Class #12: Nonholonomic Planning
________________________________________________________________________________________________________________

The car is a good example of a nonholonomic vehicle: it has only two controls, but its configuration space has dimension 3. The two drawings in the middle show nonholonomic paths between two obstacles. The rightmost drawing shows a car that can on turn left doing a parallel parking operation on its right side; many reversals are needed.

• Topics
  - Nonholonomic motion constraints
  - Motion planner for car-like robot using basic maneuvers
  - Transformation of holonomic path into a nonholonomic one
