Excerpt from Robotics Research Technical Report: On the Number of Critical Free Contacts of a Convex Polygonal Object Moving in 2-D Polygonal Space
We show that the number of critical positions of a convex polygonal object moving amidst polygonal barriers in two dimensional space, at which it makes three simultaneous contacts with the obstacles but does not penetrate into any obstacle is for some s s 6, where k is the number of boundary segments of B, n is the number of wall segments and x,(q) is an almost linear function of q yielding the maximal number of connected graph portions composing the lower envelope of a set of q continuous functions each pair of which intersect in at most s points. We also present an example where the number of such critical contacts is Q(k2n showing that m the worst case our upper bound is almost Optimal.

Paperback. Condition: New. Print on Demand. This book explores a specific geometry problem in the field of computer science involving the movement of objects within confined spaces. The author presents an analysis of the number of critical positions in which a convex polygonal object can make simultaneous contact with three obstacles while remaining free, meaning it does not penetrate any obstacle. Through mathematical proofs and an illustrative example, the book provides an insightful upper bound on the number of such critical positions. The author's analysis finds that the number of critical positions is dependent on the number of sides of the polygon and the number of obstacles, which is significant for designing efficient algorithms that enable collision-free motion planning for polygonal objects.
