The robot page is arguably the most important page in the Dashboard. It provides information across several tabs, accessible in the top navigation bar.

The robot page has several tabs, each accessible from the top navigation bar.

Info

...

The “Info” tab shows high-level robot diagnostics, including static information, live data, and status information.

Static information:

  • hostname: the name of your robot

  • Robot type: there are many kinds of robots in the Duckietown ecosystem; Duckiedrone is one type.

  • Configuration: there are several “editions” of each robot type. The latest Duckiedrone is DD21.

  • Firmware: software version installed on your Duckiedrone.

  • Board: Raspberry Pi or Jetson Nano (should be Raspberry Pi)

  • Model: Board version.


Live data:

  • Temperature: current Raspberry Pi temperature. It should never go over 80C. Start getting worried around 75C. Excessive temperature will trigger Throttling (see below).

  • Disk: available hard disk space (default capacity is 32GB);

  • CPU: current processor load;

  • RAM: current temporary memory load;

  • Frequency: CPU clock (maximum is 1.4GHz for Raspberry Pi 3B+)

  • Battery: this feature is currently only available for Duckiebots (DB21).


Status Information:

And history and current status information (green status represents healthy condition):

  • Under-voltage: green represents healthy status. This warning will trigger when the input voltage to the Raspberry Pi is too low. Make sure your UBEC is properly installed if you are getting this warning.

  • Frequency-capped: this status implies the computation capability of the Raspberry Pi is limited, e.g. because of high temperature.

  • Throttling: this warning will turn on when the Raspberry Pi is limiting its cycles due to unsuitable voltage conditions.

Finally, in the top right corner “Power” icon, you will find a convenient way to soft-shutdown (or reboot) the Raspberry Pi.

Troubleshooting

Problem: The power button does not generate the intended outcome.

Solution: The power button currently only works through the Info page of the Dashboard. If you find it unresponsive on other pages, just navigate back to Robot > Info.
