ur_robot_driver

The new driver for Universal Robots UR3, UR5 and UR10 robots with CB3 controllers and the e-series.

Launchfiles

ur3e_bringup.launch

Standalone launchfile to startup a ur3e. This requires a robot reachable via a network connection.

Arguments

  • "controller_config_file" (default: "$(find ur_robot_driver)/config/ur3e_controllers.yaml")

    Config file used for defining the ROS-Control controllers.

    Kinematics config file used for calibration correction. This will be used to verify the robot's calibration is matching the robot_description.

    Names of the joints. Usually, this is given in the controller config file.

  • "headless_mode" (Required)

    Start robot in headless mode. This does not require the 'External Control' URCap to be running on the robot, but this will send the URScript to the robot directly. On e-Series robots this requires the robot to run in 'remote-control' mode.

  • "input_recipe_file" (Required)

    Path to the file containing the recipe used for requesting RTDE inputs.

  • "kinematics/hash" (Required)

    Hash of the calibration reported by the robot. This is used for validating the robot description is using the correct calibration. If the robot's calibration doesn't match this hash, an error will be printed. You can use the robot as usual, however Cartesian poses of the endeffector might be inaccurate. See the "ur_calibration" package on help how to generate your own hash matching your actual robot.

  • "output_recipe_file" (Required)

    Path to the file containing the recipe used for requesting RTDE outputs.

  • "reverse_port" (Required)

    Port that will be opened to communicate between the driver and the robot controller.

  • "robot_ip" (Required)

    The robot's IP address.

  • "script_file" (Required)

    Path to the urscript code that will be sent to the robot.

  • "script_sender_port" (Required)

    The driver will offer an interface to receive the program's URScript on this port.

  • "tf_prefix" (default: "")

    Please add description. See hardware_interface.cpp line number: 74

     robot_hw_nh.param<std::string>("tf_prefix", tf_prefix_, "");

  • "tool_baud_rate" (Required)

    Baud rate used for tool communication. Will be set as soon as the UR-Program on the robot is started. See UR documentation for valid baud rates. Note: This parameter is only evaluated, when the parameter "use_tool_communication" is set to TRUE. Then, this parameter is required.

  • "tool_parity" (Required)

    Parity used for tool communication. Will be set as soon as the UR-Program on the robot is started. Can be 0 (None), 1 (odd) and 2 (even). Note: This parameter is only evaluated, when the parameter "use_tool_communication" is set to TRUE. Then, this parameter is required.

  • "tool_rx_idle_chars" (Required)

    Number of idle chars for the RX unit used for tool communication. Will be set as soon as the UR-Program on the robot is started. Valid values: min=1.0, max=40.0 Note: This parameter is only evaluated, when the parameter "use_tool_communication" is set to TRUE. Then, this parameter is required.

  • "tool_stop_bits" (Required)

    Number of stop bits used for tool communication. Will be set as soon as the UR-Program on the robot is started. Can be 1 or 2. Note: This parameter is only evaluated, when the parameter "use_tool_communication" is set to TRUE. Then, this parameter is required.

  • "tool_tx_idle_chars" (Required)

    Number of idle chars for the TX unit used for tool communication. Will be set as soon as the UR-Program on the robot is started. Valid values: min=0.0, max=40.0 Note: This parameter is only evaluated, when the parameter "use_tool_communication" is set to TRUE. Then, this parameter is required.

  • "tool_voltage" (Required)

    Tool voltage that will be set as soon as the UR-Program on the robot is started. Note: This parameter is only evaluated, when the parameter "use_tool_communication" is set to TRUE. Then, this parameter is required.

  • "use_tool_communication" (Required)

    Should the tool's RS485 interface be forwarded to the ROS machine? This is only available on e-Series models. Setting this parameter to TRUE requires multiple other parameters to be set,as well.

Published topics

  • "robot_program_running" (std_msgs/Bool)

    Whenever the runtime state of the "External Control" program node in the UR-program changes, a message gets published here. So this is equivalent to the information whether the robot accepts commands from ROS side.

Subscribed topics

  • "script_command" (std_msgs/String)

    Send arbitrary script commands to this topic. Note: On e-Series the robot has to be in remote-control mode. Sending scripts to this will stop program execution unless wrapped in a secondary program: sec myProgram(): set_digital_out(0, True) end

robot_state_helper

This node prints the robot- and safety mode to ROS logging and offers an action to set the robot to a specific mode (e.g. for initial startup or recovery after a protective stop or EM-Stop). It should best be started inside the hardware interface's namespace

Service Clients

Subscribed topics

  • "robot_mode" (ur_dashboard_msgs/RobotMode)

    Topic on which the robot_mode is published by the driver

  • "safety_mode" (ur_dashboard_msgs/SafetyMode)

    Topic on which the safety is published by the driver

Actions

  • "set_mode" (ur_dashboard_msgs/SetMode)

    Action server to set the robot into a specific mode (e.g. RUNNING). If desired, program execution can be stopped before switching modes and/or (re-)started after the robot reached state RUNNING.

    The 'play' field is only evaluated, when the target mode is RUNNING.

tool_communication

This node is used to start the RS485 tunneling interface on the ROS machine. This requires that the RS485 daemon is running on the robot controller and tool communication is enabled on the robot.

Parameters

  • "~device_name" (Required)
