As derivative of earlier projects Duckweed and Drone, project Lemna arose as mean to create agtech solutions. Lemna got to life during the Master in Design for Emergent Futures program as a binding derivative between sustainable design, agri-tech and future-food alternatives. With a distributed and applied-design approach, we developed on a series of multi-faceted themes where it wanders into radical new roads exploring it’s future in a broad spectrum of know-hows. It’s recognised by open-sourced knowledge systems and touches upon a defined series of urgent + contemporary scenarios, including the food of tomorrow, rural futures and shared learning. Since it’s recent kick-off, Lemna has already resulted in series of approaches comprising an Agri-drone, a Water-lentil Incubator and a Hybrid multi-sensorial monitoring system + device. By applying to IAAC’s Advanced Architecture Contest on Bio-cities we intend to bring Lemna’s approach and solutions to the self-reliant ecosystem it proofs to resonate with. So as to continue to explore and construct meanings in various transitions towards a biologically revitalised future.

Lemna consists of a series of physical and digital products.

Oracle monitor

As first physical and digital hybrid outcome of lemna, the scan- and monitorunit Oracle was created to gather and communicate environmental data. The object has five on-board sensors measuring aerial humidity, aerial temperature, media moisture, media temperature and light.

Oracle mini

As in-depth exploration of electronic design we created an mini version of the Oracle monitor with the same functionalities in 25% of the volume. We design and milled a customized PCB with SMD (=Surface Mount Device) LED and phototransistor chips.

Growing stand

After researching reference material on broad cultivation of water lentils and food-safety within Lemna Minor we created an vertical growing station in which three trays of 8 liter growing media are positioned.

In recent years agricultural robotics and drone monitoring have increasingly become affordable and popular. Since its still a young technology all its limits and possibilities are far from reached. The main concept of having a flying tool at your disposal is interesting from a lot of viewpoints and for a lot of potential use cases. For these reasons plus the encounter I had with Aurora del Camp, I pushed second term's quadcopter to a more applied approach. Full process documentation can be found at second term's page and Discord channel.
