I wanna get like 8 of these things and put em in a big loop
That's pretty cool, it looks like it's just using clockwork to decide when to spin around, instead of a sensor or something. I wonder how that works.
Looks like there's a shaft coming up the middle of the "robots" which is spinning and driving the hands, when the hands get jammed by the ball the entire thing spins. Theres a tire on the front of the robot that runs on a track to lift up the arms. The letting go part I think is just gravity taking over because the track is on an angle making the robot turn faster than the shaft is spinning.
Fans have already got you beat. The Great Ball Contraption has been a popular collaboration at unofficial lego events for nearly two decades now, and the modules keep getting more and more creative. https://www.youtube.com/watch?v=HvJg3YoehYk
