Single Joystick Problem

D1581A · Tue Dec 14, 2010 4:58 pm

So we are basing our user control code off of the single joystick sample program supplied with robotc for our VeX cortex robot. However, we have modified it so that it runs off of two joysticks: (similar to an xbox controller) with steering on the right joystick, and moving forwards/backwards on the left joystick.

Our issue is that with our current code, the right joystick (steering) is reversed. For instance when you push the stick to the right, the robot will turn left and vice-versa. I'm hoping that it's just a simple program fix, and i'm thanking you in advance for your answers.

Supplied below is our user code as it is now.


	Code: #pragma config(Sensor, dgtl1, rightencoder, sensorQuadEncoder) #pragma config(Sensor, dgtl3, leftencoder, sensorQuadEncoder) #pragma config(Motor, port2, rightMotor, tmotorNormal, openLoop) #pragma config(Motor, port3, leftMotor, tmotorNormal, openLoop, reversed) #pragma config(Motor, port4, rightarmMotor, tmotorNormal, openLoop) #pragma config(Motor, port5, leftarmMotor, tmotorNormal, openLoop, reversed) #pragma config(Motor, port6, rightclampMotor, tmotorNormal, openLoop, reversed) #pragma config(Motor, port7, leftclampMotor, tmotorNormal, openLoop) #pragma platform(VEX) task main() { while (true) { //Wheel Motors motor[leftMotor] = (vexRT[Ch3] + vexRT[Ch1]); //y-axis value: forward/backward motion motor[rightMotor] = (vexRT[Ch3] - vexRT[Ch1]); //x-axis value: left/right steering //Arm Motors motor[leftarmMotor] = -vexRT[Ch3Xmtr2]; motor[rightarmMotor] = -vexRT[Ch3Xmtr2]; //Clamp Joystick motor[leftclampMotor] = -vexRT[Ch2Xmtr2]; motor[rightclampMotor] = -vexRT[Ch2Xmtr2]; //Clamp Joystick- } }

Thanks again
