Five working NXTs
We found out that it was in fact possible to control five NXTs via Bluetooth from one computer.
It is straight forward in the .NET framework. All you need to do is to open a serialport (COM) to each NXT.
Once a serialport is opened, it is possible to send "Direct Commands" to the NXT. That is, you can remote control everything on the NXT. LEGO has published the protocol used for doing this. What you do is to send a number of bytes to the NXT, and it can reply (if wanted).
This is the approach iCommand uses.
Using this approach, some of the autonomous idea behing our project is undermined, while the NXTs will not run any code, but just be "dumb" remote controlled robots. However, given our situation and having time as a factor as well, this looks like it could be our choice of approach.
