Pololu Tamiya 71109 Mechanical Tiger - Four Legged Walking Type

The Tamiya 71109 Mechanical Tiger - Four Legged Walking Type is a fascinating blend of engineering and play. With a total length of 15.5 cm and a weight of 105 g (excluding batteries), this transparent yellow ABS resin model showcases the intricate workings of its motor, gears, cranks, and linkage rods. The kit includes a gearbox, motor, control switch, and decorative stickers, providing everything needed to bring this mechanical creature to life.

Perfect for budding engineers and hobbyists, this mechanical tiger offers a hands-on learning experience. The motor's rotation is cleverly transferred to the legs through crank plates and linkage rods, allowing the tiger to walk. You can customize its movement with four different strides and two gear ratios, resulting in eight possible speed settings. A reverse switch adds the ability to move backward, enhancing the tiger's versatility.

The Mechanical Tiger is not just a toy; it's a tool for understanding mechanics. By assembling the kit, users gain insights into how gears and motors work together to create movement. This educational aspect makes it an excellent choice for classroom projects or at-home STEM learning.

Designed for ease of assembly, the kit requires only a screwdriver, which is included, and no soldering is necessary. It runs best on flat, smooth surfaces, making it ideal for indoor exploration. The model is powered by a single AA battery (sold separately), providing up to two hours of continuous operation, ensuring plenty of time for experimentation and fun.

Note: This is a kit that requires assembly by snapping parts together and using a screwdriver. It is recommended to avoid using it on slopes, bumpy roads, or thick carpets for optimal performance.
