Detailed Description

Description of the ::P3D_TRANSLATE joint.

It's one of the basic joint in Move3D. This is a single translation joint. It's default orientation is the z axis (modified by pos in p3d_jnt_translate_create()).

Function Documentation

void p3d_jnt_translate_calc_jnt_mat ( p3d_jnt * jntPt )

Compute the transformation matrix of the joint.

This function use the value for the degree of freedom set in the joint by p3d_jnt_set_dof(). This is a translation on z axis. This is used in p3d_jnt_calc_mat_pos() for ::P3D_TRANSLATE joint.

Parameters:

jntPt,: the joint

void p3d_jnt_translate_calc_mat_jac ( p3d_jnt * jntPt )

Compute the jacobian matrix of the joint.

This function use the value for the degree of freedom set in the joint by p3d_jnt_set_dof(), the position matrix and the prejacobian matrix of the previous joint. This is used in p3d_jnt_calc_mat_pos() for ::P3D_TRANSLATE joint.

Parameters:

jntPt,: the joint

p3d_jnt* p3d_jnt_translate_create	(	p3d_matrix4	pos,
		double *	v,
		double *	vmin,
		double *	vmax,
		double *	vmin_rand,
		double *	vmax_rand,
		double *	velocity_max,
		double *	acceleration_max,
		double *	jerk_max,
		double *	param
	)

Create a new joint ::P3D_TRANSLATE.

Parameters:

pos,:	the position matrix of the joint
v,:	the values of the degree of freedom for the joint
vmin	& vmax: the bounds values of the degree of freedom for the joint
vmin_rand	& vmax_rand: the random (or user) bounds values of the degree of freedom for the joint
param,:	the array of the parameters for the joint (NULL here)

Returns:: the new joint.

const char* p3d_jnt_translate_get_dof_name ( int i_dof )

Get the name of a degree of freedom for a translate joint.

This is the implementation of p3d_jnt_get_dof_name() for the joint ::P3D_TRANSLATE.

Parameters:

i_dof,: the index of the degree of freedom

Returns:: The name of the degree of freedom

void p3d_jnt_translate_stay_within_dist	(	p3d_stay_within_dist_data *	prev_data,
		p3d_jnt *	jntPt,
		p3d_stay_within_dist_data *	data,
		double *	distance,
		configPt	q_init,
		configPt	q_max_param,
		double	max_param,
		double *	reach_param
	)

Compute the distance and the speed that the joint could reach.

From the configuration q_init of the joint to q_max_param, this function computes an interval of parameter which all the points of the joint move by less than the distance given as input. This is the implementation of p3d_jnt_stay_within_dist() for the joint ::P3D_TRANSLATE.

Note: The joint looks directly in the robot configurations the degree of freedom that it needs.

Parameters:

prev_data,:	speed of the previous joint
jntPt,:	the joint
distance,:	the maximal distance
qinit,:	the initial configuration
q_max_param,:	the final configuration
max_param,:	the value of the delta parameter in the final configuration (it gives the range param needed to reach the final configuration)
reach_param,:	the actual maximal parameter that could be reach (previous joint can limits the range parameter)

Return values:

data,: speed of the joint distance: the distance that the joint couldn't cross reach_param: the new maximal range parameter that could be reach

void p3d_jnt_translate_stay_within_sphere	(	p3d_stay_within_dist_data *	prev_data,
		p3d_jnt *	jntPt,
		p3d_stay_within_dist_data *	data,
		double *	distance,
		double *	reach_param
	)

Compute the distance and the speed that the joint could reach.

This function computes an interval of parameter which all the points of the joint move by less than the distance given as input. This is the implementation of p3d_jnt_stay_within_sphere() for the joint ::P3D_TRANSLATE.

Note: The joint looks directly in the robot configurations the degree of freedom that it needs.

Parameters:

prev_data,:	speed of the previous joint
jntPt,:	the joint
distance,:	the maximal distance

Return values:

data,: speed of the joint distance: the distance that the joint couldn't cross reach_param: the new maximal range parameter that could be reach
