Abstract
A system for singulating objects includes a bin for receiving a collection of objects, a robotic manipulator for grasping objects from the bin, a scale for measuring a weight of the grasped objects, and a computer system for comparing measured weights to acceptable weight ranges to detect double picks. Methods include determining acceptable weight ranges by weighing a plurality of objects.
Claims6
A method of singulating objects from a collection of objects, comprising:
- determining an acceptable range of weights by weighing a plurality of individual objects having a specified characteristic and determining an average of weights of the plurality of individual objects and a statistical variance in the weights of the plurality of individual objects;
- receiving the collection of objects;
- using a robotic manipulator to pick up at least one object from the collection of objects;
- measuring a weight of the at least one object picked up by the robotic manipulator;
- determining that the at least one object picked up by the robotic manipulator has the specified characteristic;
- comparing the measured weight to the acceptable range of weights;
- determining, based on the comparison, whether or not the at least one object was successfully singulated;
- and
- depositing the at least one object into a container.
