We're driving!

So, we're driving. The chassis is all done, and all we need to finish is the tower! Sounds easy... wrong. The drive code is mostly functional, however, the PID loop delay is making our turning while driving forward/backward a little difficult. The delay causes the wheels to respond slower, so this means that when we're turning (which is usually for a short amount of time) the wheels that are going more slowly don't even start turning before we're done with the turn. Once we brought the robot back from IDEO and had more space to test we could get the slower wheels to turn a little because there was more space to practice in.

Speaking if IDEO, Jimmy had been working away on the tower. I picked up some more materials from alan steel this afternoon, so we have almost everything we need for the tower construction. I will be picking up some more stuff tomorrow. Jimmy made a nifty thing around which to construct the tower, which will theoretically prevent it from warping when he welds it.

Build worked on constructing the center brush, but without a drill press, it was hard to center the holes, so they are going to try again tomorrow in the wood shop. I am going to buy one more broom for them to attach as well.

We have eight more days until ship (feb 17th) and we will be working furiously until then!
