Inverse Dynamics vs. Forward Dynamics in Direct Transcription Formulations for Trajectory Optimization
Henrique Ferrolho, Vladimir Ivan, Wolfgang Merkt +2
Benchmarks of state-of-the-art rigid-body dynamics libraries report better performance solving the inverse dynamics problem than the forward alternative. Those benchmarks encourage…
Memory Clustering using Persistent Homology for Multimodality- and Discontinuity-Sensitive Learning of Optimal Control Warm-starts
Wolfgang Merkt, Vladimir Ivan, Traiko Dinev +2
Shooting methods are an efficient approach to solving nonlinear optimal control problems. As they use local optimization, they exhibit favorable convergence when initialized with a…
Modeling and Control of a Hybrid Wheeled Jumping Robot
Traiko Dinev, Songyan Xin, Wolfgang Merkt +2
In this paper, we study a wheeled robot with a prismatic extension joint. This allows the robot to build up momentum to perform jumps over obstacles and to swing up to the upright…
Optimizing Dynamic Trajectories for Robustness to Disturbances Using Polytopic Projections
Henrique Ferrolho, Wolfgang Merkt, Vladimir Ivan +2
This paper focuses on robustness to disturbance forces and uncertain payloads. We present a novel formulation to optimize the robustness of dynamic trajectories. A straightforward…
