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…

A Power-Aware Control Strategy for an Elbow Effort-Compensation Device

RA-L 2023

This work presents a reactive control strategy for loading and sudden unloading of an elbow effort-compensation device controlled in force. Through this control strategy, in addition to an individual's forearm weight, an external load can be detected and adaptively compensated via a feed-forward for

Design of an Energy-Aware Cartesian Impedance Controller for Collaborative Disassembly

ICRA 2023poster

Human-robot collaborative disassembly is an emerging trend in the sustainable recycling process of electronic and mechanical products. It requires the use of advanced technologies to assist workers in repetitive physical tasks and deal with creaky and potentially damaged components. Nevertheless, wh…

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…
