Apparently making artificial bone is an extremely tedious process, but LEGO can help. Cambridge PhD candidate Daniel Strange, working in the laboratories of Michelle Oyen, has been working on ways to make bone, both for medical applications, but also for potential other materials use. The process involves repeated dipping of an object into various solutions and then rinsing. Daniel wanted to automate this process, but buying a commercial robotics system would be extremely expensive. So he built his own, using Technic pieces and a NXT system to control the whole thing.
