Jog Arm

Quick Start Guide for UR5 example

Clone the universal_robot repo into your catkin workspace:

git clone https://github.com/ros-industrial/universal_robot.git

Run rosdep install from the src folder to install dependencies.

rosdep install --from-paths . --ignore-src -y

Build and subsequently source the catkin workspace. Startup the robot and MoveIt:

roslaunch ur_gazebo ur5.launch

roslaunch ur5_moveit_config ur5_moveit_planning_execution.launch sim:=true

roslaunch ur5_moveit_config moveit_rviz.launch config:=true

In RViz, "plan and execute" a motion to a non-singular position (not all zero joint angles) that is not close to a joint limit.

Switch to a compatible type of ros-control controller. It should be a JointGroupVelocityController or a JointGroupPositionController, not a trajectory controller like MoveIt usually requires.

rosservice call /controller_manager/switch_controller "start_controllers:
- 'joint_group_position_controller'
stop_controllers:
- 'arm_controller'
strictness: 2"

Launch the jog node. This example uses commands from a SpaceNavigator joystick-like device:

roslaunch moveit_jog_arm spacenav_cpp.launch

If you dont have a SpaceNavigator, send commands like this:

rostopic pub -r 100 /jog_server/delta_jog_cmds geometry_msgs/TwistStamped "header: auto
twist:
  linear:
    x: 0.0
    y: 0.01
    z: -0.01
  angular:
    x: 0.0
    y: 0.0
    z: 0.0"

If you see a warning about "close to singularity", try changing the direction of motion.

Running Tests

Run tests from the jog_arm folder:

catkin run_tests --no-deps --this
