Abstract
A robotic object handling system comprises a robot arm, a non-contact sensor, a first station, and a computing device. The computing device is to cause the robot arm to pick up an object on an end effector, cause the robot arm to position the object within a detection area of the non-contact sensor, cause the non-contact sensor to generate sensor data of the object, determine at least one of a rotational error of the object relative to a target orientation or a positional error of the object relative to a target position based on the sensor data, cause an adjustment to the robot arm to approximately remove at least one of the rotational error or the positional error from the object, and cause the robot arm to place the object at the first station, wherein the placed object lacks at least one of the rotational error or the positional error.
