"The team talked about using a neural net and one of the obstacles that came up was  the need for sufficient training images. Did your team recreate the course to get the training images? Were you able to use video from last years competition as…"

"Glad to hear that worked so well! We will definitely look into using a neural net. Any advice?

Also, do you have any experience in fusing computer vision with distance information (from a LiDAR or stereo vision)? Most teams in this year's RoboBoat…"

"How did the neural net work out? Was it able to compensate for different lighting conditions? That seems to be one of the big problems with vision systems.

Does your team have a website that is still up?"

"Since out motors speak RS485 I've been looking for a way to change the APM:Rover code to send the needed packets to the motors. Keeping TCIII suggestion of using an Uno to read the PWM output from the PixHawk and send it to the motors as a backup.…"

"Gerald,
Thanks for the link! It was a great read!


Are you still working on the project?
Have you created a boat simulator? I ask because we have looked into it and it is no trivial feet.
Have you been able to get ROS working with APM:Rover? I have…"

"@TCIII,

We were planning on using the serial 4/5 or the CAN ports.

"@TCIII

Why use an Uno and not take the RS232 from the PixHawk and use a converter? Wouldn't an off the shelf be more reliable than an Uno?

-Jake"

"@Thomas
Can you say more?
We chose the PixHawk because of the ardupilot community around it and its use of built in sensors. Do you think ROS will be difficult to implement on the PixHawk and if so, why?

"Been working on hit rad and yaw parameters for waypoints and we haven't found anything different from Tom's observations: hit rad and yaw have little to no effect on the mission.
It would been helpful to know if these parameters actually do…"

"Ran,

I've flown some auto missions on 2.8.1 but most of them have been with 2.9.1b. I can tell you that 98% of the time we have had no significant problems with 2.9.1b.
But, there was a time when the GPS suddenly thought it was about 250m from…"

"SOLVED!

As Dave_C wrote, it was a loose ESC connection. One of the female bullet connectors on the ESC wasn't connected to the ESC and was being held  on by the shrink wrap.
 
Replaced the ESC and just had a bunch of scuessful Auto flights."
