3D printed farm drone technology helps small farmers
With global population exploding, perhaps few efforts are more essential today than those aimed at developing efficient and cost-effective ways of producing food while conserving the resources necessary to do so. While agriculture has been stepped up to an industrial scale, the technology that assists in the mass production of food is often unaffordable to small farmers.
However, efforts to keep small farming feasible and potentially lucrative are being made on many levels. Electronics engineering student Krissia Quesney Nevarez is making her own contribution to the effort. Quesney Nevarez’s 3D printed farming drone, a summer project she has undertaken while participating in a 12-week summer project at Carleton University in Ottawa, the capital city of Ontario, Canada.
Quesney Nevarez, from Mexico, is one of 44 college students from across the globe who are spending their summer in Ottawa. The program in which she is participating is a competitive program for international undergraduate students from nine countries around the world, including Mexico, Brazil, India and Vietnam. The top-ranked applicants spend their college off-time on internships at Canadian universities, with teams of interns supervised by faculty members from different academic disciplines ranging from science, engineering, and mathematics to the social sciences and the humanities.
There are 14 students on Quesney Nevarez’s team and they are overseen by Jeremy Laliberté, who is an associate professor of mechanical and aerospace engineering at Carleton. The majority of the work being done this summer by Laliberté’s team of interns focuses on finding new uses for drone technology–including this electrical engineering student’s farming drone.
Quesney Nevarez had never worked with drones before she began her internship at Carleton. Furthermore, in her small university in Mexico there are no 3D printers, nor are they common outside of the academic setting in that country. Making the most of her time in Ottawa and in the interest of completing a project that had relevance both to her electronics engineering degree and her life in Mexico overall, Quesney Nevarez designed the farming drone,cr2 which is produced affordably using off-the-shelf electronics and 3D printing.
The drone is controlled remotely using open source software, flies over a predetermined area–all or a portion of a farmer’s field–and takes photographs. The photos provide a near-infrared reading that provides information concerning how efficiently plants are absorbing sunlight to facilitate photosynthesis. Farmers can use the information to adjust their distribution of water and fertilizer to their crops.
