چکیده

We describe a one-joint planar arm which repeatedly throws and catches parts on its surface, and we demonstrate that proper choice of the throw velocity and arm geometry guarantees that the part will enter a unique recurrent motion pattern from a large set of initial configurations. The resulting system resembles an open-loop stable juggler of polygonal parts.

Stable limit sets in a dynamic parts feeder

| We describe a one-joint planar arm which repeatedly throws and catches parts on its surface, and we demonstrate that proper choice of the throw velocity and arm geometry guarantees that the part will enter a unique recurrent motion pattern from a large set of initial con gurations. The resulting system resembles an open-loop stable juggler of polygonal parts. Combined with a simple one-bit se...

A comparison of real and simulated designs for vibratory parts feeding

The design of industrial parts feeders is a long, trial-anderror process that can take months – even for the design of feeders that orient only one type of part. This paper describes the use of dynamic simulation to expedite the design and prototyping of parts feeders. We give probabilistic descriptions of vibratory parts feeding behavior, and we present a comparison between simulated design ex...

Designing parts feeders using dynamic simulation

We consider the problem of designing traditional (e.g. vibratory bowl) feeders for singulating and orienting industrial parts. Our ultimate goal is to prototype new designs using analyticallyand geometrically-based methods. We have developed a tool for designing industrial parts feeders based on dynamic simulation. Our tool allows us to automatically perform multiple feeder design experiments, ...

Design Veri cation and Optimization of Novel Parts Feeders with the Impulse Dynamic Simulator

The Impulse dynamic simulator is used to generate a wide range of synthetic measurements for both a MEMsand a longitudinally-vibrating parts feeders. Impulse allows the devices' mechanics to be modeled in detail and for results to be generated both accurately and e ciently. Obtaining such results experimentally is impractical given the number of moving parts, small dimensions, and/or complexity...

The Complexity of Sensing by Point Sampling

In assembly tasks it is often necessary to recognize parts arriving via a conveyor belt or a parts feeder at some robot work cell. Generally the parts feeder will have reduced the number of possible poses of the parts to a small nite set. In order to distinguish between the remaining poses of the parts some simple sensing or probing operation may be used. In this paper we consider the problem o...
