High-rise buildings could soon revolutionize their energy management by adopting gravity energy storage systems. Recent ...

Abstract: We describe a new physics engine tailored to model-based control. Multi-joint dynamics are represented in generalized coordinates and computed via recursive algorithms. Contact responses are ...
