To get a better idea, see this source for a roomba setup (it's really pretty short and simple). http://code.google.com/p/ece-capstone-design/source/browse/trunk/TriDemo/RelPosition/DualProx/main.cpp The block of interested is the one with the comment "Turn while backing up for 3 seconds" This is where the network traffic drops way down (I'll try to attach a screenshot of a network monitor), and there is quite a lag between hitting the bumper and actually backing up. This point in the program is where most likely to crash. It could also be my use of "DualProxy"'s, which are just structs that hold a proxy to a real robot and a proxy to a Stage robot. I'm a engineering student, not a master programmer. If I run the client program on the robot itself (ie - no wifi, no stage), the program does not crash.
