[SOLVED] Browser Streaming Robot problems


#1

Hi,
We bought the GoPiGo some months ago. We have tried most of the projects succesfuly, but now we’re having problems to make the Browser Streaming Robot work. At the beginning it worked well, but since last days of August we’re getting this error:

pi@raspberrypi ~ cd Desktop/GoPiGo/Software/Python/Examples/Browser\ Streaming\ Robot/ pi@raspberrypi ~/Desktop/GoPiGo/Software/Python/Examples/Browser Streaming Robot sudo chmod +x robot_web_server.py
pi@raspberrypi ~/Desktop/GoPiGo/Software/Python/Examples/Browser Streaming Robot
$ sudo ./robot_web_server.py
sockjs.tornado will use json module

We’ve tested in different networks and we always get the same error. We have tested the camera with the raspistill -v -o test.jpg
command and it works properly so we think it is not a camera issue.

Looking for your help,
Franco

Hey,
Looks like a bug got into the code-base when we were cleaning it the last time. We just cleaned it up and there was a just an error in the file-path to a HTML file: https://github.com/DexterInd/GoPiGo/blob/master/Software/Python/Examples/Browser%20Streaming%20Robot/robot_web_server.py#L92.

You should do a pull for the git repo and try again.

Do let us know if this helps.

Hi Karan,
We’ve done what you have told us and now we can control the robot but we have no image, we get the following error:
pi@raspberrypi ~ cd Desktop/GoPiGo/Software/Python/Examples/Browser\ Streaming\ Robot/ pi@raspberrypi ~/Desktop/GoPiGo/Software/Python/Examples/Browser Streaming Robot sudo chmod +x robot_web_server.py

Hi again,
The camera works fine, we were not connecting it to the correct port :stuck_out_tongue:
Thanks for your help Karan!
