Mixed-Integer vs. Continuous Model Predictive Control for Binary Thrusters: A Comparative Study
Franek Stark, Jakob Middelberg, Shubham Vyas
Binary on/off thrusters are commonly used for spacecraft attitude and position control during proximity operations. However, their discrete nature poses challenges for conventional…
Quadrupeds for Planetary Exploration: Field Testing Control Algorithms on an Active Volcano
Shubham Vyas, Franek Stark, Rohit Kumar +6
Missions such as the Ingenuity helicopter have shown the advantages of using novel locomotion modes to increase the scientific return of planetary exploration missions. Legged robo…
An adaptive hierarchical control framework for quadrupedal robots in planetary exploration
Franek Stark, Rohit Kumar, Shubham Vyas +6
Planetary exploration missions require robots capable of navigating extreme and unknown environments. While wheeled rovers have dominated past missions, their mobility is limited t…
Benchmarking Different QP Formulations and Solvers for Dynamic Quadrupedal Walking
Franek Stark, Jakob Middelberg, Dennis Mronga +2
Quadratic Programs (QPs) are widely used in the control of walking robots, especially in Model Predictive Control (MPC) and Whole-Body Control (WBC). In both cases, the controller…
