On a totally different note, the robotics team is transitioning to C++ this year from straight C. The communications system between the robot and driver control station is 802.11n. Each robot forms an on-board network between its controller (cRIO from National Instruments), camera (etherlink connected), and uses a game controller to talk back to the hub (Linksys/Cisco 802.11n wireless router). The router sits back at the "driver station" so it has access to line power to drive the router. Two USB joysticks (logitec) provide operator control.
