CADeT: Causal-Aware Deformation Transmission for Indirect Robotic Manipulation of Soft Tissue

Indirect manipulation of deep-seated deformable anatomy inaccessible to the robot is challenging in robot-assisted minimally invasive surgery (RAMIS) because intervening tissues spatially filter deformation transmission. Passive observations can be ambiguous because the Decoupled and Blocked modes may produce similar m...

PICO: Projection-Informed Consistency Optimisation for 6DoF surgical tool pose estimation.

PURPOSE Accurate 6 DoF pose estimation of surgical tools is critical for automation, robotic proprioception, and safe interaction with the tissue operated on. Kinematics-based approaches suffer from accumulated errors due to the cable-driven nature of robotic arms, while vision-based methods often rely on external mark...
