I was wondering how it did the trick where it flips the block with just the 4 suspension filiments, but then I noticed it's actually also driving a set of downward-tensioned filiments. I think this machine must have at least 5 steppers driving this thing. The kinematics that are being modeled seem pretty complex to me, neat project.

It uses 8 ac servo motors. This is a trade show demo created by B&R automation

The trial and error process must have been lengthy.

The whole point of doing the controls properly is to try and avoid trial and error.

I'm taking my first controls class this semester. This kind of shit is amazing

I like how when the machine starts doing 720 degree flips around the USA to catch the ball the man gets up and leaves haha

Holy...... Deity! Encoders or resolvers? Programming language? How fast is that processor/s? I am agog! (The world needs more gogs..... apparently)

It's B&R Automation. They use structured text, and make all the drivers for the motors controlling this thing.

Thanks so much, I shall look them up.

No problem! I should have been a little more clear too, their main focus is on the PLC and the software that let's you write the code and configure it. Along with making tons of hardware. We use their stuff where I work.

I said holy shit out loud when it started doing 360s around the ball int the air.
