1/16/19 (Wednesday) - The hardware team created CAD and laser cut acrylic for the final frame that will hold the sixteen paint cans. They also tested different nozzle prototypes made from paper to try to reduce the paint spray radius. The software team integrated a second ultrasonic sensor into the arduino setup and completed the code to get from the sensor readings to horizontal and vertical displacement along the tartan pattern. Also, we debugged the high-level code that determines which cans paint from which positions in order to form a relatively even pattern, while allowing for some inherent error / lack of alignment.
