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, I love the boat and it looks super sleek in the water!
I have a question for you. Were you ever able to adapt your sonar onto your pixhawk setup? I am doing the same thing, but have a pixhawk for guidance, then an arduino board for my airmar sonar. I can't for the life of me figure out a work around.
No I have not, but it would be nice as I believe the Network2000 is essentially CAN.
