Temporal logics and formal synthesis for robot planning and control
Jana Tumova, Joris Verhagen, Matti Vahs
As robots move from controlled environments into real-world settings, it becomes increasingly crucial to ensure that they perform as expected. A key step toward that goal is a rigo…
Safety-critical Control Under Partial Observability: Reach-Avoid POMDP meets Belief Space Control
Matti Vahs, Joris Verhagen, Jana Tumova
Partially Observable Markov Decision Processes (POMDPs) provide a principled framework for robot decision-making under uncertainty. Solving reach-avoid POMDPs, however, requires co…
Validation of Space Robotics in Underwater Environments via Disturbance Robustness Equivalency
Joris Verhagen, Elias Krantz, Chelsea Sidrane +9
We present an experimental validation framework for space robotics that leverages underwater environments to approximate microgravity dynamics. While neutral buoyancy conditions ma…
Exact Smooth Reformulations for Trajectory Optimization Under Signal Temporal Logic Specifications
Shaohang Han, Joris Verhagen, Jana Tumova
We study motion planning under Signal Temporal Logic (STL), a useful formalism for specifying spatial-temporal requirements. We pose STL synthesis as a trajectory optimization prob…
Collaborative Object Transportation in Space via Impact Interactions
Joris Verhagen, Jana Tumova
We present a planning and control approach for collaborative transportation of objects in space by a team of robots. Object and robots in microgravity environments are not subject…
Towards Open-Source and Modular Space Systems with ATMOS
Pedro Roque, Sujet Phodapol, Elias Krantz +11
In the near future, autonomous space systems will compose many of the deployed spacecraft. Their tasks will involve autonomous rendezvous and proximity operations with large struct…
