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