Autonomous Robotic Navigation for Endovascular Brain-Computer Interface Access
A robotic system autonomously reached cerebral venous targets in bench testing, with 14 of 20 physical runs succeeding.
The paper trains Soft Actor-Critic controllers in simulation for two navigation tasks from the right internal jugular vein toward the superior sagittal sinus. Performance dropped in the unseen anatomy for one task, pointing to anatomical generalization as a limiting issue. Failure predictors caught nearly all simulated failures, but their calibration weakened after transfer to physical fluoroscopy-guided runs. ArXiv · AI/CL/LG's note
