Chapter 6 was pretty much about building strategies. How to build with the extra support so that the robot will be more stable in when the robot is performing tasks? Building a robot is like building a car, in a car you need a support structure or the car will just fall a part same with a robot. When first built my robot the first time at the beginning of the term I had this same problem I though it was a good idea to put some extension axles were the wheels went and then they both started to bend when I had to put the NXT on the robot because of how much the NXT weighed, also during the last challenges I had to change the location of the NXT and how a placed it. Another thing to think of when building the robot is to separate the left and right drive assemblies you can not just use one axel for the wheels because when you only want one motor to run both wheels are still going to move but one want them to run on there own. Stud less beams are great for support to. The NXT needed to be to be centered so that the robot won't lift up on either side.
