Putting Oculus Rift on a Robot

Share it

Many of the early applications for the much anticipated Oculus Rift VR rig have been in gaming. It’s interesting to see some more useful applications besides gaming, before it’s commercial release sometime this year.

So he built the Intuitive Rift Explorer a.k.a IRE. The IRE is a moving reality system consisting of a gimbaled stereo-vision camera rig transmitting video to the Rift, and matching head movements received from the Oculus Rift.

The vision platform is mounted on a Remote-controlled robot which is completely wireless.

He had to tackle the problem of latency – reducing the time from moving the head to getting a matching image on the headset – Oculus Rift team specified it should be less than 20ms. The other important requirement is a high frame rate, in this case 60 frames per second.

JoLau] provides a detailed description of the various sub-systems that make up IRE – the Stereo camera, audio and video transmission, media processing, servo driven gimbal for the stereo camera, and control system code.

JoLau]’s reasoning on some of the interesting hardware choices for several components used in the project makes for interesting reading.
