The vibratory bowl feeder remains the most common approach to the automated feeding (orienting) of industrial parts. We study the algorithmic design of devices on the bowl feeder track that filter out all but one orientation of a given polyhedral part. In this context, we propose a simple new primitive, consisting of one horizontally mounted convex(More)
The vibratory bowl feeder remains the most common approach to the automated feeding (orienting) of industrial parts. We study the algorithmic design of a trap in the bowl feeder track that filters out all but one orientation of a given polygonal part. We propose a new class of traps that we call guillotine traps, which remove a portion of the track between(More)
The "blade", a three-parameter primitive for part feeding, and a complete (quasi-static) algorithm for its design (which runs in O(n<sup>6</sup>) time) were introduced. Here, we present our implementation of the geometric blade design algorithm, a reconfigurable modular blade hardware design, and physical experiments: we report experiments with 14 blade(More)
In the context of automated feeding (orienting) of industrial parts, we study the algorithmic design of traps in the bowl feeder track that filter out all but one orientation of a given polyhedral part. We propose a new class of traps that removes a V-shaped portion of the track. The proposed work advances the state-of-the-art in algorithmic trap design by(More)
