Tamiya 71126 Mechanical Swimmer: A Versatile STEM Model Kit

The Tamiya 71126 Mechanical Swimmer is an engaging model kit designed for hobbyists and those interested in STEM concepts. This kit allows builders to explore the mechanics of movement with its unique ability to perform three distinct swimming styles: Freestyle, Butterfly, and Backstroke. By adjusting the positions of the legs, arms, and head, users can observe how different configurations affect movement.

Design and Functionality

The Mechanical Swimmer features a Submarine Motor Mini and an Underwater Gearbox, which drive the robot's limbs via crankarms. The motion is further transmitted to the arms using rubber bands, creating a realistic swimming action. This setup not only demonstrates basic mechanical principles but also provides an interactive learning experience.

Assembly and Operation

Designed with ease of assembly in mind, this snap-together model requires no additional tools, making it accessible to a wide range of ages. The kit includes a high-speed type Submarine Motor Mini equipped with two O-rings to prevent water ingress, ensuring durability during operation. Note that one AAA battery is required, which is sold separately.
