after,
rosparam load /motoman_sda20d/urdf/motoman_sda20d.urdf robot_description
and
rosparam set controller_joint_names "[arm_left_joint_1_s, arm_left_joint_2_l, arm_left_joint_3_e, arm_left_joint_4_u, arm_left_joint_5_r, arm_left_joint_6_b, arm_left_joint_7_t, arm_right_joint_1_s, arm_right_joint_2_l, arm_right_joint_3_e, arm_right_joint_4_u, arm_right_joint_5_r, arm_right_joint_6_b, arm_right_joint_7_t, torso_joint_b1]"
How can I do the correct configuration?
