Lesson notes

Key points

Manipulator: Links joined by joints form the robot's arm.
Actuators: Motors, hydraulics or pneumatics drive each joint.
Sensors: Encoders and cameras measure the robot and its world.
Controller: The controller compares target with measurement and corrects.
Kinematics: Kinematics links joint angles to end effector position.
End effector: The gripper or tool does the actual job.

Takeaway: Arm, actuators, sensors, controller, kinematics, tool: that's a robot.

Quick check: Which robot subsystem converts energy into joint motion?

Sensors
Actuators
End effector

Actuators such as electric motors physically drive the joints.
