Beetlebot 3 in 1 Robot for Pico
Download Resources:
Decription：
The Beetlebot smart robot, compatible with LEGO building blocks, is a STEM educational product which can automatically dodge obstacles, follow black lines and light to move. Besides, it has three cool forms such as the soccer robot, the siege robot, the handling robot. As for beginners, they cancreate whatever they want by LEGO building blocks.
Various improvements have been made on the Beetlebot car in comparison with other smart cars. It integrates a motor driver and a large number ofsensors and is easy to assemble. Beetlebot’s control core is today’s mainstream open source hardware, which allows it to implement low-cost programming learning programs.
Going forward, not only can it impart basic programming knowledge and AI application to children and the youth, but also it can cultivate their creativity, hands-on ability, problem-solving capability, interpersonal communication as well as teamwork ability. With this kit, you have a chance to experience soccer games using your own robots.
