1. NXC Filewriting /20

- NXC Code looks good
- Excel plot looks good
- Excel plot /10
- NXC code /10
- Best practices: comments, whitespace, French brace comments: -2
- Syntax: floats versus ints, bytes, unsigned: -2


2. Wall-Following PID /60
- NXC code
* Best practices: comments, whitespace, French brace comments: -2
* Syntax: i is not initialized to zero: -2
- NXC code looks good
- Plots look good
- Plots missing axes labels, minor gridlines, title: -5
- YouTube videos look good
- YouTube videos don't show where the 10-cm mark is.  As such, it's unclear from the video, how much the Domabot is under- or over-shooting the 10 cm mark: -5

- One or more YouTube videos missing: -5
- One or more plots missing: -10
- Rise-time changes as kP changes: -5
* Should see rise-time decrease as kP changes
- Rise-time changes as kP changes: OK
- Steady-state error change as kP increases: OK
- Steady-state error change as kP increases: -5
* Should see error decrease as kP increases

- The videos show that the Domabot starts at the 10 cm distance.  In other words, there is no step input.  In lab, one was to displace the Domabot e.g. start 4 cm from the wall.  Doing so, one would observe the rise time as the Domabot
