OpenCV marker Detection Help
If you look at the code from line 118-135 from this file, you can try to adjust it yourself. It currently replaces a rectangle, if it is possible to make a larger one.

OpenCV Detection Example
The lower and upper are the "colors" that it searches for. So green isn't 1 value, you have light green and dark green and colors in between, which is why you need a 'Range' of colors to detect. There is a picture added on Github . The origin is (128,128) and left under is (0,0) and right up is (255,255). The Y should not be changed at all. This video helped me a lot with understanding the YCrCb Colorspace. If it is still not clear ask me again, I can go more in detail.

Robot stopping randomly
It could be a memory leak somewhere. If you use FTC Dashboard, make sure to update to the latest release (0.4.7) as it fixes a memory leak when the dashboard is installed but disabled, which was affecting some teams at competition. If you are using vision code, make sure you are not creating new objects every loop cycle, which will fill all system memory until it crashes. (We have had this issue multiple times in the past when we are using OpenCV-based detection, it's an easy mistake to make.)

Can you Run Op Modes without a separate driver hub?
Yeah - just run it from the dashboard. https://acmerobotics.github.io/ftc-dashboard/

TeleOp Code recurring disconnect issue
The SDK has a built in camera stream, which isn't great, but it can help. If you are willing to go a little more complex, look at ftc dashboard It has a few really great features including the ability to live view the camera stream and allowing you to set up variables so you can update them on the fly.
