The key to providing live interactive museum tours to remote students lies in a clever combination of the latest technologies.

Robot

Our telepresence robot is built on a commercial robot base which carries a head-height omni-directional camera and a display screen. It also has a forward-looking camera and a number of onboard computers and wifi antennas.

The educator wears a wireless lapel microphone, to ensure that they can be heard clearly by the remote students. They can see who is online, and which students have questions via the display on the front of the robot.

The robot moves at walking speed within any wheelchair accessible space. It intelligently navigates to different locations in the museum under the supervision of the educator or guide. It can sense walls, exhibits, and people around it using a laser scanner. The robot’s navigation is based on a self-generated map of the gallery space and a sophisticated dynamic obstacle avoidance system.

360 degree camera and panoramic viewer

Using a 360 degree camera mounted on top of the robot, we construct and stream a high resolution omni-directional image. Each remote student can then independently ‘look around’ the gallery using a panoramic viewer within their browser.

Remote students each control their own view within the panorama
