Lesson notes

Key points

Manipulator: The arm: links connected by joints that move the end-effector.
End-effector: The tool at the arm's tip, like a gripper, welder or drill.
Actuator: Converts energy into motion: electric motors, hydraulic or pneumatic cylinders.
Sensor: Measures the robot or world, like encoders for joint angles.
Controller: Compares sensor feedback with the target and commands the actuators.
Workspace: Every point the end-effector can physically reach.

Takeaway: Sense, decide, act: sensors, controller, actuators.

Quick check: What component turns energy into motion at a robot's joints?

Encoder
Actuator
End-effector

Actuators such as motors or cylinders produce the motion; encoders only measure it.
