Kiwicjam | 0:da791f233257 | 13 | * This class keeps the motion values <code>position</code> and <code>velocity</code>, and |
Kiwicjam | 0:da791f233257 | 14 | * offers methods to increment these values towards a desired target position or velocity. |
Kiwicjam | 0:da791f233257 | 15 | * <br/> |
Kiwicjam | 0:da791f233257 | 16 | * To increment the current motion values, this class uses a simple 2nd order motion planner. |
Kiwicjam | 0:da791f233257 | 17 | * This planner calculates the motion to the target position or velocity with the various motion |
Kiwicjam | 0:da791f233257 | 18 | * phases, based on given limits for the profile velocity, acceleration and deceleration. |
Kiwicjam | 0:da791f233257 | 19 | * <br/> |
Kiwicjam | 0:da791f233257 | 20 | * Note that the trajectory is calculated every time the motion state is incremented. |
Kiwicjam | 0:da791f233257 | 21 | * This allows to change the target position or velocity, as well as the limits for profile |
Kiwicjam | 0:da791f233257 | 22 | * velocity, acceleration and deceleration at any time. |
