One-step fast calibration of an industrial workcell

The calibration of a work cell is a process which allows to increase the accuracy of an industrial robot in reaching Cartesian locations. This is a crucial aspect if the robotic manipulator is required to perform accurate positioning to non-recorded locations or has to interact with external equipment. The calibration of a work cell is a time-consuming task and has to be repeated several times during set-up and every time the robot, equipment or sensors are moved from their original position for some reason, like maintenance. In this paper, a multi-calibration device and procedure are presented, which allow calibrating a picking plane with a one-step fast data acquisition procedure.
