4 years ago Dear @ckeown , from the error message I would guess it is a problem with the pybullet version you are using.
Are you running real-robots-demo in an Anaconda virtual environment? If you create the virtual environment as suggested here (using this yml file) it should work.
The suggested pybullet version is: 2.5.3
What I Did
I tried running real-robots-demo at the terminal, as well as the python code in the readme, but I seem to get the same error. See below. I tested it directly, and the important seems to execute fine. Any thoughts? Thanks!
Output
