چکیده
We have designed and implemented multi-agent strategies for manipulation tasks by distributing mechanically-based sequential algorithms across several autonomous spatially-separated agents, such as mobile robots. Our experience using mobile robots for the manipulation of large objects (couches, boxes, le cabinets, etc.) leads us to recommend a minimalist architecture for multi-agent programming. In particular , our methodology has led us to derive asynchronous distributed strategies that require no direct communication between agents, and very sparse geometric and dynamic models of the objects our robots manipulate. We argue for a design principle called supermodu-larity, which is orthogonal both to the notion of modu-larity in cognitive AI and also to horizontal decomposition (the non-modularity advocated in the subsump-tion/connectionist literature.) Finally, we discuss a simple mobot-Scheme infrastructure to implement supermodular architectures. In the past few years we have programmed many su-permodular manipulation protocols and tested them extensively on our team of mobile robots. We describe why we think the supermodular infrastructure results in robust, simple, readable, manipulation strategies that can be recycled and reused.

Con gurable computers have attracted considerable attention recently because they promise to deliver the performance of application-speci c hardware along with the exibility of general-purpose computers. Unfortunately, con gurable computing has had rather limited success to date. We believe that the FPGAs currently used to construct con gurable computers are too general to achieve good cost-per...
