Problem with the AP_InertialNav

Started Mar 31 0 Replies

I am using APM 2.5 with GPS and I am trying to get data such as position and velocity from AP_InertialNav using get_position() and get_velocity(). However, I noticed that the position and velocity…Continue

No throttle signal, Arducopter 3.1.2, Xplane, simulation

I was using arducopter v3.1.2 and xplane 9 for the simulation. My problem is that there is no throttle signal when I move my transmitter throttle stick. The other sticks have got no problem as the…Continue

How to repair APM 2.5?

My APM 2.5 is spoilt recently due to short-circuit when I was trying to measure the battery voltage with my own potential divider. Currently, the APM cannot be detected by the mission planner and…Continue

Poor Orientation( apm 2.5)

Hi,    I have tried to test the orientation data calculated by the AHRS_test from the library and I noticed that the yaw, pitch, roll values just drifted away even when APM 2.5 was just left…Continue

Problem with the AP_InertialNav

I am using APM 2.5 with GPS and I am trying to get data such as position and velocity from AP_InertialNav using get_position() and get_velocity(). However, I noticed that the position and velocity provided by these 2 functions are not very accurate. The values keep fluctuating and never converge even my APM module was not moving. Does anyone come across this problem? Any solutions?See More

"Good news! I have just solved this problem! You must arm the motors us a real flight. First of all, we have to disable the Arming check option in config/setup->standar params. Then you can arm the motors clicking on arm/disarm in flight…"

"Hi all! I have the same problem. I think it is because throttle gains but I dont know exactly what to change.  "

No throttle signal, Arducopter 3.1.2, Xplane, simulation

I was using arducopter v3.1.2 and xplane 9 for the simulation. My problem is that there is no throttle signal when I move my transmitter throttle stick. The other sticks have got no problem as the mission planner is able to detect the signal as I move the other sticks. I can't take off as the throttle stick does not give me any response. the propellars in the xplane do not move when I move the throttle stick. Have anyone come across this problem? May I know how can I solve this problem?See More

"not sure, the problem is still not solved yet. I haven't tried repairing it as I am not too sure which components on the board are the fuses."

"it is normal for the computer to shut down when it detects a short on the usb bus. hopefully you only damaged the fuses and/or the diodes. If so, you'll have to rplace them using a good soldering iron."

"yes, those are the fuses, and there are also some diodes near them (check schematic). I would test all of these components with multimeter."

"I was using A0 pin to measure the voltage. The APM 2.5 was powered by ESC/LIPO and at the same time connected to the PC to monitor the output. The short-circuit somehow happened when I accidentally pushed the cable and the cable touched the APM…"

"refer to this schematic... http://diydrones.com/forum/topics/apm2-5-5v-vcc-schematic you can test the fuses with a multimeter, test for continuity/resistance across the fuse terminals... there should be little to no resistance..."

"Is the fuse located right beside the diode near JP1? How do I know whether the fuse is blown or not? I did not notice any unusual thing on the fuse."

"where specifically did the short circuit occur? did you already check the 'fuses' on the board? Though, if you're getting power to the board, I wouldn't think it would be a blown fuse... refer to the APM 2.5 schematic to see…"
