A kinematic parameter calibration method for industrial robot based on a novel designed 3D ballbar device

The limited positioning accuracy of industrial robots restricts their application in high-precision manufacturing. Existing calibration methods based on coordinate measuring machines or laser trackers provide high accuracy but require expensive equipment, complex setup, and are inconvenient for on-site applications. Co...

A comparative study on the accuracy&repeatability of mobile robotic platforms for the delivery of precision NDE measurement

Mobile robotic platforms offer a flexible alternative to fixed manipulators for non-destructive evaluation (NDE) of large aerospace structures, but their base-positioning accuracy and how that accuracy should inform deployment have not been assessed under a common, externally referenced protocol. This work presents a l...

A Simultaneous Calibration Method for Dual-Arm Robots Based on Optical Trackers

This paper presents a unified calibration method for the full parameters of the dual-arm robotic system, encompassing hand-eye, kinematic, and tool center point (TCP) parameters. Firstly, the closed-loop equation, AXP=YCQ, is established in three-dimensional space and solved by neglecting kinematic parameter errors, th...

Two-Dimensional, Vision-Based Measurement for Experimental Characterization of Planar Compliant Mechanisms: A Critical Review and Uncertainty-Aware Framework

In planar compliant mechanisms, single-input dual-output (SIDO) displacement amplifiers driven by piezoelectric actuators are frequently used in precision positioning, micro/nano manipulation, and biomedical microdevices. Accurate experimental verification of these mechanisms remains challenging because traditional con...
