Hi all,

Thanks for the interesting reading you all have provided. I am about 60% done with my rover build but Ihave an issue I would like to get help on if possible. What setting would I change to increase the range of motion on the steering servo?

As soon I can get past this I think my build will be technically completely and then I can gather all my pictures and write down what and how I did things so that I may add to the group.

Humbly,

In the picture below are the 2 ranges that are reported by moving my transmitter steering stick.

Thank you u4eake, it worked great.  Would that same logic work on Throttle_min? If I set throttle_min to 50 would that mean no throttle?  I believe it was set to zero at default.  Again thank you very much for your help.

In my opinion setting throttle_min to 50 will keep the rover from braking or going backwards.  

Evaristo, have you tried adjusting the endpoints in your transmitter ?

I can't get the wheels to go round on my rover. 

    I'm using a Traxxas Russeler with a 2 channel TX, 4 channel RX and Xbee telemetry.   I'm going one small step at a time, and right now I only want to prove to my self that I have manual control.  So far I have steering but no throttle.  Also, if I actuate the throttle I lose steering control.  I can regain steering by re-selecting Manual in MP.

My connections, prolly rong.....

RX ch1(steering) -- APM input 1-- APM output 1 --- steering servo

RX Ch2 (ESC) -- APM input ? -- APM output ? -- ECS

Can  someone fill in the question marks?  and tell me what else I'm doing wrong?

Thanks,

Chris

Chris, are you following the instructions in the manual?

Comment by Chris Cuddihy on September 2, 2012 at 6:18pm

Chris A,  Thanks for the link, but that is how I have it set up.

Is anyone else using a FLYSKY TH-9X transmitter/ receiver combo with a full APM 1 and 3 axis magnetometor?
I am wondering as I got the end points finally extended out on the steering servo, but I have the following issues or concerns:

A. I am lost on how the receiver should be connected to the APM in order to provide input from the toggle switches in order to switch modes & add add way points. Yes I have tried both the cabling setup from the manual & from the original picture provided by Jean minus some connectors.

B. My pitch is correct when looking/tilting my rover but the roll is backwards (if I tilt the body left, the display goes right), is this a mounting issue or is there a parameter I can reverse?

Humbly,

I'm trying to run with APMrover10f with the magnetometer added in (for various reasons). What I'm seeing is that if the rover is pointed more-or-less north, the orientation in the mission planner looks correct. but as I rotate the rover to the west, the orientation deviates farther off. When pointed west, the mission planner displays about 310 degrees. At 180 degrees, the display shows 270. If I rotate it through 180 degrees, the display goes back to 90 and decreases from there.It appears that the useful range of the compass is +90 to -90. Is there an offset I don't know about, or is this something that has been fixed in a later build? I started looking at it this way because the rover just ran in circles. This is with the APM 1, and a DIY Drones magnetometer.

Hi Ben I am also running with the same equipment setup, so far I have been reading ok when using the magnetometer but I will recheck carefully. Check above for where I have my sensor mounted.

Comment by Evaristo Ramos, Jr. on September 11, 2012 at 1:32pm

so what does RTL mean?

Yes I know it probably a silly question.

But for a small update:

1. I got the Flysky TH9X operational after I hacked it and loaded up ER9X

2. Got the GPS working finally, I had to redo some of my solder points there are probably more but its usuable

I got a place to go test this evening so I will post up something this evening. If it all works then I will sit down and begin to write up everything I have done so far to add to the wiki.
