HopTo's Hop-1 Robot Uses Hopping to Cut Energy Use by 75%
MarwaEldiwiny · x · 2026-08-17
HopTo's Hop-1 is a hybrid hopping-and-flying robot designed for rough terrain, utilizing passive dynamics to improve energy efficiency.
Design Logic:
- Continuous flight burns significant energy fighting gravity; the robot spends most time bouncing on a passive spring instead.
- Rotors mainly steer, replenish lost energy, and fully engage only when flight is necessary.
- Efficiency: Hopping uses around 25% of the energy of continuous flight.
- Mimics passive adaptation seen in bird feet when encountering obstacles.
