On-line self-calibration method for unattended manipulators based on Gaussian motion model and visual system

Qi, Ruolong; Tang, Yuangui; Zhang, Ke - In: Industrial Robot: the international journal of robotics … 48 (2021) 2, pp. 300-312

Purpose For some special manipulators such as the ones work at the space station, nuclear or some other unmanned environments, the overload, collision, vibration, temperature change or release of the internal stress would affect the structural parameters. And thus the operation precision might...
