Pick and place robots are industrial robots. They're useful for picking things up and putting them back down in a specific place. Some of these guys are really fast and can sort tubes of toothpaste or small chocolates coming down a conveyor belt at high speeds. Other models are used to place components on circuit boards, like this one over at Adafruit.

Now on to the videos!

In this first video we see pieces move down the conveyor belt and these two Epson 'bots pick them up and place them on a second belt. They're pretty quick but even so, the first one sometimes can't grab all the pieces and the second one is there to catch any that the first one misses.

This robot shows us how it can be used to sort small chocolates on a conveyor belt, very quickly.

A fast pick and place robot that takes tubes of toothpaste from one belt and places them on the other, changing the orientation of the tube in-flight so that they line up nicely once placed.
