Service robots and innovation: An ecosystem approach

Journal of Product Innovation Management, Volume 42, Issue 5, Page 874-896, September 2025.
Abstract The proliferation of service robots has stimulated innovation across industries. These autonomous, physically embodied, and adaptable robots engage in diverse interactions, from patient care to goods delivery and hospitality services. However, the deployment of increasingly capable service robots demands not only designing user–robot ...

Neuro‐Observer Based Adaptive Fixed‐Time Fault‐Tolerant Control for Uncertain Teleoperation System With Input Saturation and Asymmetric Time‐Varying Output Constraints

International Journal of Robust and Nonlinear Control, Volume 35, Issue 11, Page 4536-4553, 25 July 2025.
ABSTRACT The issue of master‐slave synchronization tracking control for uncertain teleoperation systems with input saturation and asymmetric time‐varying output constraints under actuator failure is investigated. Firstly, a neural network‐based nonlinear disturbance observer is designed to mitigate the negative impact of the compound uncertainty ...

A passive convex optimal control algorithm for teleoperating a redundant robotic arm in minimally invasive surgery

International Journal of Robust and Nonlinear Control, Volume 35, Issue 10, Page 4132-4148, 10 July 2025.
Abstract In recent years, the remote center of motion (RCM) constraint has moved from purely mechanical to software implementation, enabling the use of serial manipulators in robotic‐assisted minimal invasive surgery. However, ensuring safety with software‐based RCM presents challenges.

Hand controller for bilateral teleoperation of robots

Robotica, 2000
Teleoperation, one of the oldest areas of robotics, has experienced considerable growth in the last two decades. Main causes for this trend are the need for increased safety levels for human operators and lower production costs. In this work, a three d.o.f. local manipulator (two d.o.f. for force and one d.o.f.
