My next robotics project is a "1 cubic inch robot" and I am planning to add a 2 way wireless communication between my robot and a computer. Since for that size Power is a big bottleneck the best I could come up is a IR transceiver. So how can I achieve this ?
If I use a 38khz receiver then I might end up receiving the same transmit signal ? what Is the best option I can use in my application ??
