Kids OK, with an adult
DIY project. Children must build this only with an adult (16+ years) beside them at all times. Not suitable for children under 8 years.
Do not power the servos from the Nano 5V pin.
Strictly follow the description given with this video.

How it works
- The shoulder and elbow servos move together, joint by joint, so the arm never dips into a V.
- The gripper servo opens and closes on the block.
- The arm lifts, swings over, lowers and releases.
- The servos run from their own 5V 3A supply with a common ground.
