Robot now runs straight (mostly)

Meeting #20 - Caitlin and Mr. Mack built a new robot that appears to track straight. We had to use a tachometer to test all of our motors to find the two that were the most closely matched. Then, we experimented with gear designs. We found that allowing the motor to run at the highest RPM produced the most consistent results and ultimately, the straightend travel. We geared down the rotation sensor so, hopefully, we will have better control over how far our robot travels. The other girls split into software teams of 2 girls each and they made great progress on several of the challenges. Of course, it remains to be seen how well our new robot design will work. We will try this on Monday. Mr. Mack will prepare a lesson on Arm design and how to use a worm gear for strength.
