Abstract

A camera-based auto-alignment process can include gripping a first calibration tool by a gripper unit of a robotic arm. Images of the first calibration tool can be captured by a camera coupled to the gripper unit. The gripper unit and camera unit can be aligned on two roughly parallel axes. The images can be analyzed to calibrate the axis of view of the camera with the gripper axis, providing an XY calibration of the robotic arm. The gripper unit can be calibrated on a Z-axis using optical calibration with landmarks provided on a second calibration tool, and / or by moving the gripper unit towards the work surface until it makes contact with the work surface and stops. Once calibrated, the camera can be used to identify one or more landmarks at known locations on the work surface to align the robotic arm with the work surface.
