"I will probably buy two keels from other boats and give them a try.
No wind vane. On such a small boat as this, there is no way a vane could be expected to survive and still be accurate. So, the sail will be sheeted to travel 30 degrees to…"

"Yeah, i think so too. I have looked at other keels and hoping I can use a Soling 1 meter or v32 keel. Not sure how that would affect the balance though."
Hey everyone. A while back I integrated a pixhawk into a RC sailboat. I was surprised that it actually made all the waypoints without too much struggle.pic.twitter.com/IRGjtzTz9hSince Edgar won't launch until later this spring, I figured outfitting…

The pixhawk runs the latest rover code without modification.
Arduinos control the pixhawk (arm\disarm - manual\auto mode - update waypoints), sensors, modems, etc."

Just a quick update on the research platform. I launched it on its final shakedown cruise into the ocean off the Central California Coast. Once out in the ocean, it completed a 30 mile circuit (15 miles straight out to sea, 15 miles back).One reason…
"I have been experimenting with STEER2SRV_TCONST but getting such a large boat out onto the water for an empirical test can be daunting.
I think this would be a perfect job for simulation software."

Working on a seond project. this one uses a linear actuator to steer a rudder on a 5 meter boat.The travel time for the actuator is .5"\sec.The stroke is 1.96"My concern here is that with the slow travel time the servo might not be fast enough to…
"@Grant - It is narrow and counter weighted as I built it with the understanding that it will be flipped and capsized more then a few times on its journey in the Pacific Ocean. I built is a tough as I could - there is not a lot space for water to…"
"@bigkahuna - Thanks for the links! I have an email into NOAA."
Finally was able to get the project back into the water after a 2 month hiatus. I have been trying out different props. One is the standard manufacturers issue and the other has more torque. I launched during a flood tide with winds out of the East…
Finally was able to get one of the bots out onto the water. For this test, I chose an area of San Francisco Bay that is subject to strong currents during the tide changes. As the tide was going out, the current was about 3 knots. The bot did fine.…

Very cool interface.
Shoot me a PM if you would like to see the web interface I have setup."

Power breakdown as follows:
25% 4 amps
50% 9 amps
75% 14 amps
100% 22 amps
At 25% the motor was using about 4 amps which gets me about about .5 to 2 knots on the intex in SF bay depending on current, wind and sea condition. So I figured Edgar…"

I actually am looking at your thrusters for another project I have. Congrats on a successful Kickstarter Campaign!
Now that rover does skid steer, I can think about dropping the rudder on the next build!
Capsizing:
