On Monday, Micheal Feller set up the LED IR sensors and tested some resistor values on bread board. More resistor values are needed for further testing. We want a large range for the output voltage. For example, the IR sensors that come in a package (http://www.karlssonrobotics.com/cart/infrared-proximity-sensor-short-range-sharp-gp2d120xj00f/) have a range of 0V to 3V. Later we can create some graphs for future reference.
Also on Monday, Garrett Barbour tested the DC-DC converter on the motors. The converter can only output up to 1.5A but each motor needs about 1A, therefore an additional converter will need to be purchased. Other than that, the converter works perfectly for one motor.
John Desaulos suggested a better method of attaching the motor with the bolts. As of Monday, the bolts were rubbing slightly against the wheel's lettering and the wheel was slowly unscrewing the bolt. He suggested cutting the bolt shorter with bolt cutters. On Wednesday, I went to Home Depot and the hardware department person suggested using a washer to space the bolt away from the wheel versus using a bolt cutter or a saw and cutting it. Since it was the cheaper and faster method, I bought some washers and so far they seem to be working fine. If the washers become a problem, we can revisit the idea of cutting the bolts.
The new chassis was finished Monday and everything seems to fit nicely.
Things to do:
-The wheels need to rotate smoother
-Have robot complete all four motor functions correctly
-Calculate 1 block distance forward and backward
-Play with left and right motion
