Trusted by Universities and STEM Educators Worldwide
Proven track record across leading engineering camps, robotics departments, and maker academies.
"High school students loved to program Bittle because of its organic quadruped form. They naturally understand canine movement and were fascinated by emulating those gaits in code. Using Skill Composer to create original skills made teaching kinematics far more engaging than traditional wheeled bots."
"Our Robotics & AI Lab uses these quadrupeds for both student camps and research experiments. They are agile, affordable, durable, and quick to set up. Bigger quadrupeds were cumbersome to operate and demanded enormous test areas, whereas Bittle X operates safely directly on student lab benches."
"Bittle X is hands down the most refined small-scale quadruped robotics platform on the market. From its interlocking frame architecture to its complete open-source code base, it strikes the ideal balance between turnkey classroom usability and deep developer hackability."
