In the long run, the communications transmitted are more important than
the communications. These are going to be model sized(using modified
tonka trucks). And will at most, operate over a range of about 100
yards(at most, more likely is 10 yards). Also, they do not require
continuous transmission, but rather can transmit information when
within range of each other. The information is mostly used to
synchronize, not control. The control will be done onboard the
individual vehicles. For this reason, we have viewed bluetooth as being
sufficient. The problem we are having now is finding an easy(and
preferably semi-cheap) way of integrating bluetooth into these devices.
The chips I've seen so far have had development environments costing
1000+. Wishing to concentrate on developing the autonomy of these
devices, we'd like to minimize the amount of time implementing the
mechanics of the communication, and would rather concentrate on the
data to be communicated, and how to handle when to transmit.
