 Robots with legs have significant advantages over wheeled robots. Nature has many elegant forms of locomotion, which can inspire robotics. Enter Omni-leg, a robotic leg based on a simplified human leg structure. Omni-leg's upper leg is driven by two motors, enabling symmetrical transitional movement in three dimensions. And the lower leg is driven by a single motor, enabling linear movement. This structure makes the robot leg have a completely symmetrical workspace in space and has the potential to achieve omnidirectional motion. In contrast, most leg mechanisms, and thus the robots they're attached to, have one single direction of motion. This prevents those robots from being able to turn in tight spaces. So far, the researchers have modeled Omni-leg and tested a single leg version. More testing with multiple Omni-legs on a robot are needed, but this work could lead to more adaptable, maneuverable robots.
