A new flexible parts feeding system has been designed and constructed at Case Western Reserve University. To complement the feeder, an object-oriented software architecture has been designed and implemented. Design goals of the software were the ability to rapidly introduce a new part into the system without major reprogramming and the creation of a software architecture that would be applicable to the general class of visionbased parts feeders (rather than just our own implementation). The system currently feeds two different types of parts and can switch on-the-fly between part types. Throughputs in excess of 60 parts per minute have been achieved during testing.
