Object Tracking from Unstabilized Platforms by Particle Filtering with Embedded Camera Ego Motion [PDF]

open access: yes, 2009
Visual tracking with moving cameras is a challenging task. The global motion induced by the moving camera moves the target object outside the expected search area, according to the object dynamics.

A Quadratic Nonlinear Prediction-Based Heart Motion Model following Control Algorithm in Robotic-Assisted Beating Heart Surgery

open access: yesInternational Journal of Advanced Robotic Systems, 2013
Off-pump coronary artery bypass graft surgery outperforms the traditional on-pump surgery because the assisted robotic tools can cancel the relative motion between the beating heart and the robotic tools, which reduces post-surgery complications for ...

Function based control for bilateral systems in tele-micromanipulation [PDF]

open access: yes, 2008
Design of a motion control system should take into account (a) unconstrained motion performed without interaction with environment or any other system, and (b) constrained motion with system in contact with environment or other systems.
