Why we recommend it

A no-solder, no-code starter arm aimed at kids and classrooms. Everything assembles with a screwdriver, and the motion is mechanical/electronic rather than programmed, so a younger builder can finish it in a sitting and immediately understand joints, links and grippers. It is not the arm you will program with Arduino, but it is an excellent, inexpensive way to introduce the mechanics of a robotic arm before stepping up to a servo-driven, code-controlled build like the LeArm.
