Tamiya 70218 Manta Ray Swimming Robot Kit - Classroom Edition  [70218]

Tamiya 70218 Manta Ray Swim Project

The Tamiya 70218 Manta Ray Swim Assembly Kit encourages practical learning by letting builders construct a small swimming model. Its flexible fin is engineered to imitate a manta ray's glide, powered by a compact submarine motor for realistic motion in a calm water test.

Assembly and Motion

The model is 160mm long, 148mm wide and 55mm tall, sized to visibly show the fin action. The build uses simple snap and screw fittings so newcomers can get the kit together quickly. The fin is driven through a shaft from the submarine motor while the tail fin gives directional control.

Educational Benefits

This kit introduces mechanical topics like linkages and propulsion along with basic electrical concepts when you install the motor and battery. It needs one AAA battery to run, making it an easy illustration of how power sources drive small mechanisms.
