Adeept AWR 4wd Robot:OSError: [Errno 121] Remote I/O error

1619899089

Hi

I have purchased the Adeept AWR 4wd Robot. I find the documentation pretty good. I followed the documentation. I have assembled the robot accordingly, but i still get this issue described below.

my issue might be here: However, if the Raspberry Pi camera or Motor HAT is not connected, the `webServer.py` can't run well.It makes sense because the robot's program needs the camera and the chipset PCA9685. Motor HAT controlsservo with PCA9685; the Raspberry Pi communicates with PCA9685 via I2C; so if Motor HAT is not connected toRaspberry Pi, a program error will occur when instantiating dependent libraries for PCA9685 due tocommunication failure. But I have assembled the robot full.

I am getting the following the following error attached in the screenshot. just to be sure I am also pasting the error code to the thread. I have assembled the robot full and i have enabled the I2C. It would be great if some one can help me here.

Hello 1619899089, could you solve the problem? I'm facing the same issue. Best Regards Goepp

Please check if the I2C address is normal.
Enter in the Raspberry Pi: i2cdetect -y 1
In general, addresses such as "40, 70" can be seen in the result of the instruction running. (The leftmost 00~70 are not counted)
If "40, 70" is not displayed, it may be because the HAT is not installed correctly, or the HAT is faulty.

Hello.
I checked the I2C addresses and instead of "40,70" I got "48,5f,70"
Does this mean that my Motor HAT is broken or is there anything I can do to fix the problem?
