Operator Control Unit

Our group also developed a custom Teleoperation Operator Control Unit, together with haptic devices that provide feedback to the operator and tackle challenges identified in various field experiments, such as attitude, traction, and traversability awareness.

This system is designed as an easily deployable and self-contained teleoperation console, integrating a GUI interface and haptic devices within a portable case. The case houses a laptop running the MEROP teleoperation software, the haptic devices responsible for attitude and traction feedback, and a joystick for robot control and teleoperation functionalities. Additionally, it includes a video camera and spare parts for the haptic devices, ensuring operational reliability in diverse field conditions.

Haptic devices

Haptic Attitude Feedback Device

The Haptic Attitude Feedback Device enhances the operator’s attitude awareness and perception of the terrain texture, when teleoperating an uncrewed ground vehicle through rough/ unstructured environments (it uses upper limb proprioception for the attitude feedback).

Functionalities
Provides absolute attitude orientation (Roll and Pitch)
Provides rate of change of attitude (angular acceleration and velocity)
Sensitive enough to provide terrain texture

Traction Glove

The Traction Glove allows the operator to feel vibration when the rover is stuck or sliding.

Functionalities
Custom made glove with vibration motors
Operators can feel different vibration patterns when the rover loses traction (depending on the state of the rover)
When the rover is stuck or sliding, the glove vibrates and warns the astronaut

Traction Cylinder Device

Functionalities
Custom made rotation device (cylinder)
Operators can feel on the palm of the hand different rotation patterns when the rover loses traction (depending on the state of the rover)
When the rover is stuck or sliding, the cylinder rotates to warn the operator

Teleoperation Graphical User Interfaces (GUI)

Raposa-NG GUI

The GUI used with Raposa-NG robot can be visualised on a computer monitor or within a Head-Mounted Display (HMD). 

Elements
Camera feeds that can be cycled through and camera main camera pan-tilt functionality, either through joystick or head rotation when wearing the HMD
Robot location in the map
Attitude Indicator (turned off when using the haptic attitude feedback device)

MEROP GUI for AMADEE-20

The GUI used within the AMADEE-20 mission can be visualised on a computer monitor.

Elements
Camera feeds that can be cycled through
Robot location in the map
Attitude Indicator (turned off when using the haptic attitude feedback device)
Information about communication latency and bandwidth when these go below a threshold, as well as a warning when there is a connection failure

MEROP GUI for AMADEE-24

The GUI used within the AMADEE-24 mission can also be visualised on a computer monitor.

Elements
Camera feeds that can be cycled through
Robot location in the map (the map also shows georeferenced user notes, points-of-interest, regions of interest, and Wi-Fi signal strength)
Icons represent information about Wi-Fi signal strength and battery state
There are two modes of operation: teleoperation mode and avatar mode (semi-autonomy)
