While motion planning for simple robots (such as the S-bot
robot) can be successfully solved by the RRT-K method (or even
by the RRT-CPG method), the planning of more complex robots
e.g. Lizards or Quadropods, should rather be solved using RRT-MP.
The proposed RRT-MP algorithm has been evaluated as the most
effective for modular robots in general, since the possibility to form
complex bodies is property embodied in them.
