Hi Emlid community
I just begin to interest myself into a drone construction!
After looking the different feature of Navio+ I think it’s the best solution for me.
But i just want to be sure of one things: I want to turn my Raspberry Pi into a wireless router and I want to control the Navio card with the Wifi of the Raspberry Pi. It’s possible?
Sorry for my English!
Yes but here are some points to consider:
- There could be extra latency between the control movement and the reaction, compared to a RC transmitter/receiver. Don’t use such a setup for racing or low/proximity flight.
- If you already have a radio transmitter, the cost of a basic receiver with CPPM pass-through is insignificant and very useful at least for takeoff, landing and backup use. The new ones are also very small and light.
- You need GCS failsafe set so it will not fly off if you lose the WiFi signal, and set to a height higher than anything you plan to fly around.
- The joystick support in Mission Planner is more advanced, so maybe you should use that as your GCS.
- If you use standard WiFi equipment the range will be limited, more than a RC transmitter. You should get a high gain antenna for the ground station and a decent USB dongle (with necessary drivers) for the drone.
- The USB ports don’t provide enough power for most newer WiFi dongles by default. There is a config.txt option to increase the power on the RasPi but you may also need to wire-in a separate supply (some people even put a USB hub on board). See: http://raspberrypi.stackexchange.com/questions/27708/is-setting-max-usb-current-1-to-give-more-power-to-usb-devices-a-bad-idea
- If you don’t use WiFi for control (install an RC receiver) then it could still be a viable alternative to the 3DR radio for GCS telemetry and instructions.
Thank you for your quick answer! I take into account your advice but I have to control the drone with wifi.
And I have another question: Have the navio+ the capacity to control a drone with 8 ESC ?
There are 13 PWM outputs on Navio so 8 ESCs are no problem I presume the configuration you are using is supported by APM, e.g. octocopter or X8/octaquad. http://copter.ardupilot.com/wiki/connect-escs-and-motors/
