This is my individual graduation project for bachelor of science in mechanical engineering. I fully designed the system based on engineering knowledge and calculatio as well as accounting for prices of real components. The supervisor requested a concept but I was determined to design and fabricate a functional product but sadly I didn't recieve funding to bring the project to life so I had to resort to a simulation using C++ and ARDUINO codes to run on WEBOTS. Finally, air flow simulatio were conducted on the grass cutter's bag to guarantee its optimal functionality (again stressing the amount of engineering knowledge that went into such project).
