Generate Concepts
Develop a solution
We started this prototype by both of us making a sketch of what we thought the prototype would look like. After that we figured which one would be the best and then went straight to building. When we finished building the simple design w went to the computer and started programming the robot together in order to make the wind and unwind the string.
Evaluate Solution
Some problems we endured while making this project is after we had made the program and uploaded it to the robot the motor were not working right and the string was under so much tension that is snapped 3 times. We had to try different speeds and make sure the motors were spinning the right direction or make sure the string did not get caught on anything.

Conclusion
One programming feature we learned to apply here was the while statement so the program we wrote would loop to let us preform it multiple times. I think the most surprising thing was how short the program was, i was expecting it to be longer. The most difficult part was trying to get the two motors to turn in different directions at the right time so that the string wouldn't break. Two things we could have added would be a sensor that could read a certain line that would be a certain measurement. We also could have added shaft encoder that could measure a certain revolution and stop at that measurement.
