VASO considers writing code to be an integral part of building a device, so the Constructed Devices Policy applies to the code as well as the physical device. To ensure this policy is being followed, teams will be required to transfer a copy of their source code file (after they have modified it during the setup period) onto a USB flash drive provided by the Event Supervisor. The team is responsible for ensuring they will have a way to connect the provided USB flash drive to their laptop or calculator.
