A Novel Robust Adaptive Impedance Control Scheme for Contact Force Tracking With Unknown Environment

RA-L 2025

Tracking desired force on various environmental surfaces is essential in many modern robotic applications. The constant impedance control (CIPC) has ability to realize this goal with clear environmental information (including stiffness and geometry), but failed when the information is not available.

A stepwise identification framework for determining the physical feasibility parameters of robot dynamics

IROS 2025

This paper introduces a systematic approach to identifying a physically feasible set of robot dynamics parameters. The framework consists of four steps: 1) Identification of robot dynamics parameters using least squares combined with a linear friction model. 2) Construction of a weighting matrix bas

An Efficient Linear Programming-Based Time-Optimal Feedrate Planning Considering Kinematic and Dynamics Constraints of Robots

RA-L 2024

This letter investigates the time-optimal trajectory generation for a six-degrees-of-freedom articulated robot moving along a given parametric path. In the generation procedure, besides the velocity, acceleration, and joint torque, the jerk is also constrained to enhance the smoothness of the robot'

One-Step Identification of Robot Physical Dynamic Parameters Considering the Velocity-Load Friction Model

RA-L 2024

We propose a robot dynamic model to improve the accuracy of the identification, by introducing a friction model that takes into account the joint loads. Firstly, we analyze torque transfer in robot joints, assigning a physical meaning to motor inertia parameters. Then, we enhance the traditional fri

A Robotic Manipulator Using Dual-Motor Joints: Prototype Design and Anti-Backlash Control

RA-L 2023

This letter focuses on the design and control of a novel seven-degree-of-freedom (7-DOF) robotic manipulator (D-Arm) to address the issue of backlash nonlinearity coupling unknown disturbance through the dual-motor anti-backlash control technology. Specifically, the first three axes of the D-Arm nea
