This is a scavenger hunt in the dark. Difference is we only have to accurately map the objects we do not need to pick up and bring back. Like the NASA Sample Return Challenge. Below is a video outlining the tunnel portion of the challenge.
August 19-24 2019. The real challenge is being run so look forward to seeing how the other teams worked through the problems and did in a real run. There a only 9 teams and I believe all of them are funded by DARPA. One team will be bring home some winning. Just interested in seeing how many artifacts the winning team accurately mapped.
