| The computer runs Ubuntu Linux, so a crontab entry controls the
| scheduling. The script calls eject /mnt/cdrom to open the CD Rom,
| delays, and eject ?t /mnt/cdrom to close it again. It actually does
| this twice, as I found it made the portions more consistent.

Do-It-Yourself Robots with Linux
,----[ Quote ]
| My goal is to share what can be done with inexpensive, easy-to-obtain
| parts and our favorite operating system. Linux is loved by tinkerers
| and hobbyists, and an exciting and challenging extension to this line
| of tinkering is to add motors and sensors and autonomy. Like peanut
| butter and jelly, Linux and robotics are a perfect combination!
