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 `` 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.

pi@raspberrypi:~/adeept_awr $ /usr/bin/python3 /home/pi/adeept_awr/server/
