Tamiya 71122 4-Legged Wind-Up Robocraft Model  [71122]

Robocraft Series Tamiya 71122 Wind-Up Walker

The Tamiya 71122 from the Robocraft Series is a battery-free, wind-up four-legged robot built from clear plastic so the internal mechanics are visible. It is tailored for people curious about mechanical systems and simple engineering principles.

Visible Mechanisms and Movement

Clear components let you observe gear trains and linkages in motion. Operating the crank clockwise propels the unit forward and reversing the crank makes it walk back. Small moving features like the eye swing and tail vibration add fun motion.

Educational Benefits and Display Use

Perfect for classroom demonstrations or a hobby shelf, the kit helps illustrate energy conversion and basic machine elements. Once assembled, it doubles as a conversation piece showing mechanical ingenuity without electronics.
