Researchers at the Department of Engineering at Cambridge University have enlisted the help of some custom made LEGO robots to grow artificial bone samples. In order to build up the bone grafts, a scaffold needs to be repeatedly dipped in a number of different solutions to grow the compound, a highly repetitive task that lent itself to a little bit of home-brewed automation. The team built cranes from a Lego Mindstorms robotics kit, which contains micro-controllers, actuators, and sensors that can be programmed to perform sequential tasks. The synthetic bone scaffold was tied to a string at the end of the crane, and the whole setup was able to perform the sequential layering needed to grow the composite bone.
