Tamiya 71102 Mechanical Kangaroo Two-Leg Jumper Kit  [71102]

Compact jumping model for makers

The Tamiya 71102 Mechanical Kangaroo merges simple robotics with mechanical learning, giving makers a practical project that demonstrates how linkage and gearing create lifelike movement. The mechanism reproduces the kangaroo's hop and step behaviors.

Exposed mechanics and motion modes

Clear body parts let you observe the gearbox and linkages as they move the rear legs. The kit includes two gear settings so you can switch between a slower, balanced walk and a quicker tail-supported run.

Build tips and steering by tail angle

Assembly is straightforward, using pre-marked spots, screws and snap-fits. Changing the tail angle adjusts steering and balance, offering a hands-on lesson in center of mass and directional control.

Where to run the model

Ideal on level indoor surfaces; uneven ground will interfere with the mechanism. Its amusing gait is useful for demonstrations of mechanical concepts and basic robotics.
