  14. (10/18) Two days ago we sent out an email to everyone working on the vision challenge problem regarding new debugging output we're providing. Today we sent an email to everyone on the LittleDog project about a fix of the display flickering problem. If you are working on one of these projects and haven't received the corresponding e-mail, please let us know.
  15. (10/13) Problem set 2 and programming assignment 2 have been posted.

  17. (10/5) Special section Tuesday 10/6 from 5:30pm-6:30pm in Hewlett, room 200. We will talk about the challenge problems (Little Dog and vision) in more detail. As with all sections, attendance is optional. The PowerPoint slides will be posted here tomorrow, and the video should be posted on the SCPD website by the end of the day on Wednesday. The project handouts can be found here
  18. (10/2) Programming assignment 1 has a small bug. Please download the latest code or see the FAQ for a simple fix.
