Chapter 1: Parts of a Robotic Arm

Idea: A robot arm is a human arm made of metal.

Mapping: Bones = Links, Joints = Joints, Hand = End-effector, Muscles = Motors.

Selected Part: None

Hover over the robot/human arm parts to learn. Click to lock.

Try this:

Move J2 slowly. Watch: human shoulder lifts smoothly, robot follows your speed. Then bend J3 near max to feel “limit” warning glow.

What you are learning

You are learning the “anatomy” of robot arms: base, joints, links, and end-effector — with human comparison.
