Can LEGO Juggle?

In this video, I design and test different ideas for a LEGO juggling machine to juggle ping-pong balls. I started out by creating mechanisms that used springs to launch the balls: these worked really well with just one or two balls, showing great accuracy and reliability. However, they simply couldn’t keep up with the higher speeds required to juggle three or more balls. I then moved on to a design that used spinning wheels to throw the balls. After several iterations to improve the speed and accuracy of this juggling mechanism, I settled on a finalised design that really impressed me, and I had a lot of fun watching it juggle. Enjoy the video!

great vid mate

Thank you!

I think this would benefit from some lateral ties locking the bases together. They kick a bit on each launch and it eventually messes up the alignment.

That's a nice idea, and that was actually how I was initially planning to do it. The problem is, for whatever reason the batteries I was using in each battery box didn't give quite the same power (even though they all came from the same pack), so one of the launchers would always shoot the balls higher than the other. This meant I couldn't put the launchers in symmetrical positions because one of them would always miss, so I found it easier to just manually tweak their positions so that both of them could catch the balls. The other problem was that the batteries lost power over time the more I ran it, so the balls were being launched shorter distances and I had slowly bring the launchers closer together over time and I could't leave them at a fixed distance apart.

that's pretty damn cool

Thanks!

That last design was VERY elegant! The way it uses the incoming ball to trigger launching another 👌

awesome :)
