void position_init

(

struct robot_position *

pos

)

initialization of the robot_position pos, everthing is set to 0

		int16_t	y,
		int16_t	a
	)

Set a new robot position

		double	distance_imp_per_cm
	)

Set the physical parameters of the robot :

• number of impulsions for 1 cm (distance)
• number of impulsions for 1 degree (angle)

void position_set_related_robot_system	(	struct robot_position *	pos,
		struct robot_system *	rs
	)

Save in pos structure the pointer to the associated robot_system. The robot_system structure is used to get values from virtual encoders that return angle and distance.
