Scientists and students at the Cambridge University department of engineering are working on a way to create artificial bone, which they hope one day will be used in implants.
The artificial bone is created by dipping a sample into a variety of different substances, the artificial bone is then built up over a period of time and the process is repetitive, so the researchers decided to use Lego robots to create the artificial bone for them.
As you can see from the video the robots are used to automate the process, and each one of the robots cost around $280 to build, which we suspect is quite a bit cheaper than buying in robots to complete the task.
