Here is the call graph for this function:

◆ run()

void run	(	const Config &	cfg,
		ControlTarget &	targets
	)

run in rt thread

--------------------------— Impedance control ------------------------------------------— calculate pose error between target pose and current pose !!! This is very important: you have to keep postion and orientation both with UI unit (meter, radian) to calculate impedance force.

--------------------------— Nullspace PD Control -----------------------------------------------—

--------------------------— Map TS target force to JS -----------------------------------------------—

--------------------------— write torque target -----------------------------------------------—

Here is the call graph for this function:

◆ updateControlStatus()

bool updateControlStatus	(	const Config &	cfg,
		const RobotStatus &	robotStatus
	)

check size and value

--------------------------— get current status of robot ------------------------------------------— original data in ArmarX use the following units: position in mm, joint angles and orientation in radian, velocity in mm/s and radian/s, etc. here we convert mm to m, if you use MP from outside, make sure to convert it back to mm

--------------------------— keypoint related ------------------------------------------— compute (filtered) keypoint position

compute filtered keypoint velocity

--------------------------— compute keypoint tracking force ------------------------------------------—

in theory, we can also add s.desiredKeypointVelocity to the damping term
