MiniRHex Makes Wiggly-Legged Unstoppability Tiny and Affordable
RHex (pronounced “rex”) is a unique hexapedal robot that uses hybrid wheel-legs (whegs) to get around. It’s surprisingly adaptable, able to adjust its gait to conquer a variety of obstacles and terrains, and it can even do some impressive parkour. RHex has been around for nearly two decades, which is practically forever in robot years, but because of how versatile it is you still see it doing cool new stuff from time to time.
Carnegie Mellon University’s Robomechanics Lab uses a fancy US $20,000 version of RHex called X-RHex Lite “to explore the connection between dynamic locomotion and perception,” but they’ve only got one robot since it’s wicked expensive, which limits the amount of research and outreach they can do. To fix this, they’ve designed a much smaller version of RHex called MiniRHex that you can build yourself for about $200. And it’s adorable.
