UT-SEA: Compact, High Power, Light-Weight, Series Elastic Actuator
UT-SEA is a compact, light-weight, high-power actuator designed to enable energetic and high speed locomotion in electrically actuated legged systems. It uses a ballscrew as the primary speed reduction mechanism resulting in very high operating efficiency. The actuator is mounted on a set of springs which allows it to tolerate impact loads, store energy, and control force with high fidelity.
