Abstract:Algorithms, theoretical analysis, and practical examples (as applicable) are presented for three main problems, and several variations thereon. First, the problem of a fully actuated point robot moving in a piecewise linear environment of arbitary dimension is addressed. Second, fully actuated robots with bodies are considered---both practical problems like planar disc or polygonal robots, and the fully general case of a semi-algebraic robot moving amidst semi-algebraic obstacles (the generalized piano mover's problem). Third, feedback plans for point robots with simple nonholonomic constraints, such as unicycles and car-like robots, are described. Each of these problems is addressed using variations on a unified approach. First, the environment is decomposed into simple (often convex) cells; second, local vector fields are created and combined together to create a solution to the global navigation problem. In addition to standard navigation problems, approaches to trajectory tracking and multiple robot coordination are described to illustrate the flexibility of the approach.
