Re: CMUCam for drivers

Any display of "robo-camera-view" to the drivers would have to be considered a functional, not decorative, capability and would be subject to the restrictions against wireless communications. Within the rules, it is technically possible to get an image from the CMUcamII back to the OI and potentially displayed on a dashboard computer. However, it is not practical. As previously noted, you cannot add another wireless modem/transmitter to the robot, so any signal must be passed through the RC and IFI radio. So the image from the camera must be encoded, passed through the TTL port on the RC, dumped into one of the data buffers and packetized, sent via the IFI radio to the OI radio, stripped out of the packets, passed through the dashboard port, and re-assembled on the dashboard computer. The biggest bottleneck in the process is the link speed between the RC and OI radios, which were never designed for streaming video (remember, they are only 9600baud radio modems). So, at the end of the process, you are able to get one image about every 60 seconds. Hardly worth it.
