Abstract:
A method for calibrating an articulable end effector of a robotic arm employing a digital camera includes commanding the end effector to achieve a plurality of poses. At each commanded end effector pose, an image of the end effector with the digital camera is captured and a scene point cloud including the end effector is generated based upon the captured image of the end effector. A synthetic point cloud including the end effector is generated based upon the commanded end effector pose, and a first position of the end effector is based upon the synthetic point cloud, and a second position of the end effector associated with the scene point cloud is determined. A position of the end effector is calibrated based upon the first position of the end effector and the second position of the end effector for the plurality of commanded end effector poses.
