Re: Looking for an IFI mobile RF modem

So far i have a joystick that sorta controls the car, and the wireless camera/headgear combo works great. Still need to tie the head tracker into the operator module and make the mobile module "mobile". Just FYI, without knowing much about the topic I chose the IFI Robotics controller because it is supposed to have a saw tooth pulse rather than a stepped pulse and that (so I've read) is what the RC car's speed controller prefers. Were it up to me I would rather have a OOPIC controller because I already know C++ and would not have to mess with PBasic. Although I see that the newer IFI models support C++. Advice welcome!

After using the oopicII for some of the control circuits on my team's darpa grand challenge car, i will never use them again. The IFI system is great for it's simplicity of use but for heavy video processing you might want to look for a stand along micro controller card that utilized a bus that supports higher speeds. It does sound like a cool project and be sure to post some photos here to the boards when you get done. Also if you need tech advise or anything these boards are great for that as well. good luck
