- About the blimps, the group in Austin is called The Robot Group and
- you may have seen it in a recent Invention program in the Dicovery Channel.
- There are at least three blimps currently but (as far as I know) none of
- them was used to simulate "fish behavior". All of them use propellers.
-
- One of them uses a rotating sonar range finder which gathers data for a
- neural network and learns to navigate without bumping into walls. This one
- can lift several pounds and has a 68HC11 and 332BCC onboard.
-
- There is another one which has two wings on the bottom that provide the
- forward propulsion. It is radio controlled. It has two legs on the
- bottom that makes it run to take off.
-
- There was a "fish" blimp which has a "fish" tail that provides the forward
- propulsion. This one has a few PWM-controlled fans for altitude control.
-
- If there is enough interest, we have a video tape of the blimps (and other
- robot projects we have) that we can make available for a nominal postage
- and duplication donation :-). Please contact me for more information.
-
- We have put so far three Robofest shows (one more coming next summer/fall)
- and in addition of the blimps, we have a wide variety of robots, including:
- the Robot Band, ProtoAndroid, Varmint (a four legged walking robot), the
- Pittbull dog (a pneumatic robot dog), DweebVision (an inexpensive telepresence
- demonstrator). There are some other projects related to virtual reality.
-
- The Robot Group is a non-profit organization and meets once a week around
- some beers and is mostly formed by artists, scientists, students and
- engineers from local industry.
-
- We have many ongoing projects which include the 68HC11 and 68332
- microprocessors, in miniboards, 332BCCs, our own custom HC11 board and
- EVBS, and we are interested in corresponding with people involved with
- any software tools for these processors.
-
- For one of the projects we have, I was wondering if there are any you out
- there who have written any routines for the SPI for either the 68HC11 or
- the 68332 (e.g. for the miniboard).
-
- I am trying to write primitives for message passing communication
- in a string of daisy-chained miniboards and 332BCCs. The BCCs are
- going to be in master mode in a "token-passing ring." (The
- token-passing will be done in software, not hardware, the network will
- be a parallel SPI bus).
-
- Well, since I am doing it in C and cross compiling with GCC, if the
- work is done in C, that would be a heck of a lot easier to port, but
- assembly would be accepted. The code will be available to the
- net when done.
-
- Cheers,
-
