Sensabot

In this challenge we were asked to build a robot that could drive and then stop at three red lines. At each line it will lower then raise an arm. After the robot gets to each line it will return to the start. Here is an example.

The robot has a color sensor that tracks change in color and then it activates a motor which lowers the arm and will then raise the arm. We took a screenshot of the program, and here it is.

We faced a few difficulties during the build like we had to figure out how to use the color sensor because we have never used one before. Another problem we faced was getting the bot back to the start, we tried using the color sensor but it would keep going past the box. We then figured out that there is a block that track the number of times the motor rotated and would spin the motors in the opposite direction. Our goals for the next project is to make it work a little more consistently because sometimes the color sensor wouldn't pick up the change in color and would just drive past the end.
