Abstract
One embodiment provides a robotic system comprising: a robot, the robot further comprising a moveable robotic arm that moves within the robot's reference space; a depth-sensing camera, the camera having a reference frame that is in substantial view of the robot's reference space; a controller, the controller further comprising a processor and a computer readable memory that comprises instructions such that, when read by the controller, the controller inputs image data from the camera and sends signals to the moveable robotic arm, the instructions further comprising the steps of: calibrating the camera to the robot by instructing the robot to engage in a number of robot poses; extracting the location of the robot poses to obtain the robot poses in the camera reference frame; and creating a transformation that transforms robot points afterwards to camera points.
