Tamiya 71104 Mechanical Ostrich STEM Robocraft Walker Kit  [71104]

Tamiya 71104 Mechanical Ostrich Kit Summary

The Tamiya 71104 Mechanical Ostrich kit is an accessible project that teaches basic mechanical principles through a two-legged walking model. Part of the STEM Robocraft line, the kit uses transparent components so builders can watch how crank plates and linkages transfer motor motion into leg movement.

Mechanics and Motion

This ostrich-style walker copies the long-legged gait of the real bird, using a compact arrangement of motor and battery to keep weight balanced for steady walking. The clear switch with blue transparent parts gives a neat visual cue while keeping the mechanism visible.

Assembly Notes and Recommended Surfaces

Assembly is straightforward, combining screws and snap-fit parts to suit newcomers and seasoned hobbyists alike. The model performs best on flat, even surfaces and is not designed for steep slopes or rough ground. It takes one R6/AA/UM3 battery and will run for roughly 1.5 hours on a fresh alkaline cell.
