@ridgerunner Thanks for the comment. In fact it's the four bots that trigger the mechanism by knocking down the balls. But sometimes the mechanism unlocks before the last ball falls.

Nice visual design but it was too hidden. Too much trial and error without seeing... By the way, three R bots were enough. Thanks!
