This is the code that i made but i dont know if it works and i cant test it out because i dont have a robot.

task main()
{
while (true)
{
if (vexRT[Btn6U]) //i am using the channel 6 button U to lift the arm up
{
motor [armmotor left] = 40; //this motor will be reflected in motor and sensors set up
motor [armmotor right] = 40;
}
else if (vexRT[Btn6D]) // i am using channel 6 button D to bring the arm down
{
armmotor right Reflected // i am not sure if this code "armmotorright Reflected" will work
motor [armmotor left] = 40;
motor [armmotor right] = 40;
}
else
{
motor [armmotor left] = 0;
motor [armmotor right] = 0;
}
}
}

Yes, this looks like it will work. I don't know bout how your motors are arranged, so you may have to put a negative sign on one of the numbers, or reflect the correct motor. Speaking of which, the way you reflect the motor is by typing "bMotorReflected[armmotorleft]". This should usually not be done in the while loop. Instead, put it at the top of your program after task main(). If you need to change the direction of motion, put a negative sign in front of the value.
