Tamiya 70169 Rescue Crawler STEM Build Kit - 3 Channel  [70169]

Hands-On Mechanics with the Tamiya 70169 Rescue Crawler

The Tamiya 70169 Rescue Crawler is designed as a practical learning model that introduces basic robotics and mechanical engineering by doing. Suitable for kit-builders and students, it highlights how simple mechanisms cooperate in a mobile rescue-style vehicle.

Mobility and Track Features

Equipped with three pairs of tracks, this crawler negotiates uneven terrain with improved stability. The leading pair of track modules tilt from 80 degrees upward to 20 degrees downward to clear obstacles that a standard vehicle might not. The rear crane arm has full remote control for simulating load handling and object retrieval.

Core Components for Learning

Included are a twin motor gearbox, a 4-speed crank gearbox and a 3-channel R/C unit, providing direct exposure to motor control and gear ratios. The universal plate lets builders attach extras or experiment with layout changes for classroom demonstrations or solo projects.

Power and Batteries

Power is provided by two R20/D/UM1 batteries, which must be purchased separately. This approach keeps the kit price down while allowing choice of battery quality and brand.
