First, to bad we seem to have started off on the wrong foot.
Forgotten and forgiven.
Allow to clarify my objective.
The design and construction of a remote control device based upon Arduino with the explicit aim to use
it to remotely control ROV’s (air/land/water based). The ability to send commands to the ROV for steering
and de/activations of functions. Have the ability to receive telemetry from the ROV and display them on a
screen on the remote control( such as sensor readouts, battery status, etc).
The only weak spot I have is the selection of a suitable RF data transmission technology. One could indeed
use Wifi, but it has probably a to a limited range and might not meet the latency accuracy needed ?
Range : <1000m outdoor
Bandwidth: >= 2Kbps
Direction: bi-directional, preferred for telemetry feedback.
Freq.: Preferably not 2.4GHz … (potentially subject to interference ?)
Currently I’m looking a transceivers from Hope RF, namely the RFM12 series http://www.hoperf.com/rf_fsk/cob/RFM12.htm
and it is supported by Arduino http://www.open.com.au/mikem/arduino/RF22/
I know there are still other considerations that need to be cleared, such as which Arduino to use.
Chances are the UNO could lack some processing power to control the transceivers.
If you have any experience that could help me avoid common pitfalls I am very much interested and it will be very
As I have stated before, I do not yet have a detailed end-result in mind. I have an idea and am trying to figure out
what the feasibility boundaries are. Data transmission is just one of them. This is a true father/son project, and in
case you have kids you’ll understand what I mean Father build, son creates the feature requests and plays
Hope this clears the air,
