Hello from Team 11999!

[jvanetten]

Hello everyone.

We are a rookie team this year. I was wondering if we could get a hand with a question that has been a problem for a couple of weeks. Right now, our robot has a program that loads onto the driver station and seems to work (we can see the telemetry working for the remote and everything), but our robot does not move. I was wondering if anyone else has had this problem? Is it a problem with our code or is it a connectivity issue with the phone and the controller?

Thanks for helping out!

Could you post your code?

public class AtlasTeleop extends LinearOpMode {


HardwareAtlas robot = new HardwareAtlas();

double clawOffset = 0;

Since you are using LinearOpMode, you need a create and call an waitForTick method in your loop.

/***
*
* waitForTick implements a periodic delay. However, this acts like a metronome with a regular
* periodic tick. This is used to compensate for varying processing times for each cycle.
* The function looks at the elapsed cycle time, and sleeps for the remaining time interval.
*
* @param periodMs Length of wait cycle in mSec.
*/
public void waitForTick(long periodMs) {

long remaining = periodMs - (long)period.milliseconds();

// sleep for the remaining portion of the regular cycle period.
if (remaining > 0) {
try {
Thread.sleep(remaining);
} catch (InterruptedException e) {
Thread.currentThread().interrupt();
}
}

// Reset the cycle clock for the next pass.
period.reset();
}

Awesome! Thank you.

I got so confused for a second because I was in FRC thinking mode and was like, 11999????? WAY too many numbers there! And then I stopped to think, and yah. I haven't slept very much lately.

Yeah we are FTC, and this is my first year in the robotics world. So far it has been exciting and fun.
