Mechanical Engineering

The purpose of this project was to develop the hardware for the current Farmbot to perform its primary functions, and to create a template for a system that would be adaptable for future users and developers. The scope of the project included creating a universal tool mount, a seeding system, and a watering and nutrient mixing system. This project was brought to the students by sponsor Rory Aronson, the creator of Farmbot. The Cal Poly Farmbot team was able to go through an extensive brainstorming and iterative process for each part, where testing was able to be incorporated immediately due …

STAR Program Research Presentations

Additive Manufacturing (AM), also commonly known as 3D Printing or Rapid Prototyping, is a method of manufacturing that provides for the ability to make intricate internal features and easily customizable parts. The concept is to break a Computer Aided Design (CAD) file into a series of thin layers that are sent to the machine and laid down one layer at a time. Just like any other form of processing, material properties can alter by undergoing this process. Manipulating various parameters of the AM process can allow for different properties to be achieved. For this reason, an in depth study will …
