Tamiya 70256 Bipedal Walking Robot - Introductory Mechanics Kit

The Tamiya 70256 Bipedal Walking Robot provides a clear, hands-on introduction to mechanical walking using a compact assembly. It helps users observe how shifting balance and gearing create steady forward motion.

Construction and Motion

Produced in ABS plastic, the walking action relies on a weight transfer unit that shifts the centre of gravity. A low RPM type 130 motor turns the mechanism so the legs move forward while the chassis rocks side to side.

Putting It Together

The kit mixes snap-fit components with screws to make assembly straightforward. Pre-drilled holes in the legs and slides let you attach extra hardware like universal shafts or custom parts. Expect to spend roughly 120 to 180 minutes building the model, which rates 3 out of 5 for difficulty.

Tuning and Operation

At a gear ratio of 114.7:1 the robot travels about 4.8 cm/s, which is best on flat surfaces. Adjust the gearbox angle to steer, tweak the leg limiters for different lean and stride, and clip on the optional guide rod to help navigate obstacles.
