Today, I learned about using an encoder to make the robot go a certain
distance. The encoder works by counting how many of its gears go by. I
had to calculate the circumference of the wheels and use a simple
formula in order to know how many ticks the encoder would have to go for
12 feet and to make a left and right 90 degree turn. Last we had to
program the robot to go through the maze we had it go through on day 9
but with using the encoders. Doing this was much easier and more
accurate than the previous method of running the motor for a certain
period to go a specified distance. Unfortunately it took us the whole
class period to program and run the robot with the encoder so only one
team was able to negotiate the maze.
