+# 8 Hill Climb
 
 The purpose of this exercise is to program the Pololu robot to execute a specified task, namely to climb a ramp, detect when it reaches the top, turn around, and drive back down the ramp, all without falling off the edge of the ramp.

Hence, in this lab, you will only use the line sensors.

 2. Instead of setting the power level of the motors, a better strategy might be to set a desired robot speed.  How might you use the encoders to measure the speed?  How might you use the speed measurement to control the speed?  **Hint:** Section 2.4, Feedback Control, of [Lee and Seshia](https://leeseshia.org) might be useful.
