... are conducted for validation. Findings After geometric error compensation, the maximum absolute positioning error, mean error and root mean square error of the robotic arm end-effector are reduced by 70.77%, 70.95% and 69.78%, respectively. Field experiments confirm that the calibrated robot can stably...

..., for mobile robots to address the problem of estimating the required driving torque with unknown terrain disturbances. Design/methodology/approach An error compensation (EC) framework is used, and the preliminary prediction driving torque value is achieved using Gaussian process regression (GPR...

... to compensate for the motion control accuracy of a hydraulically driven legged robot. Chen et al. (2019) proposed a hybrid error compensation method to correct the positioning and trajectory errors of a series robot. For a modular reconfigurable robot with an actuator fault, Xia and Guo (2021...

...Guanhua Li; Wei Dong Zhu; Huiyue Dong; Yinglin Ke Purpose This paper aims to present error compensation based on surface reconstruction to improve the positioning accuracy of industrial robots. Design/methodology/approach In previous research, it has been proved that the positioning error...

... that, Kriging equations are determined and solved to predict the position errors of targets. Subsequently, a simple and convenient error compensation, which can be implemented on the control command, is proposed. Findings The verification experiment of the position-error multiplicity and the Kriging...

... and parameter identification is proposed based on double ball-bar (DBB) measurements. The measurement trajectory is determined by the motion characteristics of this mechanism and whether the error sources can be identified. Error compensation is proposed by modifying the inputs, and a two-step kinematic...
