What exactly is the qestion? Is it if 5 chips can be balanced? Or is it if any human can actually do it?
As I said before, it's possible, but no person can do it. I expect with perfectly machined and balanced chips, a perfectly level table, and an extremely accurate and well programmed robotic arm - it could be done.
I suppose if it's possible in the above situation, if you had an infinite number of people trying to do it for infinity then.... it'll happen eventualy. Then with the slightest vibration, they would fall over.
Enough babbling

yeah but robot arms built by humans arnt that great, you'd need a robot arm built by robots for it to work
