Tamiya 71123 Sumo Wrestler Robot Kit - Robocraft Series No.23 Collector Edition  [71123]

Tamiya 71123 Wind-Up Sumo Wrestler Robot

The Tamiya Sumo Wrestler Robot kit pairs approachable assembly with clear STEM lessons, making it a solid pick for hobbyists and young builders exploring mechanical basics. As part of the Robocraft Series, the 71123 model uses a wind-up generator to power the robot so no batteries are needed.

Practical Hands-On Mechanics

This kit gives a tangible way to learn about gears and basic electricity. Turn the generator handle clockwise to drive the robot forward, and reverse the handle to make it back up. The direct link between winding the generator and the robot's motion helps builders see how mechanical input creates movement.

Shows Well on a Shelf

Beyond the learning aspect, this Sumo Wrestler makes an appealing display piece with visible generator parts that spark conversation. The included 50cm cable connects the generator to the robot, adding realism to the finished model.
