Direct DC power supply to the control box

[Tejas-Shastha]

Disclaimer: This is a hardware question, not related to this repo itself. I still write this here since I could not get a response on the official Franka Emika emails IDs. I hope to get some guidance here, or at least to be redirected to a better channel.

I would like to mount an FER1 on a mobile base which is itself DC powered via batteries. Typically the FER/ControlBox requires AC power supply, but most probably converts to DC internally. For us, this could be achieved with DC -> AC conversion from the mobile base's power supply to the control box, followed by AC -> DC inside the control box, but this relatively more lossy and cumbersome. Is there a way to provide DC power supply directly to the control box? Are there any tips on where/how modifications could be done to achieve this? The FER1 is already beyond warranty so that should not be a concern.

Thank you in advance for any support!

Hi @Tejas-Shastha ,
I fear we can't necessarily help you here forward. As far as I know is the power supply somehow an integral part of the hardware and can't just be exchanged. Hence, if you want to make it work, it might only be through the way you already described.

Cheers,
Andreas
