I was wondering what is PID loop time?

OK. Scratch that, the above happened once. Now, every time they go in the negative and seemingly do not stop getting smaller.

Stuff hit the fan at work, finally back to normal:
Values started at 0, in a few seconds climbed to 1900 and stayed there. Wheels still spinning opposite.

Questions / Re: Balanduino hardware taking damage from falling?
« Last post by Lauszus on April 15, 2016, 12:24:11 AM »
No the Balanduino hardware will not take damage from simply falling on the floor, as it is protected by the wooden plates which are held together using the threaded rods.

No the long beep can also mean that the Balanduino is not at rest when it calibrates the gyroscope at startup. Please see the following lines in the code: https://github.com/TKJElectronics/Balanduino/blob/master/Firmware/Balanduino/Tools.ino#L446-L462. This is called from the main function here: https://github.com/TKJElectronics/Balanduino/blob/master/Firmware/Balanduino/Balanduino.ino#L268.

The gyro drift you are seeing is likely caused by the calibration routing getting wrong values because the Balanduino is not at rest. I would recommend putting the Balanduino on its side when turning it on.

PS: Sorry for the long delay in my response. I must have missed you post in my inbox.

Software development / Re: LQR/LQG Controller
« Last post by Lauszus on April 14, 2016, 11:23:18 PM »
Currently a LQR controller is not implemented on the Balanduino, but I might be able to help you anyway, as I got a lot of experience in that field.

Hi,

Unfortunately that is not official available, but it is differently possible.

Software development / LQR/LQG Controller
« Last post by univbiskra on April 08, 2016, 12:52:30 PM »
hi

anybody have made a good control for his balance robot by using LQG ?? I am looking for some  advice .

now I finish my robot using LQR but don't seem robust stable ,since the LQR doesn't supporte the noise , for that case I am trying  switch to LQG with states estimator . any body can help.

Getting Started / Autonomous Balanduino

Hi, the Balanduino was out for some time now, has anyone made it to go autonomously with ultrasonic sensors to avoid obstacle?

If Balanduino can do something like this would be awesome.


 

Thanks,
Jimmy

Please add this somewhere in your loop:
Code: [Select]
moveMotor(left, forward, 50);
moveMotor(right, forward, 50);

while (1) {
Serial.print(readLeftEncoder());
Serial.write('\t');
Serial.print(readRightEncoder());
delay(100);
}
And confirm is the values are decreasing or not?
