I need help with an autonomous speedboat project
@zelos48 wrote:
Hello everybody,
I am currently planning to build an autonomous speedboat with a length of 170cm. Unfortunately, I am still a beginner in the field.
The boat is steered by a Z-drive, which makes the curves narrower the higher the speed. I have set a cruise speed of 8m/s. My problem now is that the boat throttles the speed at the waypoints to 4m/s. However, it should drive a consistent speed. Which parameters do I have to set for this?
Let me know if you need more information.Thank you in advance for your help!

Extern GPS with compass, NMEA messages
@bok555 wrote:
Hello
I have connected a Hemisphere V103 GPS Compass to BBBlue ttyO1.
ArduPilot receives GPS messages fine.
The GPS Compass delivers higher quality heading information than the internal.
How can I get ArduPilot to accept the Compass NMEA messages (GPHDT) ?
If nessecary we can send GPHDT messages to another serial port.

Unable to change mode to "AUTO"
@Guillaume wrote:
Hello everyone,
I’m stuck with an error and I’m asking for your help…
TL;DR : Cannot change to “AUTO” mode and don’t know where to find relevant info about the error I get, “Flight mode change failed”
I want to control a boat using QGroundControl to do autonomous missions using GPS.
I have configured my autopilot (ArduRover 3.4) as a boat (Frame_class=BOAT) and made several adjustement to make it work with my controller (Taranis x9d plus). Everything seems alright in “manual” mode but I cannot make it to change mode to “auto” or “guided” (from QGC). I keep getting the message “Flight mode change failed” but without any other information.
Moreover, I didn’t manage to get any relevant log using the console and I’m stuck trying to get some information pointing out the reason why I cannot switch to “auto” mode…
I hope I made myself clear enough and I will gladly provide more information that could help understand my problem
I have to admit I have little to no experience in ArduRover although I succesfully configured several UAVs with the pixhawk firmware…Thanks in advance for your attention !

Arduboat with 3.5m boat and yamaha 6hp engine
@canterobb wrote:
Hello, after a long time of reading many topics in this forum I have dared to create a new topic.
I decided to build a boat with a gasoline engine after seeing this
although in my design, I made some modifications to be able to use my boat in waters with a bit of waves.
I built the boat with a length of 3.5 meters, and I used a yamaha 6hp engine that I already had.
the electronics so far is very simple, a pixhawk 2.1 with ardurover 3.5, a pair of radio rfd900, a taranis x9d and a pair of bec.
The accelerator is in charge of a servo savox of high torque and waterprof.
I have done tests in the sea in 2 occasions with the control in manual form, the first time it did not work very well, because for steering control I used a servo that although it had a lot of force was very slow.
8 "Stroke: 115 lb Thrust Linear Servo
https://www.servocity.com/hdls-8-50-12v
This servo did not protect it well and finally it was damaged by salt water.
then I asked for another servo similar, a little faster and with a little less push
8 "Stroke: 25 lb Thrust Linear Servo
https://www.servocity.com/hdls-8-2-12v
also perfect the place where the servo is located so that no water enters and install a teleflex to transmit the thrust of the servo to the motor.
on this occasion the boat worked very well manually, I had complete control of the movements, this was very nice.
although in an automatic way it did not work very well, it was normal to adjust the autopilot, so I took the boat out of the water and returned happily to my house with the intention of the next day to continue the tests, but made the mistake of leaving the boat on .
the next day the battery was dead, and as I had left the boat turned on so long were the logs of the previous day and the worst thing is that my steering servo did not work, I started the engine and the battery quickly took charge, but the servo just as fast moves of push and pull, it moved only less than 1cm, wrote to servocity because I suspect that the driver was unconfigured.
I have dared to create this thread because I hope to receive help from the community, someone knows if it is possible to reconfigure this servo.
or is it better to buy a new one? (They are not very cheap) and I think they are very delicate.
It will be that I can find a servo ready to use, more robust.
will it be better to make a customized servo?
the reliability of all the components is important since it is a big boat, and although I use it on a very lonely beach, I would not like to lose my boat.
thanks for your help.

UDP communication to fixed port
@Knaldgas wrote:
If I understand it correctly, the option ‘-C udp:<target_ip>:14550’ will let ardurover send MAVLink messages to the targets port 14550. The target is then supposed to send back messages to the source port, whatever that turned out to be.
We’re trying to hook up ardurover with 3. party software. That software expects to transmit MAVLink messages to ardurover at a fixed UDP port.
Can we set-up ardurover so it listens for MAVLink messages on a fixed UDP port?

Upgrade to Pixhawk Questions
@copterguy wrote:
Hi All,
I am currently using APM 2.8 with the latest beta of Ardurover, Dual APM2 HC-SR04 range finders, GPS, etc., on a Frankenstein vehicle setup as a test bed for the Ardupilot software. Very nice, btw, thank you.
My future plan is to build a new rover from the ground up using a Pixhawk 2. Is my understanding correct that I can still use 2 range finders, one using the IC2 interface and the other the analog interface of the Pixhawk? If not, is using one MB1200 LV-MaxSonar-EZ1 sufficient? Perhaps LiDAR? I am curious to what the experienced builders are using.
The rover will be used indoor and outdoors.
Any suggestions are appreciated. Thank you.

Trouble connecting USB to Windows PC

I’m having issues connecting my Kakute F7 board to my PC via the USB port. Mission Planner (and devise manager) does not recognize a connected com port. I assume it’s a cable issue but I tried a couple that I use for connecting to BetaFlight boards and they don’t work either.
Anything I’m missing here? Trying to download some logs and it’s taking forever over the Sik radio.

Vehicle does not drift inside of Loiter Radius
@SUI1271 wrote:
Hello,
We are using a skid steer boat. The main task of the boat is to stay as precisely as possible at a predefined position. This works excellent as long as there is some light or strong wind which pushes the boat always to the leeward edge of the Loiter Radius.
But if there is absolutely no current and no wind we expected the boat to switch off both motors as long as it is inside of the Loiter Radius. Our LOIT_RADIUS = 5 m, and LOIT_TYPE = 1.
We noticed that the boat moves very slowly from the edge of the Loiter Radius towards the Loiter Center and continues in the same direction until it reaches the edge of the Loiter Radius on the opposite side.
Do we misinterpret the information “Vehicle will drift when within this distance of the target position” when we expect the motors to be switched off?
Any help is appreciated

Blade Boat support
@KG_Fairbarn wrote:
I was finally able to complete a decent mission with my new build. I’m calling it the ArduBlade. Not sure how long I was out for sine it seems the log didn’t work but it was about 10 minutes. Ended up getting fouled in the lake weeds and had no steerage.
I created a few missions using q ground control. 2 survey patterns with a few lines, an octogon, and messed with the “go here” function for a while. The log only recorded one minute of data. I didn’t see any write error messages. What could be the cause of this? I’m recording on the Kakute F7 onboard SD card with a class 10 32GB micro SD card. See log below.

Skid problems V2
@ecabanas wrote:
Hi all again,
Today I tried to put my skid rover into auto mode and it has been a disaster again.
First of all: in manual mode forward and backward goes perfect, but when it turns left turns ok, but when It turn right the rover makes a reverse throttle…very strange, better see the videos.
Later I just tried the auto mode, a straight line to waypoint 1, pointing to the north and the rover went to the east without any sense
I attached some videos and the logs

Skid steer rover not executing mission in auto flightmode
@Diego_Rivas-Lazala wrote:
Hello, everyone!..Once again. I need help with my skid steer rover because the mission planner shows that the vehicles can go into auto mode but the rover doesn’t move while the mission is being “executed” as stated in the messages tab of the flight data. The only movement I can receive other than perfectly being able to drive the rover in manual is if I hit RTL on the flight data screen, but if RTL is in the mission the rover doesn’t move at all. One issue is that when I do hit RTL the rover just goes in a circle nonstop. I’m running a 6 wheeled skid steer rover with a sabertooth 2x12 (dip switches set to upside up [DUUDUD]) and on ardurover 3.5. Looking for any advice! Please!
Here are my parameters and data flashlogs from earlier today when: https://bergenorg-my.sharepoint.com/:f:/g/personal/dieriv21_bergen_org/EgEUe6Db_NNBvPf4Eb1QGAcBalY1w19061I__u_ZlWZVkA?e=caYXAY

Hi everybody,
Can I set a Parameter to slow down the cruise speed before reaching the target?For example, 20 meters before reach the target slow down to 50% of the cruise speed, 10 meters before reach the target slow down to 25% cruise speed,
5 meters before reach the target slow down to 10% cruise speedOr Dynamic from 100 % in a raduis of 30 Meter to 0 % on target.
@rmackay9 eventually a feature Request?

Hi,
I´m trying to set up a fish feeding boat for fishing. Everything seems to work, but i can´t set up servo functions in the servo tab. For every function it just says diabled and can´t be changed. Any idea what i´m doing wrong?
I also can´t set it to boat mode.
This is my first time using ardupilot, so its probably just a dumb mistake.mini APM 3.1
