These were complex courtroom models used to help explain machinery mechanics. The models represent two competing systems for robotically delivering prescription drugs to a pharmacist or nurse in a hospital.
Our models show the mechanics of the device. We placed hundreds of medicine packs on twelve rotating belts to demonstrate the flexibility and usability of the design. The question was, did this belt driven design step on the other robotic delivery patent. The answer was no, our model showed clearly the significant difference in technology used in designing their device. An article on the trial results can be found here.
