Thank you for your help. Here’s what I have as the output of the three commands:
pi@raspberrypi ~ $ sudo i2cdetect -y 1

ATTENTION! Important!
BEFORE PROGRAMMING THE GOPIGO FIRMWARE, DISCONNECT THE MOTORS.
Please confirm that you’ve disconnected the motors.
Have you disconnected the motors before programming the firmware? (y/n)
