Tamiya 71101 Mechanical Dog Four-Leg Robocraft Build Kit  [71101]

Meet the Mechanical Dog from Tamiya

Explore basic robotics with the Tamiya Mechanical Dog, a Robocraft model that highlights mechanical linkages. The four-legged walker is aimed at model makers and educators who want a hands-on demonstration of motion mechanics.

Visible engineering and simple assembly

Clear yellow bodywork and leg panels reveal the internal gearbox and linkage rods. The walking action is created by converting motor rotation into a reciprocating motion through a crank and linkage setup. Parts attach with screws and the build sequence is straightforward for those new to construction kits.

Adjustable gait and speed choices

You can select from 4 stride settings by moving the crank pin and choose between two gear ratios, producing eight different speed and gait configurations. These settings let you experiment with how stride length and cadence affect movement.

Use, display and course adaptation

Best used on flat, even surfaces, the Mechanical Dog can be adapted for Mini 4WD tracks with an optional roller stay or presented as a mechanical display piece. The clear on-off switch and transparent yellow components keep the mechanism visible while running.
