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

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.

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.

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?

Yes, I just purchased your board. I have everything else. The motors are 12v 366rpm and the number on them is: GB37Y3530-30. The encoders came with the motors and are soldered on.

What hardware exactly are you using? Are you using our main board and then using your own motors, batteries etc?

You can just ignore the warning. It just because you have included the USB Host library yourself as well and it comes bundles in the hardware plugin.

You don't have to send me the board, don't worry ;)

Also, I have been getting this error in the arduino ide (its the latest):

WARNING: Category '' in library Servo is not valid. Setting to 'Uncategorized'
Multiple libraries were found for "adk.h"
 Used: C:\Users\stevep\Documents\Arduino\libraries\USB_Host_Shield_Library_2.0
 Not used: C:\Users\stevep\AppData\Local\Arduino15\packages\Balanduino\hardware\avr\1.1.0\libraries\USB_Host_Shield_20

But uploads just fine, seemingly...

By the way, would you like me to send you the older board that I spoke of? My friend seems to have lost his memory on where and when he actually got it. He does swear that he got it on eBay though. But after much research, I kind of think it might be as you said. A cheap Chinese clone. I would be happy to send it to you at my expenses if you would like to have it just because....

Just FYI...

I did that (again) and they are doing the same thing. Could it be the motor encoders that I have?
