Thank you for your question. What I did, was connect the RPI to an Arduino via a USB cable. You will have to follow the instructions here: https://www.sunfounder.com/blog/rpi-ard/. It will show you how you can have the RPI communicate with an Arduino via serial communication. So what I did was depending on where the detected object was located, the RPI would send a message to the Arduino to move the servo motors at certain angles in order to pick up the object. I hope this answered you question. Let me know if you need further help.

Hmm... It seems like you don't have the Edge TPU Python API installed. Try running this sudo apt-get install python3-edgetpu
. Let me know if that works.

Thank you for letting me know.

Have you completed this tutorial: https://coral.ai/docs/accelerator/get-started/#on-linux
