.

  6. Controlling Robotic Systems • Computer programming • Flowcharts are prepared to describe the basic movements of the robot. • Instructions for these movements are turned into binary code the robot can read.

  7. Feedback Control • Feedback control is the process of sending signals, interpreting them, and adjusting through signals. • Robots get information about their environment through sensors, cameras, scanners, and microphones.

  8. Modern Robots • Industrial robots perform tasks such as welding, spray painting, and assembly. • Medical robots assist in surgery, transport hospital supplies, and dispense medicine. • Assistive robots help people with disabilities perform everyday tasks. • Household robots do tasks such as vacuuming floors or cutting grass.
