... 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...

... composed of m subrobots can be expressed as: Multirobot Optical processing Adaptive fuzzy Control strategy Error compensation By using evolving technology, modern optical mirrors are being developed with increased apertures and enhanced precision. Their fabrication has high...

... calibration) and a calibration pattern. The method is applied to a pick-and-place scenario using an industrial robot. Online error compensation is a further possibility, which uses servoing techniques (most commonly visual servoing) to improve accuracy (Jiang et al., 2016). Robot calibration can...

...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...
