Hi, 

I'm trying to get the rover to move in auto. Could someone post a small program with a couple of waypoints so I can see what a working program looks like? I've watched the videos and seen that just a flip of a switch sends the rover on it's way so I know it's me but I need to narrow down the list of possible problems. A working example would help a lot.

MP1.2.12 mav1.0

APM2

ublox

Thanks

Neil

Did you upload your waypoints to the APM with mission planner ?

In mission planner, go to the "flight planner" tab.  Enter some waypoints by clicking on the map (while connected to internet, so you have google earth maps).

Then select "write waypoints" and you should see a message showing that the waypoints are being written.

Then putting the APM in "auto" mode will start the car (be sure to limit throttle and to set THROTTLE_SLEW_RATE or it may be more lively then you'd like ;-) )

Thanks u4eake;

That must be the short virsion or is it really that simple? I tried all that for two days and finally had to take the truck apart because I borrowed it from a friend to try the APM. In the waypoint list I started with TAKEOFF, then a waypoint, then another way point and then a RETURN TO LAUNCH. You are saying all I need are the two waypoints and it will go when I switch to AUTO? I must be over thinking it.  An example program in the instructions would answer so many questions.

Hi all, I am not near my build due to being offshore on an oil rig enroute to the Gulf of Mexico, but i did get as far as being able to download the waypoints to the rover during the time I was home. I dont think my GPS was latching onto the satellites which stems probably from my soldering job which I am going to have to rework when I get home.

u4eake;

 On my desk I’ve connected the Rx and APM per JLN’s diagram and connected a servo to the #1 output (steering) and an airplane ESC and motor on the #3 output. I reloaded the Rover 2.20 firmware and calibrated the radio. Powered down and up to get the rover icon to show. All four channels work, as verified by putting servos on each output and moving them. The motor servo only works in the forward direction but that’s probably because it’s airplane and not supposed to reverse (?)but the crawler I had hooked up yesterday worked in both directions. In FP I added two way points and wrote them to the APM. I switched the MODE switch to AUTO (configured as flight mode 3) and nothing. I'm stumped.

Magnetic declination?  How is it entered?   I've enabled the compass via CLI,  but I don't know how to enter declination (12.25 in my neighborhood).    There also seems to be a way to do this in the Configuration menu under Hardware Options.  I've tried that but it doesn't stick.  Also, once Iv'e entered it correctly how do I know that it has been written to the EPROM?

Neil,

I believe that the GPS has to be moving to get an accurate fix and since it is not moving, I suspect that you will not see much if any steering/motor output.

Just a thought.

Neil, yes, it's that simple.  You don't need takeoff or return to launch commands.  Takeoff is for planes / copters and you can activate RTL with channel 7.

You do need to have GPS 3D lock before you can engage auto mode.  Since your gps in inhouse, I suspect that's why nothing happens : you don't have lock.  Try it outside, after the gps has obtained lock.

The gps doesn't need to move to get a lock, it just needs to be outside and have a clear view of as much sky as possible, so it can receive the gps sattelites that are orbiting the earth.

Chris, try the CLI command line interface to enter your magnetic declination

Hi All,

I know that this is a double post, but many of you are not in the ArduRover User Group and may not have seen this discussion and could possibly provide useful input.

For those of you who have your ArduRover working, I need some input from you concerning the setup of the radio channels.

I am using a Spektrum DX7 transmitter and a BR6000 receiver. I have the receiver connected to the APM1 R/C inputs per the diagram. I get the following R/C channel ranges in the MP:

Roll: 1109 - 1891

Pitch: 1110 - 1885

3 Way Switch: L 1148, M 1501, H1853

2 Way Switch (momentary): 1109 - 1892

I have the flight modes setup as follows: 1 Auto, 2 Auto, 3 Stab, 4 Stab, 5 Man, 6 Man.

Questions:

1) Do I have the flight modes set correctly for the ArduRover. I am assuming that the Stabilize mode is the Learning mode? I have saved the flight modes using the MP.

2) When testing the two way switch, the APM1 will lock up and requires a reset. Possible cause?

3) What is the difference between the actions in the Configuration Tab and the "Setup" button in the Firmware Tab in the MP?

4) After using the MP to load the latest ArduRover software and doing a reset in the CLI setup, what is the best approach to follow to complete the setup of the ArduRover. Should I start with the Setup in the Firmware Tab or go and use the functions in the Configuration Tab? The Setup initiated from the Firmware Tab seems to be very basic while the Configuration Tab functions are very detailed in the number of parameters that can be adjusted.

5) I have noticed that it does not matter what position the CLI switch is in on the Oilpan as I can initiate the CLI connection in either position. What position should the CLI switch be in for normal run operation? I think that it should be towards the servo pins for autonomous operation? Comments?

Regards,

TCIII

Does the code absoulutly requite a 6 channel radio?

Zero success. I can’t seem to get rover to do anything. Manual mode doesn’t work (well it dose seem to do something, some time, but never anything consistant.
I’m using Xbee telemetry.
I do not have a 6 channel radio (3 posit switch and 2 posit switch). I have tried a 5 ch radio ( 2 posit switch for landing gear) and a 2 ch radio.
Does the code absoulutly require a 6 ch radio?  Or does the code need to be modified?
