- I want to know how to improve.

is there any way to work on code without being near the robot?
We use Beta 8397's incredible https://github.com/Beta8397/virtual_robot as well. We actually program our robot into it so we can use our code as is. That is not exactly for the faint of heart, but it is an option. I suggest using one of the built-in robot configurations and modifying it to learn how.

Any hardware that's not $700 that can run FTC code?
Agree. We have used virtual robot for programming practice and training new programmers.

New to Coding
Agree with this. Also, you might want to check out virtual robot, which has built-in support for the "Learn Java for FTC" book and will allow you and your team to start programming without needing access to an actual robot. We have used both of these with some success.

Does Amazon Corretto 8 JDK include JavaFX?
I maintain this JavaFX project. It runs fine using Amazon Corretto 8 JDK on every Windows system I've tried it on. A user with a MacBook recently posted an issue (package javafx.application does not exist), which he or she fixed by switching to the Bell Liberica 1.8 dev kit.

Simulator that works with roadrunner?
Another +1 for Beta's excellent simulator at: https://github.com/Beta8397/virtual_robot

A question
We have used Learn Java for FTC with some success. In conjunction with this, we also use a virtual robot simulator which has support for the "programming board" hardware construct in the book. The simulator allows you to learn programming without having to buy an actual robot. Both of these are free.

Virtual Robot Simulator
I am using the virtual robot simulator(https://github.com/Beta8397/virtual_robot) and can't get it to run my op modes. When I click init it does nothing. The demo scripts work but mine doesn't and I'm not sure why. Can someone please explain why this might be happening?

Using the webcam on the robot to record videos.
you can record from the robot's POV with openCV: https://github.com/OpenFTC/EasyOpenCV/blob/master/examples/src/main/java/org/firstinspires/ftc/teamcode/PipelineRecordingExample.java

Getting raw camera data
The SDK provides a UVC driver for webcams; it does not provide anything for phone cameras. If you'd really like to write your own implementation, you can use parts of https://github.com/OpenFTC/EasyOpenCV/blob/master/easyopencv/src/main/java/org/openftc/easyopencv/OpenCvWebcamImpl.java as a reference (which uses the SDK UVC driver), but do note that writing your own implementation means you need to write your own code for a live view, as well as handle threading etc.

Where do I put our c270 Webcam to plug it in and configure it to our robot?
getting basic computer vision working is pretty easy with EasyOpenCV and the AprilTag extension.

Is it possible to upload code from Android Studio faster?
Apriltags, yes. You just upload the aar files using the OnBot interface. You can get them from the OpenFTC project: https://github.com/OpenFTC/EasyOpenCV/releases/tag/v1.5.2 https://github.com/OpenFTC/EOCV-AprilTag-Plugin/issues/4

what is the best way to read a symbol on the signal sleeve
We used the example for https://github.com/OpenFTC/EasyOpenCV/releases. Our fork is from the official FTCRobotcontroller repository with extensive slipstreaming. You are welcome to view our repository at baqwas and provide feedback to our programmers who are continuously learning new techniques. I'm sure that they will learn something from your feedback too.
