Attention-Based Markerless Pose Estimation of the Assistant-Port Trocar in Robot-Assisted Surgery with a Head-Mounted Display

ICRA 2026poster

In robotic-assisted minimally invasive surgery, an assistant surgeon stands at the bedside to insert and manipulate instruments while the primary surgeon operates the robot. Augmented reality (AR) head-mounted displays (HMDs) may improve the assistant's spatial awareness, but require tracking of sur…

"Good Robot!": Efficient Reinforcement Learning for Multi-Step Visual Tasks with Sim to Real Transfer

RA-L 2020

Current Reinforcement Learning (RL) algorithms struggle with long-horizon tasks where time can be wasted exploring dead ends and task progress may be easily reversed. We develop the SPOT framework, which explores within action safety zones, learns about unsafe regions without exploring them, and pri
