other; if they do, they are considered one obstacle. The total number of obstacles in the scene need not be nite. The robot s sensors provide it with information about its surroundings within the sensing range (radius of vision), a disc of radius rv centered at its current location Ci . The sensor can assess the distance to the nearest obstacle in any direction within the sensing range. The robot input information at moment ti includes its current velocity vector Vi , coordinates of point Ci and of the target point T , and possibly few other points of interest that will be discussed later. The task is to move, collision-free, from point S (start) to point T (target) (see Figure 4.1). The robot s control means include two components (p, q) of f the acceleration vector u = m = (p, q), where m is the robot mass and f is the force applied. Though the units of (p, q) are those of acceleration, by normalizing to m = 1 we can refer to p and q as control forces, each within its xed range |p| pmax , |q| qmax . Force p controls forward (or backward when braking) motion; its positive direction coincides with the velocity vector V. Force q is perpendicular to p, forming a right pair of vectors, and is equivalent to the steering control (rotation of vector V) (Figure 4.2). Constraints on p and q imply a constraint on the path curvature. The point mass assumption implies that the robot s rotation with respect to its center of mass has no effect on the system dynamics. There are no external forces acting on the robot except p and q. There is no friction; for example, values p = q = 0 and V = 0 will result in a straight-line constant velocity motion.2 Robot motion is controlled in steps i, i = 0, 1, 2, . . . . Each step takes time t = ti+1 ti = const. The step s length depends on the robot s velocity within

the step. Steps i and i + 1 start at times ti and ti+1 , respectively; C0 = S. While moving toward location Ci+1 , the robot computes necessary controls for step i + 1 using the current sensory data, and it executes them at Ci+1 . The nite time necessary within one step for acquiring sensory data, calculating the controls, and executing the step must t into the step cycle (more details on this can be found in Ref. 96). We de ne two coordinate systems (follow Figure 4.2):

The world coordinate frame, (x, y), xed at point S. The path coordinate frame, (t, n), which describes the motion of point mass at any moment [ti , ti+1 ) within step i. The frame s origin is attached to the robot; axis t is aligned with the current velocity vector V; axis n is normal to t; that is, when V = 0, the frame is unde ned. One may note that together with axis b = t n, the triple (t, n, b) forms the known Frenet trihedron, with the plane of t and n being the osculating plane [97].

4.2.2 Sketching the Approach Some terms and de nitions here are the same as in 3; material in Section 3.1 can be used for more rigorous de nitions. De ne M-line (Main line) as the straight-line segment (S, T ) (Figure 4.1). The M-line is the robot s desired path. When, while moving along the M-line, the robot senses an obstacle crossing the M-line, the crossing point on the obstacle boundary is called a hit point, H . The corresponding M-line point on the other side of the obstacle is a leave point, L. The planning procedure is to be executed at each step of the robot s path. Any provable maze-searching algorithm can be used for the kinematic part of the algorithm that we are about to build, as long as it allows distant sensing. For speci city only, we use here the VisBug algorithm (see Section 3.6; either VisBug-21 or VisBug-22 will do). VisBug algorithms alternate between these two operations (see Figure 4.1): 1. Walk from point S toward point T along the M-line until, at some point C, you detect an obstacle crossing the M-line, say at point H .
