Constructor & Destructor Documentation

DynamicsSolver()

dynamics_solver::DynamicsSolver::DynamicsSolver	(	const moveit::core::RobotModelConstPtr &	robot_model,
		const std::string &	group_name,
		const geometry_msgs::msg::Vector3 &	gravity_vector
	)

Initialize the dynamics solver.

Parameters

urdf_model	The urdf model for the robot
srdf_model	The srdf model for the robot
group_name	The name of the group to compute stuff for

Returns

False if initialization failed

getMaxPayload()

bool dynamics_solver::DynamicsSolver::getMaxPayload	(	const std::vector< double > &	joint_angles,
		double &	payload,
		unsigned int &	joint_saturated
	)		const

Get the maximum payload for this group (in kg). Payload is the weight that this group can hold when the weight is attached to the origin of the last link of this group. (The order of joint_angles vector is the same as the order of joints for this group in the RobotModel)

Parameters

joint_angles	The joint angles (desired joint configuration) this must have size = number of joints in the group
payload	The computed maximum payload
joint_saturated	The first saturated joint and the maximum payload

Returns

False if the input set of joint angles is of the wrong size

bool dynamics_solver::DynamicsSolver::getPayloadTorques	(	const std::vector< double > &	joint_angles,
		double	payload,
		std::vector< double > &	joint_torques
	)		const

Get torques corresponding to a particular payload value. Payload is the weight that this group can hold when the weight is attached to the origin of the last link of this group.

Parameters

joint_angles	The joint angles (desired joint configuration) this must have size = number of joints in the group
payload	The payload for which to compute torques (in kg)

		std::vector< double > &	torques
	)		const

Get the torques (the order of all input and output is the same as the order of joints for this group in the RobotModel)

Parameters
