Palm-sized robot makes controlled jumps using a tiny electric motor

AI-summarised brief · reviewed before publication

Engineers at the University of Washington unveiled DirectHop, a palm‑sized robot that hops without springs, clearing a standard stair step and righting itself after landing. The prototype uses a tiny electric motor and three folding legs, allowing jump height to be set with single‑centimeter precision by adjusting motor current. A roll cage inspired by a box turtle keeps the robot upright, enabling a 90% self‑righting rate. DirectHop is powered by wired electricity and lacks autonomous navigation, but future versions aim for solar power, onboard batteries, and autonomous stair‑climbing.

💡 Why It Matters

  • · DirectHop demonstrates that miniature robots can use controlled hopping to navigate obstacles, offering a low‑cost alternative for inspection and exploration tasks where traditional wheeled or flying robots struggle.
