A budget DIY arm that leans into the build experience: assembling the linkages and the mechanical hand teaches how a gripper converts a single motion into a pinch. Positioned as a STEM gift for ages 8–16, it sits between a pure toy and a programmable arm — a solid weekend project that makes the leap to servo-driven arms feel natural afterwards.
