This year in 1690, after reading the full game manual, we made a list of all the requirements and specification for the robot.
Then, we've came up with few possible options for every system, and we build a working prototype for most of them.
After testing every concept, we've voted for every different systems (drive train, intake and shooting) and we build a full prototype robot, with all the different systems, as you can see in this video:

The prototype robot let us test the program + gave the driver some practice weeks before the real competition robot was finished.
