Tamiya 71101 Mechanical Dog Four-Legged Walk Robot Kit  [71101]

Overview of the Mechanical Dog kit

The Tamiya Mechanical Dog brings mechanical linkages to life in an easy to assemble Robocraft model. Its four-legged motion provides a clear example of how rotary power can be translated into walking movement for hobbyists and collectors.

Construction and visible parts

Transparent yellow components expose the gearbox, crank and linkage rods so builders can inspect internal movement. The walking action is produced by a crank and linkage conversion of motor rotation, and assembly mainly uses screws for secure fitting.

Fine tuning gait and velocity

Select between 4 stride patterns via crank hole placement and two gear ratios to create eight total speed/gait combinations. This lets you refine how the walker behaves on a flat display surface.

Practical use and styling notes

Designed to run smoothly on level floors, the Mechanical Dog can be adapted for Mini 4WD circuits with an optional roller stay or kept as a shelf model. The clear power switch and yellow transparent parts give it a technical, modern look.
