def hpp.corbaserver.robot.Robot.getJointConfigSize	(		self,
			jointName
	)

Get joint number config size.

def hpp.corbaserver.robot.Robot.getJointInnerObjects	(		self,
			jointName
	)

Get the list of objects attached to a joint.

Parameters

inJointName

name of the joint.

Returns

list of names of CollisionObject attached to the body.

def hpp.corbaserver.robot.Robot.getJointNames

(

self

)

Get joint names in the same order as in the configuration.

def hpp.corbaserver.robot.Robot.getJointNumberDof	(		self,
			jointName
	)

Get joint number degrees of freedom.

def hpp.corbaserver.robot.Robot.getJointOuterObjects	(		self,
			jointName
	)

Get list of collision objects tested with the body attached to a joint.

Parameters

inJointName

name of the joint.

(

self

)

Get the aligned axes bounding box around the robot.

Returns

a vector a 6 floats. The 3 first are one corner of the box (lowest in all dimensions), the 3 last are the opposite corner.

def hpp.corbaserver.robot.Robot.getRootJointPosition

(

self

)

Get constant position of root joint in world frame in initial position.

def hpp.corbaserver.robot.Robot.getSaturated	(		self,
