A three-legged robot named SpaceHopper has been developed to combat the challenges of exploring low-gravity environments. The robot, with its triangular body and articulated legs, can perform hopping movements to navigate surfaces on asteroids or moons. The SpaceHopper program was initiated as a student research project at ETH Zurich university and has recently been tested in a simulated environment.

A knee and a hip joint on each leg allow the robot to perform hopping movements to combat low gravity environments.A three-legged robot named SpaceHopper could help combat the challenges of exploring low-gravity environments , such as those found on asteroids or moons.
The SpaceHopper program was first launched two and a half years ago as a student research project at ETH Zurich university in Switzerland. And recently, researchers tested the hopping robot in a simulated The robot consists of a triangular body with an articulated leg at each corner. Each of these three legs has a knee and a hip joint, allowing the robot to push off from a surface, kick to propel itself throughand control its landing within a designated area. SpaceHopper is designed specifically to explore relatively small celestial bodies such as" are thought to contain valuable mineral resources that could be of use to humankind in the future," researchers said in the statement."The exploration of these bodies could also give us insights into our universe's formation." However, exploring these types of celestial bodies can be challenging. In an environment with almost no gravity, there is basically no traction between a spacecraft's wheels and the surface it drives across; there is barely any atmosphere for a spacecraft to fly through, if there is one at all. That's why SpaceHopper instead performs brief hops to move upwards and sideways. allowed the researchers to simulate the low-gravity conditions in which SpaceHopper may one day be deployed. A video taken during the flight shows SpaceHopper kicking each of its three legs in coordinated movements to stay lifted during periods of zero gravity, which occurred about 30 times per flight, for about 20-25 seconds each.
