[Errno 121] Remote I/O error

Quick question: Can you test serverTest.py with just the raspberryPi? Or did you need the rasptank fully assembled when you're testing for the first time? What is serverTest.py supposed to do? Check if the servos are working properly?

This is the output I got when I tried to test it:

pi@raspberrypi:~/Adeept_RaspTank $ sudo python3 server/serverTest.py
