Check the page Reachy’s computer is not running explaining why you couldn’t have Reachy’s computer on.

  • If the SDK server is running, check Reachy’s cameras from the Python SDK documentation.

  • If not, you will need to have a computer screen plugged to Reachy using an HDMI cable. To view the left camera, in a terminal in Reachy’s computer:

python3 python3 ~/reachy_ws/src/reachy_controllers/examples/view_cam.py left open_cv

You can use the autofocus available in reachy-sdk.

Orbita’s fan is managed automatically based on temperatures limits set for Orbita in Reachy’s software. You can’t control it using Reachy’s SDK.

There might be a problem with the HDMI connection or Reachy’s computer is actually not turned on. You can check the page Reachy’s computer is not running.
