Tamiya 71101 Mechanical Dog Robocraft Four-Leg Walking Model  [71101]

Tamiya Mechanical Dog kit summary

Investigate mechanical motion with the Tamiya Mechanical Dog from the Robocraft series. This four-legged walker is aimed at model builders who enjoy seeing how linkages and gears convert rotary motion into walking movement.

Visible mechanism and build notes

The kit uses transparent yellow body parts so you can watch the gearbox, crank and linkage rods in action. Walking is achieved by converting motor rotation into reciprocating motion via a crank and linkage arrangement. Assembly is screw-based and accessible for most hobbyists.

Stride settings and gear selection

There are 4 stride types selectable by changing crank hole positions and two gear ratios to choose from, giving eight combined speed and gait outcomes. These choices let you dial in a preferred walking style on flat surfaces.

Running conditions and optional modifications

Best run on even floors, the Mechanical Dog can be modified with an optional roller stay for Mini 4WD use or kept as a demonstration model. The clear switch and yellow transparent pieces provide a neat, technical finish.
