Reinforcement Learning Enables Autonomous Microrobot Navigation and Intervention in Simulated Blood Capillaries
arXiv:2606.26154v1 Announce Type: cross Abstract: Autonomous microrobots navigating biological vasculature could enable targeted drug delivery and thrombolysis, yet training control policies for realistic environments remains an open challenge. Prior reinforcement learning (RL) studies of microrobotic navigation have been limited to idealized geometries that omit complex hydrodynamic flow fields, confined branching structures, and dense cellular obstacles found in vivo. Here, we develop a physically grounded simulation of a blood capillary network, incorporating realistic hydrodynamic flow fie
Advances in reinforcement learning and micro-robotics are converging, making complex autonomous navigation within biological systems increasingly feasible. Realistic simulation environments are crucial for robust policy training, addressing previous limitations in simplified models.
This development indicates meaningful progress toward using autonomous microrobots for precise in-vivo medical interventions, potentially revolutionizing targeted drug delivery and minimally invasive therapies.
The ability to train microrobots in physically grounded simulations of complex biological environments moves them closer to practical application within the human body, overcoming significant hurdles in autonomous control.
