This project currently is in draft status. I will update the article on my homepage, as it progresses.

Normal R/C transmitters are not the best way to control a UxV. For instance, they usually require additional components like ArduStation for the ArduPilot project, which means, the operator has to start juggling already with 2 components. Depending on mission and payload, there easily might be 1 or 2 more systems added. Based on this idea, I started thinking about a UxV controller which at least inconporates the R/C transmitter and the mission control component.

The R/C TX component is based on modules. I am planning to use the FrSky DHT module which is especially for integration in user projects. Another possible option would be to cut a matching rectangular hole into the UxV-CS' enclosure e.g. for JR compatible modules. The main board could be taken from a cheap chinese radio, e.g. the Turnigy 9x, but I am planning for the ERSKY9x board. The ERSKY9x board is a third party board which was developed as an improved replacement board for the 9x radios. It features a much more powerful CPU and runs Open9x firmware.

Instead of the usual R/C-joysticks, the UxV-CS will have 3-axis joysticks which pushbuttons. Additionally, a linear slide potentiometer and several switches are planned on the TX side.

The mission control component will be based on an Arduino Mega 2560 with a 40x4 character LC-display. The Arduino will feature  "softbuttons" with changing functions as well as a 4x4 matrix keyboard for data entry. Those will be complemented by mission-related switches and an external joystick module for camera operations. Also, a mini thermal printer will be integrated e.g. for adhoc printing of GPS coordinates in SAR missions. For communications, the 3DR 433MHz modules are planned.

maybe the ardupilot GCS should be restyled to an app simular to that from parrot ardrone.
Then you only have one device for flying the uav and control its missions and do everything else.


To avoid lag and range issues on the primary flight controls, they should also develop some sort of USB RC trasmitter (be it analog FM, 2.4ghz or 5.8ghz). Plug it in to your GCS device (tab, smarthpone, laptop) and fly.

Using RC modules like the FrSky DHT, it would be fairly easy to integrate an RC TX into e.g. ArduStation(-Mega). Or make a USB-PC interface. After all, the RC TXs are just embedded systems and usually with a much smaller chip than an ATMega2560.

The only thing you need is the respective PPM out. But that would be a different topic for a different project. My UxV-CS concept includes a ready RC TX :).

Updated my project page - added an additional layout draft with a 4.3" graphic LCD.
