alternative software installation method

[Andy Sun]

Hi everyone, I'm currently trying to build a pupper following the document, however things didn't work well for the software. There were a lot of unexpected errors and issues come out with raspbian. For example I can't even boot the pi normally even with the 2020 version of raspbian. Therefore I wanna know if there is a newer version of raspbian and RPI repository such that the software can run well in pi 4b?

Thanks,

Andy

Hi Andy, sorry you have so many issues. My suggestion is to install the latest Raspbian (https://www.raspberrypi.com/software/) to ensure that the Pi actually boots, and then manually install the prerequisite software instead of relying on our image. I suspect that our image is just too out of date for it to work anymore. 

Here's roughly the steps you should follow to reach equivalent functionality as our image:

* Connect to WiFi (you will probably have to connect your Pi to a monitor and keyboard)

* Enable SSH

* Install pip

* Install UDPComms (https://github.com/stanfordroboticsclub/RPI-Setup/blob/7aa9d60ab173a085cbc52e6d2adec6086109a2ff/appliance/home/pi/install_packages.sh#L47C1-L49C30)

(For more information, see https://github.com/stanfordroboticsclub/RPI-Setup/blob/master/appliance/home/pi/install_packages.sh which is the install script referenced by https://pupper.readthedocs.io/en/latest/guide/software_installation.html#install-prerequisites)

After that you should be able to start the setup guide from https://pupper.readthedocs.io/en/latest/guide/software_installation.html#installing-the-stanfordquadruped-software-on-the-raspberry-pi

Let me know if that works and I'll update the guide! Thanks!

Hi Nathan,

I just finished calibrate the feets anyway but when I try to use the controller it gives no respond, the servos move normally when calibrating, may I know what might goes wrong？

Something is probably wrong with the joystick service. Did you run this script? https://pupper.readthedocs.io/en/latest/guide/software_installation.html#install-requirements-on-the-pi https://github.com/stanfordroboticsclub/StanfordQuadruped/blob/master/install.sh . You should also try running the joystick script joystick.py which is inside PupperCommand https://github.com/stanfordroboticsclub/PupperCommand/blob/master/joystick.py. When you turn on the controller you also have to pair it (every time).
