Tamiya 71117 Sliding Ladybug Retro Vibrating STEM Kit  [71117]

Tamiya 71117 Sliding Ladybug - Playful STEM Build

The Tamiya 71117 Sliding Ladybug blends a fun animal design with introductory engineering concepts so kids can build and observe motion first-hand. The project makes mechanical principles visible and engaging.

Vibration Drive Explained

A Type 130 motor turns a weighted plate to produce vibrations that move the model across the floor. Movement relies on three contact rods that translate vibration into forward sliding, and small adjustments alter how it steers.

Build Steps and User Experience

Snap-fit pieces and a few screws keep assembly approachable while teaching step-by-step construction. The ladybug eyes double as rollers to smooth passage over minor hurdles on level surfaces.

Play Ideas and Power Needs

Set up short races or obstacle runs using household items to explore performance differences. The model works best on smooth floors and needs one R1/AAA/UM4 battery, which is not included.
