Accomplishments:
- built mixed relay transistor motor control circuit
- tested circuit with both motors (big & small)
- circuit works
- testd circuit with motors but powered with batteries instead
- big motor doesn't turn much
	- too much voltage drop over circuit when large motor is used
	- why?? Hmm...
	- draws too much current
- small motor will be a lot easier to implement and there will be fewer
complications


Questions:
- Is the level where the touch sensors are going to be mounted on made out
of 3/8" Lexan?
- I thought we were mounting the touch sensors on the bumper (lowest
level).
- robot getting increasingly heavy - wgt prob?
- If robot is too heavy, I wonder if our motors will drive it...
