so this post would fit in the "RC Equipment" section as well as here...
i started working towards a UAV around 6 months ago. it's something i had considered for a while as a natural extension of my robotics hobby.
since then i've only got as far as building RC equipment and teaching myself to fly.
i chose the CYRF6936 over the many XBee type solutions as it offers far more flexibility, albeit at the price of simplicity.
one big advantage over the XBee is i am not tied to the XBee packet format so my system has very low latency.
i believe my DIY RC system is a far better starting point for a UAV for several reasons.
first, i will not have to mess around interfacing off the shelf RC equipment to a microcontroller.
everything is done on one microcontroller.
another big benefit of using modern radio transceivers instead of RC equipment is it allows 2 way communication.
at the moment i am only sending signal quality data back to the ground station but once i start adding on board sensors this feature will greatly simplify debugging.
if you wanted to there is more than enough bandwidth and low enough latency on my system to process all sensor data and calculate control data on the ground station.
not that i want lots of bandwidth between the UAV and ground station for my final solution.
my end goal is for an autonomous UAV but as an intermediate step it allows for great flexibility and easy real time debugging.
anyway, have a look and let me know what you think:
