Hi! Did anyone have experience with these thrusters? It can be found under different names on Amazon etc and I was wondering if it is suitable for an autonomous boat project and how it compares with the BlueRobotics ones?

Hi I have Open Pilot revolution with Ardurover 4.1 mounted in a autonomous ROS Rover with Jetson Nano as companion computer. I have 2 cheap Beltian bm-180 and bm-220 that works properly connected via FTDI with Ucenter in windows, connected Revo+ Ardurover in Serial3 (flexi) and connected or not to windows via Serial0 USB. All works as should be.
My problem is the GPS will stop to work when is connect to jetson Nano and it boots. USB Serial0 (115200) works, serial1 (1500000b) works, but the gps will stop to work if is working or wont fix satellites if is connected after jetson boots, just a blue led flashing (it is red and blue when it works).
Uart in Jetson nano is connected J41 40 pin socket, with ground connected but not the 5V pin, it has the serial console service disabled as recommended to use the UART.Mention also those gps wont work in RPi4 via UART in linux without an Autopilot.
Does anyone have a clue why could be?, it stops to work after Jetson Nano load some software or kernel, is like a kernel module or service brake it. But it doesn’t look is a power, ground, or bad connexion issue. In Jetson Nano Im using I2C and SPI too, but if I disconnect them, still dont work.

@rmackay9 and @tridge
Having several users report that the hall effects sensor that comes with the futaba GV-1/701 governors does not work in Copter 4.0. The Futaba governor itself is not being used just the sensor used to measure RPM that comes with the governor is being used with the flight controller to measure rotor RPM. Discussion in this thread. The discussion continues in the thread and @jinchengde conducted a test where the software was reverted back to 3.6.12 and the sensor worked. Then loading 4.0.5, it caused an error. The firmware has the following error INTERNAL ERROR 0X2000000. From looking at the code, the error code refers to the GPIO ISR.
Hopefully one of you can shed some light on this issue and tell us how to fix it because I’m not sure if it is a hardware or software thing.
Thanks,
Bill

Hi Everybody,
my Tarot 650 quad twitches a lot on the yaw axis when it is still on the ground, but when I do the motor/compass interference test, the motors run very smoothly without any noticeable shaking!
please may you help me with the mighty cause, is it yaw rates or stabilize rates…?
thx in advance

I saw this page
https://ardupilot.org/copter/docs/common-leds-pixhawk.htmlI see the author changing all RGB LED states at will. I would like also to do that.
The reason for this is that I’m connected to I2C (as slave) instead of GPS here and getting the LED commands my self, so I want to test all the states.Could anyone help how this could done (force pixhawk all RGB led “14” states)?
Best

Hi.
I try to using lidar and it working perfectly if dron is horizontal ( not moving or slow moving ).
but if change angle ( fly ) then lidar see other point ( away ) and move down and after stop move go up.
If it can be corrected by actual angle ?

I am using the NEO_M8U UDR to acquire positional data for vehicle modeling purposes. One of the most important data input requirements is accurate road grade which is greatly influence vehicle power train load due the mean old gravity. Other UDR/ADR (Skytraq’s) includes a baro so I want to add the same functionality to the M8U UDR. Any suggestions would be helpful.
Thanks

I’m trying to use Matek 405 CTR with copter 4.0. I flashed without problems , connect and run through set up. But, when disconnecting and connecting again next day, looks that the controller can be connected but not data are showed in set up. It’s like no real comunication between controller and ardupilot
Only way was to flash again and start from cero. It happened several times. Could someone help?
Thanks in avance

I am thinking to next setup: on my hexacopter, I want to add only 4 motors on position 3, 4, 5, 6, which will be controlled by a Y split (with counter-rotating). And not duplicate motor 1 and 2. In total 10 motors, not 12. This way the yaw will be controlled by motors 1 and 2 (left/right), see setup from link. What is your opinion?

Interested guys should be USA, Canada or UK based & ready to sign NDA,. Collaborative Agreement as well as fund joint provisional parents after receiving PDF files with video of the design I have made!
Awaiting your response!

yeah I just switched radios uploaded the same profile only to find the Pixhawk has it in mode 1 for the radio. never heard of this before, who the @#%& flies or has a radio like that, but what’s stupid it that there is NO option to change this in the radio tuning section, WHY? The only mention of it bring up useless map config commands with no clear answer on how to change these modes.

I upgraded to the latest MP beta and loaded ardurover 4.1 dev on my Pixhawk 2.4.8. Ambition is to test Lua scripts. For now using REPL to get the syntax right.
My boat has dual motors, skid steerer (ch 1 and 3). And in addition remote controlled switches for lights (ch 2), a Kogger transducer (ch 4), a battery backup (ch 5) and a Raymarine fish finder (ch 6). Plus two servos controlling dual bait trays (ch 9 and 10). Everything works, using a flysky remote, Mission Planner or my own Carp Pilot app.
I want to create some new abilities and decided to test out Lua scripts. As a start I would like my lights to blink to give a visual indication when I open my bait trays.
The problem is that I cannot get the remote control switches nor the bait trays to respond to the Lua commands. The only thing I am successful at is getting motors to spin (also when boat is not armed) using:
SRV_Channels:set_output_pwm_chan_timeout(channel - 1, pwm value, timeout in ms)Motors spinning: No problem at all. But using similar commands for the switches or the Servos gives no result (also no error in REPL).
As stated, all switches and Servos work fine using the remote. And also works perfect using the set servo abilities in Mission Planner and Carp Pilot.Reading through the bindings I cannot find other abilities available for Lua than SRV_Channels. Either I have misunderstood something, or the abilities matching the set servo in MP are not (yet?) available for Lua.
Anyone that have some ideas?

Hi,
I’m new to Ardupilot/Arduplane and I’m currently building my first project using it. This is a fixed-wing (a Binary 1200mm from SonicModell) with a Matek H743-Wing FC with Arduplane 4.1.
I started to read the Arduplane documentation a couple weeks ago and I’m planning to read it entirely. (Thank you to those maintaining documentation).
My goal is to setup the plane so that it take-off and land automatically. I bought GPS/Compass as well as air speed sensors. I also bought an Optical Flow/Lidar sensor (Matek Optical FLow & Lidar Sensor 3901-L0X).
Here is my question: Is the Optical FLow sensor can be useful for a fixed wing? Should I disable it and keep only the Lidar sensor enabled? I think that the Lidar could help the plane to flare when landing however I’m wondering what the optical flow could do since I have an air-speed sensor.
Information I found about optical flow was mostly used with drones. I’m wondering if there is a benefit to use it with a fixed-wing.
Thank you for your time.

Hey Guys,
I tried to connect an new Cube Orange Pixhawk, fresh out of the Box to MIssionplaner.
I got an fresh Windows 10, actually Missionplaner an the current drivers. I followed the instructions for a first setup like here:
But i dont see the Board in the Device Manager. There is no connection, only the orange light is solid on.
I got an ChinaKlon Pixhawk 2.4.8, this one is shown up. But i tried nearly 2 Weeks to get a Firmware on the Board. If i plugged the board via usb on, only the orange LED starts, nothing else.
