Modern society owes so much to medical research, though what happens behind the scenes in a laboratory is usually far less than glamorous. A group of scientists at the University of Cambridge are working to develop synthetic bone tissue, but the process to create the samples used in the study is incredibly tedious.
To make the bones, a substructure must be dipped in a mixture of calcium and protein, rinsed, then dipped in a mixture of phosphate and protein…hundreds and hundreds of times. Equipment that can automate the process is available but very cost prohibitive, so the scientists did what they do best and built a set of robots to do the work for them.
Their new bone manufacturing setup was constructed using Lego Mindstorm kits, which were a perfect solution to their problem in several ways. The kits are relatively cheap, easy to construct, easy to program, and able to perform the same function precisely for days on end.
Now instead of burning time manually creating synthetic bone samples, the group can focus on the more important facets of their research.
