Robot Viewer

The Robot viewer gathers several tools allowing to monitor the robot on which the plugin is connected:

  • Robot view displays a 3D view of the robot,
  • Motion View allows you to control the movements of the robot,
  • Dialog view allows you to watch dialog outputs and enter dialog inputs,
  • Log view allows you to watch the logs.

To display the Robot viewer, see: Running the Robot Viewer.

Robot view

The Robot view displays a 3D view of the connected robot.

Good to know:

  • an emulated robot is displayed on a blue background, while
  • the remote view of a real robot is displayed on a green background.


The Robot view toolbar allows to modify the displayed information.

Button Description
image38 Display 3D information
collision Show collisions
image39 Do not show world representation objects
image40 Do not update robot position
image41 Do not update motors position
image42 Do not show the engagement zone
image43 Do not show the perceived people

Motion View

Motion View lets you modify the joint values of each limb.


Index Name Description
A Slider Allows you to adjust the joint value.
B Current joint value

The color indicates if the requested value has been reached.

Green indicator means the current joint value equals to the last requested value.

Blue indicator means that the joint value is not (or not yet) the requested value. It could be because

  • the command execution is still ongoing.
  • the joint cannot reach the requested value due to an obstacle such as another body part or a wall blocking its way.
C Record button

Saves the defined value, when a Timeline box is currently opened.

This button can be:

  • Grey: you cannot store joint values because you are not currently editing a Timeline box.
  • Black: the current joint value is not stored at the current selected frame.
  • Black and red: the current joint value is being stored at the current selected frame.
D Stiffen chain on/off button

Sets on/off the Stiffness of the whole selected chain of joints (Head, Arm or Leg).

This button can be:

  • Green: Stiffness off, you can move this part manually on the real robot, but commands have no effect.
  • Orange: intermediate state depending on the Stiffness value.
  • Red: Stiffness on, the robot is able to move this part when requested, but you cannot move it manually.
E Mirroring option

If selected, actions (send a command value, register a joint value, etc) are also executed on the symmetric limb.

For example left and right arms will move the same way.

Log view

Log view displays the log messages generated from robot actions to aid you debug your application. You can select the log level to display.


Dialog view

Dialog view provides a visual interface between you and your robot that lets you send dialog messages to your robot.


Running the Robot Viewer

Robot viewer is run automatically when a robot is connected to your plugin.

To connect your plugin to a robot, see:
