Claim 14:
15. A robotic picking system comprising:
a robotic arm;
a picking assembly coupled to the robotic arm, the picking assembly comprising a housing having a first flat surface and a second flat surface;
a first calibration pattern disposed on the first flat surface of the housing;
a second calibration pattern disposed on the second flat surface of the housing;
a first camera configured to image the first calibration pattern and the second calibration pattern; and
a controller configured to calibrate the robotic picking system by:
causing the robotic manipulator to move to a first predetermined position;
determining first position data associated with a pose of the robotic manipulator at the first predetermined position;
determining, using the first camera, a first image of the first calibration pattern when the robotic manipulator is at the first predetermined position; and
determining a first calibration adjustment based at least in part on the first position data and the first image, wherein the first calibration adjustment includes an adjustment to at least one coordinate associated with the first predetermined position, and wherein the adjustment causes a change in physical position.
