Tamiya 70271 Walking & Swimming Penguin Robocraft STEM Kit  [70271]

Tamiya 70271 Walking & Swimming Penguin Robocraft STEM learning kit

Tamiya 70271 Walking & Swimming Penguin is an educational Robocraft assembly kit that showcases a battery-powered mechanism capable of switching between walking and swimming motions as part of Tamiya's Robocraft STEM line.

The model is intended for build-and-learn activities rather than speed or Mini 4WD competition. Its drivetrain uses a straightforward mechanical layout to alternate leg-like motion with a basic swimming action, driven by a single AAA battery. Molded parts are supplied for assembly, making this suitable for classroom use, hobbyist exploration of mechanical linkages, or as a display piece among STEM models.

Assembly introduces common modelling tasks such as removing parts from runners, meshing gears and shafts, and routing the motor drive into the two-mode mechanism. This kit is not based on a Mini 4WD racing chassis, so it should not be modified for competitive upgrades. Standard hobby tools are usually enough for assembly and the instruction leaflet explains how to switch between walking and swimming modes.

• Power source: single AAA battery runs the small motor and drivetrain.
• Function: alternates walking and swimming actions via a simple mechanical drivetrain.
• Finish: parts are molded; painting and decals are optional for display finish.
• Compatibility: made as an educational Robocraft kit, not for Mini 4WD race conversions.

As a non-racing Robocraft kit, this assembly offers a clear introduction to simple linkages and two-mode motion, ideal for builders seeking an instructional, display-oriented project.
