"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…"

"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."

"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…"

"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…"

"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…"

"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…"

"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…"

"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,…"

"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…"
