This past week we placed the final orders for all our parts, began the initial assembly of the AutoCart system, started interfacing the Raspberry Pi with the line following sensors, and are working on the user inteface that customers will interface with. These are all being done in parallel in order to maximize efficiency. We are striving to have the line following sensor interface and user interface done by the end of spring break in order to start system integration of these two parts so that we will have functioning line following Roomba by the interim demo.
