This is pretty cool. LEGO robots are used in the lab at Cambridge University to grow bones. There are a few things I really like about this. First, it uses common off-the-shelf components to get something done. Second, the people doing the work (growing bones) did not get hung up trying to figure something out – they just went and did it. Lastly, it gives a prime example for kids that even playing with LEGOs is a worthwhile pursuit. Now I just need to get a LEGO robot to wash my pick up.
