class
#include <BipedalLocomotion/TSID/SO3Task.h>
SO3Task SO3Task is a concrete implementation of the TSIDLinearTask.
Please use this element if you want to control the orientation of a given frame rigidly attached to the robot. The task assumes perfect control of the robot acceleration that contains the base linear and angular acceleration expressed in mixed representation and the joints acceleration. The task represents the following equation
where is the robot jacobian and is the desired acceleration. The desired acceleration is chosen such that the frame orientation will asymptotically converge to the desired trajectory. The angular acceleration is computed by a PD controller in .
Base classes
- struct TSIDLinearTask
- TSIDLinearTask specializes a LinearTask in the case of Task based Inverse Dynamics.
