A robot's joint rates increase when passing near-singular kinematic setups, increasing the required axes currents and wearout of the bearings. Exceeding a manipulator's axes acceleratory limits will abort its motion and therefore make an off-line-planned trajectory undriveable in a real setting; Latter also applies to hitting the axes' angular constraints. Given a desired trajectory and aiming for...
In robotic contour-following tasks, such as sewing or cutting, an industrial robot guides a tool along the contour of a workpiece. Manually teaching the robot is time consuming and results in a system that is unable to react to uncertainties or changes in the environment. Because the cost effectiveness of a robotic solution depends on the amount of human intervention, particularly small series production...
In robotic contour following tasks such as sewing or cutting an industrial robot guides a tool along a contour of a workpiece. Teaching the task manually is very time consuming and the process would be unable to react to uncertainties or changes of the environment. Thus sensor systems are applied to reduce human intervention, making the robot more autonomous. In this paper we present an integrated...
In robotic contour following tasks such as sewing, grinding or applying adhesives, the robot moves a tool along a desired path on a workpiece. In order to compensate inaccuracies of the path definition a vision system can be used to guide the robot during task execution. This paper presents an algorithm to adjust the position and orientation of the tool by predictive vision-based control that compensates...
