Detailed Description

Kino-dynamic straight path

This Path has the same behavior as the StraightPath class except for the translation part of the free-flyer. For the translation part of the free-flyer KinodynamicPath store a "bang-bang" trajectory dependent on time with either 2 segment of constant acceleration or 3 segments with a constant velocity segment

In current implementation, only the translation part of the freeflyer joint is considered by this class. The value of all other joint are interpolated between the initial and end value using the interpolate() method.

The current implementation assume that :

The first joint of the robot is a freeflyer
The robot have an extra Config Space of dimension >= 6. The first 3 values of the extraConfig are the velocity of the root and the 3 other values are the aceleration.
