Wow, I never thought I'd see my name in a subject line!
I built the Killough platform for the March SMART meeting mini-challenge.
(SMART is the Seattle Mindstorms and Robotic Techies group.)
The basic idea was to build a robot to wander around a table, without
falling off, and stop beside a heavy object.
(See http://news.lugnet.com/org/us/smart/?n=15 and a follow-on note
http://news.lugnet.com/org/us/smart/?n=23 for details about the meeting and
mini-challenge)
I've wanted to build a Killough platform for a long time, and here was
finally a reason to do so. The greatest challenge was keeping the robot on
the table. I built the 'shell' to act as a one time, 360 degree touch
sensor - it rests atop a light sensor, and when the robot runs into the
heavy object, it is pushed off, thus changing significantly the light sensor
reading, and the robot will stop.
Sorry I don't have a movie of it working, (someone else just posted a
reference to their page where they have a movie, my robot is very similar)
but I will be posting further pictures and a more detailed description in
the SMART group in the next few days.
