A method for planning legged robot locomotion leverages the Affine Geometric Heat Flow framework, encoding hybrid dynamics and constraints into a time-varying Riemannian metric. This approach generated dynamic hopping motions on uneven terrain, automatically determining contact points and forces while satisfying all physical constraints.
Key insights
- Hybrid dynamics and constraints of legged robots can be naturally integrated into a continuous geometric framework through a time-varying Riemannian metric.
- The AGHF method automatically determines contact points and forces, reducing the need for manual pre-planning common in other motion planning approaches.
- The computational complexity of the AGHF's parabolic PDE solution scales polynomially with the robot's state dimension, suggesting scalability for complex systems.
