# robot_type: xarm/lite/uf850
# dof: 
#   robot_type=xarm: dof=5/6/7
#   robot_type=lite/uf850: dof=6

  • Call Service for planning (here take xarm7 as an example)

    • For joint-space planning request:

      rosservice call xarm_joint_plan 'target: [1.0, -0.5, 0.0, -0.3, 0.0, 0.0, 0.5]'

      The target elements in this case correspond to each joint target angle in radians, number of elements is same with the DOF.

    • For Cartesian-space point-to-point planning request:

      rosservice call xarm_pose_plan 'target: [[0.28, 0.2, 0.2], [1.0, 0.0, 0.0, 0.0]]'

      The separated fields for Cartesian target correspond to tool frame position (x, y, z) in meters and orientation Quaternions (x, y, z, w). Note that this motion is still point-to-point, meaning the trajectory is NOT a straight line.

    • For Cartesian straight line planning request:

      rosservice call xarm_straight_plan 'target: [[0.28, 0.2, 0.2], [1.0, 0.0, 0.0, 0.0]]'

      Command data units are the same with above Cartesian pose command. If planned succesfully, end-effector trajectory will be a straight-line in space. Note that the velocity change may not be as expected during execution. Please refer to MoveGroupInterface documentation to make your modifications to the code if necessary.

      After calling the above planning services, a boolean result named 'success' will be returned.

  • For Execution of planned trajectory:

    Notice: Use Cartesian planning with special care, since trajectory from Moveit (OMPL) planner can be highly random and not necessarily the optimal (closest) solution, Do check it in Rviz befroe confirm to move!

    If solution exists and user want to execute it on the robot, it can be done by service call (recommended) or topic message.

    • Execute by service call (Blocking)

      Call the 'xarm_exec_plan' service with a request data of 'true', the latest planned path will be executed, the service will return after finishing the execution:

      rosservice call xarm_exec_plan 'true'

    • Execute by topic (Non-blocking)

      Just publish a message (type: std_msgs/Bool) to the topic "/xarm_planner_exec", the boolean data should be 'true' to launch the execution, it returns immediately and does not wait for finish:

      rostopic pub -1 /xarm_planner_exec std_msgs/Bool 'true'

Optional Parameters

  • General parameters

    • model1300: Whether it is a 1300 model, it is only valid for the xarm series, mainly because the end model has changed, if robot_sn is specified, it will automatically override this parameter according to the SN

    • limited: Whether to limit the joint range to (-180, 180), the default is true

    • attach_to: The link name of the robotic arm attach, the default is world (this name will create a link by default)

    • add_gripper: Whether to load the gripper, the default is false, the priority is higher than add_vacuum_gripper and add_other_geometry

    • add_vacuum_gripper: Whether to load the vacuum gripper, the default is false, the priority is lower than add_gripper, but higher than add_other_geometry

    • add_other_geometry: Whether to add other geometry models to the end, the default is false, the priority is lower than add_gripper and add_vacuum_gripper

      • geometry_type: The type of geometric model to be loaded supports box/cylinder/sphere/mesh, and the parameters supported by different types are different

      • geometry_width: Geometry model width, unit (meter), default 0.1, only valid when geometry_type is box

      • geometry_mesh_filename: The file name of the geometric model, geometry_type is valid for mesh, the file needs to be stored under the xarm_description/meshes/other/ directory, so that there is no need to specify the file directory in the file name

      • geometry_mesh_origin_xyz: The datum reference system of the geometric model is relative to the reference system of the end flange. The geometry_type is mesh and valid. Pay attention to the quotation marks when using: geometry_mesh_origin_xyz:='"0.0 0.0 0.0"'

      • geometry_mesh_tcp_rpy: The offset of the end of the geometric model (TCP) relative to the reference frame of the geometric model, valid when geometry_type is mesh. Pay attention to the quotation marks when using: geometry_mesh_tcp_rpy:='"0.0 0.0 0.0"'

    • jnt_stat_pub_rate: Publish frequency of joint_state_publisher, default is 10

  • Special parameters

    • hw_ns: Namespace, xarm series defaults to xarm, others default to ufactory, only valid in gazebo/realmove startup scripts, the corresponding service name is <hw_ns>/<service_name>

    • velocity_control: Whether to use speed control, only valid in gazebo/realmove startup script, default is false

    • report_type: The report type supports normal/dev/rich, and the default is normal, which is only valid in the realmove startup script. It decides the state feedback rate and content. Refer to the developer manual at chapter 2.1.6 Automatic Reporting Format for the report contents of the three available report type (normal/rich/dev), default type using is "normal".

      • For users who demand high-frequency feedback, report_type:=dev can be specified, then the topics /<hw_ns>/xarm_states and /<hw_ns>/joint_states will be published at 100Hz.

      • For users who want the gpio states being updated at /<hw_ns>/controller_gpio_states topic, please use report_type:=rich, since this reports the fullest information from the controller. As can be seen in developer manual.

      • The report rate of the three types:

        Note: GPIO topic => <hw_ns>/controller_gpio_states. F/T sensor topic => <hw_ns>/uf_ftsensor_ext_states and <hw_ns>/uf_ftsensor_raw_states。
