My Capstone project at Georgia Tech was a collaboration between my team and a local company, PodPonics. They're focused on creating dense indoor growing environments for various microgreens and produce, so we designed and built two machines to help them work quickly and efficiently.
The seeder is a roll-along device that holds and distributes PodPonics' preferred seed. As the device is pushed along, the roller inside deposits seeds on the growing medium in a concise, predetermined pattern.
The harvester is a device that's temporarily attached onto the end of a rack of growing trays. The growing medium (a soft polyester) is fed through two rollers, which pinch them and process the whole sheet right out of the tray, cutting and catching the greens as they pass.
