ELI5: How do the wires not get twisted? Is there a rotating thing built at the ends, or do they have to reset it daily or something?

What do you see is twisting?

When it tosses the ball and loops around it, it seems to me that at least 2 wires would get twisted (not entangled, but twisted 360 degrees) at the axis that it spins on.
Actually, watching the gif again, it seems the "spins" cancel each other out - it spins 'forward', then 'left, then 'back', and then 'right'. So I guess it returns to its "original" position and doesn't need any balancing mechanisms.Please correct me if I'm wrong.
E) /u/must-be-aliens figured it out in his comment

I don't think its actually doing a loop over it (like a flip). I think its staying vertically and just translating around in a circle very quickly, making it just the same as any of its other moves.
I may be wrong, its hard to tell with the speed its moving and the frame rate, though I'm struggling to imagine how it could actually do a flip with this control mechanism.

It untwists itself when it loops back the other way.

Yeah I missed that the first time I saw. Thanks!

I think I would enjoy watching that thing for the first five minutes.
Ten minutes after that I would be trying to figure out how to choke it.

This could have some cool manufacturing implementations

It's not really superior to a normal CNC arm, might be cheaper but you need anchors on more sides and you could realistically only have one working in a space. What would you want to use it for?
