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

Quick look at the Tamiya Mechanical Dog

Get hands-on with visible mechanics using the Tamiya Mechanical Dog from the Robocraft range. This four-legged walking kit delivers a clear view of motion conversion and is well suited to hobby builders and STEM learners who enjoy mechanical projects.

Structure and motion mechanics

The model features transparent yellow body panels and legs so you can watch gears and linkages at work. Movement is produced by converting motor rotation into reciprocating motion via a crank and linkage rod system. Assembly uses screws and simple parts, so builders new to models can follow the process without complex tools.

Gait options and speed tuning

The design supports 4 different stride settings by repositioning the crank holes and two selectable gear ratios, yielding eight speed and gait combinations. This lets you adjust how smooth or lively the dog's walk appears on level floors.

Display setup and use cases

Optimised for operation on even surfaces, the Mechanical Dog can be fitted with an optional roller stay for Mini 4WD course use or kept as a desktop display. The transparent switch and yellow parts give a technical, modern look while keeping function visible.
