Is there any way to ask iRobot for more time to work on the robot? I got the robot on July 26th. I ordered extra parts from iRobot; a light sensor and the breakout board, and both items are on backorder for several weeks. The contest ends August 31st. The timelines set by iRobot are not realistic, especially if they can't supply supporting parts for the robot. What can be done to mitigate the short timelines?
