A robot is free to move in a non-convex polygonal region , starting against an edge on the boundary. Ahead of the robot at one unit of distance is a corner, i.e. a reflex vertex (see Figure 1). The angle θ is unknown to the robot. The robot's task is to look at the region around the corner, which it initially cannot see. We let ϕ = π − θ. If ϕ ≥ π/2, the(More)
