Dear Fred,
The Mechatronics class competition was to build autonomous miniature
forklifts that would navigate a complex course. In the course, the
forklifts had to identify, pick up, and deliver three. The path that the
forklifts had to negotiate became increasingly difficult for each pallet
they encountered. They determined the ID of the pallet from a barcode
label. They received material handling instructions (i.e. which bay to
take the pallet) and traffic information from a IR Tower that broadcast
instructions from the center of the course. They also had to negotiate a
"factory door" that they sensed to determine if it was closed. Pictures of
the competition can be seen at http://www2.et.byu.edu/~eetwww/Mfet548/
The students handled the memory limitation by eliminating as many of the
programs loaded at start up that they could and making their code as
concise as possible.
The Handyboard is very useful and the students really enjoyed working with
it. However, the memory limitation was a problem for the students that did
the best in the competition. One of the students, Richard Abbott, asked
the same question back in November but I didn't see any responses. Since
the topic of memory came up was hoping someone might be willing to share a
solution - if there is one.
The idea to have a Mechatronics competition came from seeing your work at
MIT, and the Handyboard greatly facilitated building the forklifts. For
this I want to say thank you. It made big difference in the class.
I look forward to hearing from you.
Kevin

Dear Kevin,
Please forgive this non-answering of your question, but I am curious
as to what kinds of hardware projects/software objectives were your
students working on when they ran out of 'hc11 memory, and how did
they deal with this circumstance?
Fred

| (...) How did the board read the barcode label? What equipment/algorithm was used? I've been screwing around with a train, and haven't really had any luck with reading a barcode from the track as it passes over. --- Chris Osborn FozzTexx Enterprises (...)
