Minimally-Back-Drivable Robots for Rehabilitation: Path-Adherent Permissiveness Control via Trajectory Adaptation

RA-L 2025

In pursuit of effective robot-assisted rehabilitation, it is imperative that the robot facilitates rather than hinders the patient's self-movements in appropriate directions. This essential attribute, termed <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/x

Enabling passivity for Cartesian workspace restrictions

ICRA 2024poster

An emerging trend in the field of human-robot collaboration is the disassembly of end-of-life products. Safety is a crucial requirement of the disassembly process since worn-out or damaged products could break, possibly resulting in dangerous behavior of the robot. To protect the user from such beha…

An Energy-based Approach for the Integration of Collaborative Redundant Robots in Restricted Work Environments

IROS 2020poster

To this day, most robots are installed behind safety fences, separated from the human. New use-case scenarios demand for collaborative robots, e.g. to assist the human with physically challenging tasks. These robots are mainly installed in work-environments with limited space, e.g. existing producti…

Geometrical Interpretation and Detection of Multiple Task Conflicts using a Coordinate Invariant Index

IROS 2020poster

Modern robots act in dynamic and partially unknown environments where path replanning can be mandatory if changes in the environment are observed. Task-prioritized control strategies are well known and effective solutions to ensure local adaptation of robot behaviour. The highest priority in a stack…
