3D Modeling and Design Project

At the end of my first year of university, I was assigned into a group and was tasked to create a squash ball launcher from scratch using the skills we were taught throughout our second semester. We were tasked with having it fired remotely, and with a manufacturing limitation of a £50 budget. I chose the role of 3D modelling and prototyping. After many design itterations, I landed on the propultion mechanism of 2 flywheels. For the full design, I created a housing for two 15V motors with a 3% compression of the size of the squash ball, and a trapezium shaped attachment point for adding the base and ball slide. Then I created the base in tandem with a "foot" to change angle of fire for range. Lastly, I designed a tube slide for the ball to roll down with speed into the flywheels, else it would stall the motors. I modelled a cutout at the top of the tube to fit a servo with an arm to hold the ball at the closed position, where pushing a connected button would operate the servo and move the arm, dropping the ball down the tube. All these electrical components were connected to an Arduino and also coded by me.
