Re: FRCSim, Gazebo v7, and GearsBot example
I noticed that some of the sensors files need to be renamed.
( e.g., cp libencoder.so libgz_encoder.so )
See lesson learned #4 below.
Watch for errors on startup and create copies of the files as required.
Stick with FRCSIM. I think this will be an important tool once we learn and document how to use it.

==============================================
Limitations:
1) The FRCSIM can take a few tries to start.
2) Joystick methods are not working correctly (getX(), getY() and getZ() )
Use: Robot.oi.joystick1.getRawAxis(0)
// Robot.driveTrainSubSystem.ArcadeDrive(Robot.oi.joy stick1.getY(),Robot.oi.joystick1.getX());
Robot.driveTrainSubSystem.ArcadeDrive(Robot.oi.joy stick1.getRawAxis(0), Robot.oi.joystick1.getRawAxis(1));
Notes: Joystick
- Axis 0 - Left(-) and Right(+)
- Axis 1 - forward (-) and Back (+)
- Axis 2 - Rotate forward (-) and Back (+)
Seems like getX(), getY() and getZ() are not working - wrong order
3) The Analog Gyro does not support the “setSensitivity” method. Comment out in RoboMap.
4) Needed to rename a few sensors (one Time).
