heliboy replied to heliboy's discussion Mission planner waypoint accuracy ? in ArduRover User Group
"TCIII

Thanks. I have done so. Let's see what reply I get. Also, I understand that Ardurover 2.50 is the latest production release. Can't seem to find the source on Github. Do you know where it is ? Thanks.
BTW: I believe you are spending most of…"

In the past MP waypoints were only 1m resolution. I read on a thread that this was being changed to allow higher resolution (cm) waypoints. Does anyone know if this was done ? Are there other GCS programs with higher res than 1 m ? Thanks.

Based on some threads a while ago I understood that waypoint accuracy in MP was 1m. Andrew stated that there was work in progress to bring this down to cm level to match some of the new higher accuracy RTK receivers. Does anybody know if this was…

heliboy replied to Jimmy Kan's discussion Rover spin around in Auto mode in ArduRover User Group
"Same problem. Something is wrong with 2.50. Used to work fine but now only circles. Someone with intimate knowledge of the changes made is the only hope. It is nice to know I am not alone. It not nice to know that it just stopped working."

heliboy replied to Robert Kyamoto's discussion Rover goes in tight circles when in Auto and RTL mode. Error Compass Variance Alert. in ArduRover User Group
"Same problem. Something weird is happening. My bot worked just fine but all we do is do tight circles. Gps lock is fine. No changes made. Sucks. Wife is mad that I am upset at all the time wasted."

"Same problem after it worked well for months. Reflashing 2.50 does not help. I set everything back to default. Then it works. Open source is fine until it does not work. Not sure pixhawk/APM is reliable for real use. Let us know if this helps. My…"

heliboy replied to heliboy's discussion Gps heading versus compass/imu heading in ArduRover User Group
"I will put up some video later today. I tried some ideas including increasing the exf gps noise parameter but was not much use. Then I disabled the AHRS (set to 0) and the rover was much much more stable. I adjusted nav1 damping and period so it…"

heliboy replied to heliboy's discussion Gps heading versus compass/imu heading in ArduRover User Group
"Compass_use is set to 1. Darius's idea of just using inertial heading between waypoints is interesting. Clearly I do it have to worry about wind drift - the machine weighs 1500 lb empty + max payload of 1500 lbs. But you need the gps to work out the…"

Work continues slowly on my monster robot. One of the problems is that it moves very slowly (2-3 meters/min) and I think it weaves because the gps heading varies a lot when moving slow. I think the compass/imu heading should be more accurate. It…

heliboy replied to Rolf Blomgren's discussion APM MavLink to FrSky X8R S.Port converter
"I found this very useful to decode MAVLINK messages from Pixhawk. Thanks. My latest problem is while this was very effective in reading data how can I set parameters on the Pixhawk using MAVLINK. In other words the reverse process. I have spent…"

heliboy replied to heliboy's discussion DUAL sonar on PIXhawk in ArduRover User Group
"I got it to work. At least the first sonar. One of the issues now is - I can see and graph the first sonar but there appears to be no way to see the second sonar ! I cannot seem to get the CLI to work properly on the latest MP. It connects but then…"

heliboy posted a discussion in ArduRover User Group
I am trying to follow TCIII instructions for how to connect dual sonars to a PIXhawk. First of all in MP the sonar options are gone and now we have RANGEFINDER. According to TCIII the pins are 12 and 13 ( 3.3 v ADC) but the MP wants to use pin 15…

"jean-luc:
 
You are absolutely correct. After a restart and a hour later the position was normal. Thanks. I will look into Dell ATG."

"Great job ! Very impressive. But work on the dead man switch. I have a 2000 lb diesel powered tracked bot and I am very glad I designed 3 independent kill systems from the begining. Everything will fail. Cables get loose, switches get stuck,…"

I took my bot out of storage after a few months (too busy for fun !). Updated MP to 1.3.24 and took it outside. Link is fine and  I get 13 sats and everything seems good but the location of the bot on th MP flight data screen is off by at least 200…

"Thanks for all the help. I will try to mount the sonars later today. The need to trigger each one separatly is a pain and will cause response delays. My application is to crawl along a fence line. I was wondering if I could make two whiskers (steel…"
