The purpose of this project is to log sonar data of inland waters in order to increase the database of the GoFree Insight Genesis Social Map.
1. Light Easy to Transport
3. Capable of speeds up to 10mph
4. Capable of running up to 10hrs non stop
6. Monitor progress remotely
7. Highly Visible (safety)
Used the off-cuts of some old SurfSkis from a previous project to create a 2.9 meter trimaran design
Has a small enclosed console (removable for easy transport) to hold battery and electronics
Powered by a Yamaha 2hp 2-stroke outboard
Steering servo is via a vehicle wiper motor for torque using an old servo motor for potentiometer and output to a H-Bridge L298N.
Throttle is controlled by a heavy duty servo built into the motor directly above the carb.
Radio - Spektrum DX6i DSM (old)
Receiver - Spektrum AR6200 with Satellite
Up to this point the craft goes pretty well while being controlled directly with the radio as can be seen in this video -
Or should I say "lack thereof" as I am now in 'unchartered territory' and the cry for "HELP!" echoes across this board for assistance.
Pixhawk Power module
I2C extension bus
433MHZ Telemetry with 2.5DB Antenna
Receiver - Spektrum AR6200 satellite
Mission Planner (Laptop)
Pixhawk Main Outputs - #3 = rudder / #4 = throttle
Connected Pixhawk to Mission Planner
Calibrated Acc, Mag, Trans etc.
Completed Wizard - all green except for Arming of Autopilot
That is where I am now stuck.
Where do I go from here?
John, the rudder should be hooked up to output one and the throttle to output 3. What version of rover are you using and can you post your parameter file. The noise the pixhawk is making is the Failed to Arm tone. It could be for a variety of reasons.
David R. Boulanger
Nice project. Where do you live that you have zebras and old waveski's laying around? ;)
Oops! While fiddling with GroundControl things went wrong and now it won't connect to Mission Planner. :(
South Africa apparently.
Anybody know how to correct this problem? (Connect to Mission Planner after having this breakdown)
It's all crashed now as it won't even connect to Mission Planner any longer after tinkering with GroundControl and it did a update of sorts there.
I see you from the US bigkahuna. :-)
It appears as if the firmware is corrupted.
Can I reload directly to the micro SD from my PC?
Forget the micro SD card. That's for logging. Is the baud rate set properly on your computer. What firmware are you using? Is this a real Pixhawk or a clone?
David R. Boulanger
Yes, it is the same baud as before.
The first firmware I had was what I loaded via Mission Planner for Rover.
I ordered the Pixhawk on-line, how would I know if it is a clone?
I had never heard of a Pixhawk or an ArduPilot before a couple of weeks ago.
The problem came in after I attempted to load firmware via QGroundControl, and I think that was Rover too, but can't remember for sure.
It appears I am back in business!
1. Reloaded the original files that were saved to the original SD card
2. Changed USB port on my laptop
