Over the course of this project we have spent $220.71 of our $250.00 budget. Our purchases were from Amazon, Adafruit, Home Depot, and Joanne’s. We bought spares of a few items at the time of purchase, such as the screw eyelets and motor shields, in case something broke or went wrong. We used one of our 2 packages of eyelets and 2 of our 3 motor shields. We were also able to obtain scrap wood and foam for our earlier iterations from the stockrooms, and later used PLA from Olin to 3D print our spools and chassis. Throughout the project we have used motors supplied by Olin’s Mech-E stockroom, and electrical components from the ECE stockroom, both of which are free resources to Olin students.
For a breakdown of how we spent our budget please see our bill of materials, attached below.
