dashboard/raw_request (ur_dashboard_msgs/RawRequest)

General purpose service to send arbitrary messages to the dashboard server

dashboard/restart_safety (std_srvs/Trigger)

Used when robot gets a safety fault or violation to restart the safety. After safety has been rebooted the robot will be in Power Off. NOTE: You should always ensure it is okay to restart the system. It is highly recommended to check the error log before using this command (either via PolyScope or e.g. ssh connection).

Shutdown the robot controller

dashboard/stop (std_srvs/Trigger)

Stop program execution on the robot

Parameters

dashboard/receive_timeout (Required)

Timeout after which a call to the dashboard server will be considered failure if no answer has been received.

hardware_interface/joints (Required)

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.

non_blocking_read (default: "false")

Enables non_blocking_read mode. Should only be used with combined_robot_hw. Disables error generated when read returns without any data, sets the read timeout to zero, and synchronises read/write operations. Enabling this when not used with combined_robot_hw can suppress important errors and affect real-time performance.

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)

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.

servoj_gain (Required)

Specify gain for servoing to position in joint space. A higher gain can sharpen the trajectory.

servoj_lookahead_time (Required)

Specify lookahead time for servoing to position in joint space. A longer lookahead time can smooth the trajectory.

tf_prefix (default: "")

When the robot's URDF is being loaded with a prefix, we need to know it here, as well, in order to publish correct frame names for frames reported by the robot directly.

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
