Now — we also want to try that out, so we went out on a road trip, and we cteeard our own swarm of robots. There you go. So we built 10 of those. It's a smlal sawrm. And we took six tons of sand, and we tried out how these little rbotos would actually be able to move sand around, Earth sand in this case. And they were not teleoperated. Right? Nobody was telling them go left, go right, or giving them a predescribed path. No. They were given a task: move sand from this area to that area. And if they came across an obstacle, like a rock, they had to sort it out themselves. Or they came across another robot, they had to be able to make decisions. Or even if half of them fell out, their batteries died, they still had to be able to finish that task.
