Sea otter robot

Learn about mechanical motion while building an adorable aquatic companion with the Tamiya Swimming Sea Otter. Part of the Educational Construction Series, this engaging model uses a submarine motor to propel its tail from side to side while a clever cam mechanism simultaneously moves its forepaws in a realistic shell-cracking motion, just like a real sea otter.

Designed for builders of all skill levels, the kit features a straightforward assembly process using push rivets and a minimal number of screws. Water-resistant stickers add the finishing touches, while the completed model demonstrates how rotational motion can be converted into realistic reciprocating movement as it swims across the water.
