Tamiya 70211 Arm Crawler Educational STEM Build Kit  [70211]

Explore Mechanisms with the Tamiya 70211 Arm Crawler

For young makers keen to learn by doing, the Tamiya 70211 Arm Crawler Assembly Kit provides an interactive platform to study mechanical concepts. As part of the STEM series, it focuses on practical assembly and observation of moving parts.

How the Tracks and Arms Work

The model features four rotating tracks located two on the body and one on each arm, giving it good adherence on many surfaces. The arms rotate independently so the machine can climb over obstacles up to 45mm, showing how torque and grip affect movement.

Assembly Notes

The package contains all components for construction, combining snap-fit elements with screws to keep the build accessible. Basic wiring is included and the motor has a factory-fitted switch for easier setup. A rear stay helps stop the crawler tipping when negotiating inclines.

Compatibility and Optional Parts

Performance can be extended using accessories such as the Twin-Motor Gearbox (item 70097) and the 2-Channel Remote Control Box (item 70102). These upgrades are useful for testing remote operation and multi-motor arrangements.
