I'm working on a research project for a university in Peoria, IL with an omnidirectional ground based robot. I'm wondering if the APM is a good choice for a brain for the robot.
My main question is can I use the APM without any shield at all? I know

I added a current sensor (details later).
When I run APM terminal and invoke test] current I get good numbers reported for battery voltage, current and mAh keeps climbing.
When I switch to telemetry and HK GS, battery voltage is re
Its just for curiosity, my quad is working fine now, but I measured in the scope the PPM output from APM to ESC and I noticed that its is arround 3V, is it common? shouldnt it be 5V?

Is it possible to scale it up to lift a couple hundred pounds? As far as I know, it has not happened but

I recently got time to set up an EPI-OSD on my MK based multirotor. I have also bought an EPI-Strom and a USBprog to flash the various chips.
I have hit my first hurdle. The EPI board is running the EPI-OSD firmware whereas the EPI-Strom (Cu

I made this basic Unmanned Ground Vehicle from scratch last year.Its controlled through hyper terminal on Windows( after I connect the transmitter/ remote control to the serial port ). The thing is that now I want to control it on some bet

During my ground tests, I found that the velocity measurement (in North-East-Down format) of UBlox GPS is not accurate as I expected. The experiment is like this:
1. fix a UBlox GPS unit on a trolley, which is initially stationery;

It seems that CH4 dead zone (YAW) is very large (1000) compared to other channels.
The problem is that this value is not substracted from the yaw output.
So when you push the Yaw stick, you need to push it a lot to get a Yaw action, and this action

Hey Guys
Okay Simple requist , is time for me to upgrade, I have a 3meter WS FG glider, Raven and Skywalker now im looking for ether ARF or RTF airframe that will make Awesome UAV airframe.

I always thought the front was the side of the boards were the GPS connector is.
I'm not using that. I'm actually using Rusty's frame.
The pics in the manual show that the board is actually at a 45 degree angle when using the X frame.
Here is the pi

I've had a look at the simulation (HIL) capabilities described in the manual and that seems a really great way of improving one's flying skills safely. However, is it only applicable to aeroplanes at the moment?
I am still at the stage of lear

I mentioned in another post that I use a pre-flight checklist to help prevent avoidable accidents in the field (e.g. forgetting to put TX aerial up) , and Chris suggested I posted it, so here it is:

Hello, has anybody been succesful in obtaining a decent altitude hold?In Ardupirates it was working farly good, but I can't seem to find the right PIDs.It doesn't correct quick enough.Even with a lowered P it goes up and down till it eventually stops
