Our Approach
Teleoperation Interface
Minimize the exposure of astronauts to the harsh conditions outside the habitat.
Improve the perception of the situation of the rover during scientific missions.
Teleoperation Devices
Attitude Device
The astronaut feels the inclination of the rover
Traction Device
The astronaut feels vibration when the rover is stuck or sliding.
Onboard Autonomy
Avatar-based Navigation
The astronaut controls a virtual element (avatar) that the rover autonomously follows
Image Augmentation
Predictive Displays
The astronaut sees the predicted path of the rover during latency periods.
Autonomy & Augmentation
Description:
• Aid operator during latency periods.
• Avatar-Aided Interface (AAI), a Semi-Autonomous approach based on a virtual element.
• Predictive Interface (PI), an approach with direct control and predictive elements to predictive rover status.

Attitude Device
Description:
• This attitude haptic device provides the analog astronaut with the information of the rover’s orientation in space (attitude).
• Attitude of the rover will change due to terrain inclination.
• When the pitch and roll of the mars rover changes the analog can feel, on the hand, this information.

Traction Device
Description:
• The astronaut 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.
