A big reason to build a 2nd robot this year is the autonomous part of the game this year. With a 2nd robot, your programmer get to have 2 weeks to mess with the program, and perfect it before competition. That way, they make up the time waiting for the rest of you guys to finish the robot.
And for that, you don't even need to clone the complete robot. Just similate the 130 lbs, and copy the drive train and sensors. And remember, the only spare parts you can use on the real robot have to be manufactured during the 6 weeks, or directly from the kit of off the shelf items.
Before you are thinking of cloning a robot, finish the first robot first
