Hey question. Am i right in saying if you want to have servos, you have to connect either the main battery or an additional one to the servo rail? If this is correct, what is the max voltage input into the servo rail? (In other words, whats the biggest sized battery i can plug into servo rail) For instance, Is it 5v like the pixhawk, or can the servo rails take in 12v?
Hola Bzeug !. Ya he recibido mi kit Pixhawk 2.4.8 de Aliexpress Tengo problema con la instalacion del firmware fmuv3 rover que es el que me indica debo descargar Tengo muchas preguntas que hacerte tu que ya tienes esperiencia , que clase de bateria debo ponerne ?. Puede servir una de 5v de un powerbank ?. En su cable aun lado pone bateria y en otro creo esc no tengo ahora a mano el pixhawk perdoname tiene el kit el gps M8N Yo compre en otro sitio el TFmini plus plidar de beneveke pero estoy con la duda donde se conecta y como conectar mi receptor FrySky FS iAB10 y el Cytron MDDS30 al pixhak estos dias consegui o eso creia instalar firmware ya que en mission planer no podia salia error siempre , probe en el QGroundControl y pulse en px4 firmware.. Igual cometí ahí un error.. En la tarjeta microSD solo se guarda las coordenadas de las misiones que quiero haga ?. Cada vez que abro el Missión planer debo de nuevo hacer todos los pasos de instalar firmware calibrar brújula etc ?. Cuando tenga ya por fin instalado el firmware Rover y todo lo demás que te decía receptor emisora y el mdds para controlar y dar corriente a mi robot , cuando lo lleve al campo al conectar al Pixhawk la batería el se pone en marcha solo o debo pulsar en botón luminoso que viene con un cable de creo casi 10cm conectado para que se ponga en marcha ?. Perdoname son tantas preguntas y dudas que me lío Recuerdo alguien me dijo no hace falta luego llevar ordenador detrás con la telemetría que el pixhawk ya con las misiones cargado en su microSD ya se pone en marcha pasando por donde le he puesto como misión esto es correcto ?.
Hola, soy un novato y me gustaria saber ¿que tipo de motores y baterias usarias si por ejemplo necesitras transportar con el tanque robot 100kg de peso?,gracias.
how do you map a radio channel to a servo in ardupilot? I've got ch1 moving servo output 1 (ground steering) and ch2 isn't doing anything, but it works in the radio calibration page. I've tried setting #2 and #3 to throttle but there is no movement of the green bar on the servo output page. I'm making a skid steer too, when i change the servo outputs to throttle left and throttle right then I don't even get the green bar moving on ch1. There's something about the servo function that's assigning the chanel to the radio?
I whish I had a good answer. One with only one microprocessor in it (no extended serial ports). Basically find a minimal one, any of the more feature rich models will likely have an additional microprocessor that adds more serial ports. When I built mine I could not get the Rover firmware to drive the motor controller and I suspect it was because of the extended serial capabilities that the Rover firmware didn't know how to use properly. I hope that helps.
I'm running into this issue as well. Holybro says they will release a new H7 variant to replace the PX4 Mini in 4 to 6 weeks. Working on a tank rover and a marine drone that uses differential thrust, so they both drive basically the same way.
I have a Holybro 6x mini running ArduRover 4.6.dev controlling a differential steering lawnmower. I am using a Sparkfun ZED-F9P as a Rover on the mower and as a Base Station for RTK GPS.@@ride_panzer
thank you for the prompt feedback a few weeks ago. Quick Question on setup. So ive gotten everything running and communicating ok my only issue is setting the steering up for tank style. Any suggestions or links you could provide in helping me with this step? What page or settings do i need to change? Thanks (am using a Pixhawk 4 mini ) same setup as you. Cheers!
ok so I have configured the what i believe to be correct settings not sure. I am using (pilot mode 1) for skid steering. i wanted to see how you are steering. I found I could only have 1 channel run the throttle (forward and backwards) and a separate channel control the steering. Strange on my esc i had to switch the wires on one of the motors backwards? Did you have to do this to? I will be testing the auto this week when I get time. If you have any suggestions on tuning settings or other settings you thought were a good idea that would be great.
whats your take on using standard GPS from holly bro vs this rover version? The rover version is 400 bucks vs the smaller 80 to 100 dollar gps. Whats your take on this? Thanks again your videos are awesome!
Did you get the GPS “POINTS” ACCURATE WITH YOUR ROBOT WITHIN 3 TO 4 INCHES CONSISTENTLY? IM DISABLED AND MAKING A MOWER TO CUT ACCURATE PATTERN WHILE CUTTING AROUND O BJECTS (TREES, BUSHES, TREE ROOTS) ETC. THX!
I don't know the exact precision but I would say less than 6 inches consistently for sure. RTK is the only way to get any amount of real precision and this RTK system even with no base station did a very satisfactory job for me.
Hello Bzeug , I 'd like to come visit to get a first hand look at your robots... I'm in MB , canada, perhaps you can PM me privately.. and tell me where you are.
There is not anything custom. I just load up Ardupilot Mission Planner on my laptop which has the USB 900mhz radio connected, I use that COM port to connect to the other 900mhz radio on PX4mini. Then I can use Mission Planner to flash the "Rover" firmware to the PX4mini. I had to go through the calibration procedure, but other than that I did not change much of anything beyond the stock parameters. I should do a video about it, because I know I am already forgetting some steps. The problem with making videos about software is they are time consuming and become obsolete relatively quickly. The good thing about such a video is that I can watch it myself to remember all the steps.
