Going forward with the integration of my GopiGo2/Pi3B+ Raspbian for Robots OS with Google Cloud API, I’m experiencing some issues that I want to share with forum in order to understand if somebody else has already figure out a solution.
First, when I coding having pi3b+ powered via usb no issue at all. Power stability is ok, but commands that I send to the motors and servo don’t have the same effect. For understanding, running the command left() with time.sleep(0.5) generate a longer rotation when GopiGo is on battery rather then when is plugged on the Pi board. Of course there is a difference of voltage between energy provided by usb and battery through gopigo card, my question is if you all you guy have fixed it only via coding or by plugging a power supply through gopigo card…
Second, and this is a real problem, for some reason and I don’t know why after 10 minutes on battery the system becomes to be not stable and by connecting a monitor on hdmi board I see that raspberry is keeping rebooting itself.
At that point I have turned off the system. I have restarted but after a minute became unstable again. I guess some hardware issue may be involved.
After 15 minutes I have tried again and now the system seemed to be stable back on battery. The voltage measured was 8.7V.
Any idea? (thx)
