You could just install OpenCV on a Raspberry Pi board and run your own performance tests. What counts as "real-time control" and image processing will depend on your specific application, so if OpenC …

This may be overkill, but some of the past work I was involved in was trying to detect a vertical line (a pipe) in the camera's field of vision, and navigate relative to it. The process was as foll …

You might find that the rPI boards are more durable than you expected. There isn't much mass to them, so a small amount of rubber or foam padding (to reduce rattling around) should be sufficient to p …

You are using a PID incorrectly. You are reading sensor values that in terms of acceleration, but you are using that to correct an error in velocity (without conversion). Your PID should be reading …

If you can convert the GameCube interface to be a USB game controller, this should go fairly smoothly. I used to buy used USB Xbox and Playstation2 controllers to control our underwater vehicles, and …

It sounds like you're experiencing a "brown out" caused when the excessive current draw from the battery causes a drop in the supply voltage. This is due to the fact that batteries have internal resi …

With an Arduino, you are guaranteed to have dedicated processing power for your balancing application. That said, the calculations for PID control are not terribly complicated and I would be very sur …

Alternatively, you could embrace the console commands instead of avoiding them, and still have it interact with your java program. This would have the advantage of continuing to deliver the video str …

Based on the videos, it looks like the answer is, unfortunately, "the test setup you have might be insufficient to say one way or the other". There is too much slack in the tethers to draw any meani …

If I'm understanding your architecture (from joystick to UAV) correctly, it is this: ${[\text{joystick}]-\text{wires}- \atop [\text{RPi}]-\text{USB HID}-}-[\text{Nano}]-\text{XBee}-[\text{UAV}]$ Yo …
