Cambridge University researchers are using LEGO robots to help create artificial bones for medical and construction uses. To create the bone-like substance, the researchers must dip a sample into a beeker containing calcium and protein, rinse with water and then dip it into another beeker with phosphate and protein. The process is repeated many times. To automate the processes, instead of buying very expensive automation kits, the researchers assembled LEGO pieces and programmed them to precisely follow the regimine. Thanks to the dutiful robots, a fully made sample can be accomplished in one day.
