• powering sbc: https://synthiam.com/Support/Tips-to-Make-a-Robot/Powering-SBC-(Single-Board-Computer)

and there are a few other useful documents in that support group.

Below is some information that might help you out:

For powering your SBC, many users have found success with both 12V battery packs and LiPo/Li-ion batteries. A common approach is to use a 12V battery in combination with a voltage regulator or buck converter to provide 5V (or whatever voltage your SBC requires). This setup offers flexibility and efficiency for mobile robots. You can check out our detailed notes on powering an SBC here:
Powering SBC (Single-Board-Computer)

When it comes to remote connectivity, a headless setup has become a popular solution. Tools like TightVNC allow you to control your SBC remotely from a PC, tablet, or even a laptop. Some users have experimented with using tablets as an SBC interface by running a remote desktop or VNC client to monitor and control the system. The decision really depends on your project requirements, mobility needs, and the available hardware. Our support document on headless SBC configurations might be valuable as well:

In many cases, users opt for a standard PC or notebook when value, processing power, and connectivity are priorities. That said, if portability is critical, a tablet paired with a remote desktop client can work quite nicely as well.

What do you currently have in your setup? Are you looking for a more compact, field-ready solution, or is desktop accessibility more of a priority? Let me know if you need more details on any of these options, or if there are any particular challenges you’re trying to overcome, and I’d be happy to help further!

Thank you for summarizing the solutions used by users. I had read the correct information and documents provided by Synthiam, and I was wondering what users were using.

Might be easier to assist if we have some background informations about your robot.

Me personally, currently using a intel n100 mini PC with 16gb ram as an onboard computer. For power I went overboard and purchased a bluetti AC2A. Yes overkill, but wanted room to experiment and grow.

For remote into the computer  Synthiam remote access, sometime my phone with the ARC app. Tightvnvc mostly. And chrome remote desktop.

Chrome remote desktop is mostly a back up for my back up.

Day to day thightvnc.  I am also running tailscale VPN, so can always VPN into my home network and use tightvnvc.

@PJ_Dtechy  thx for sharing.  Right now, I'm using a three-wheeled robot, not very big. I'm still thinking about modifying the design, maybe into a telepresence robot. For this project, the AC3A is too heavy, but it's interesting to see what users are using. I have another project coming up, similar to InMoov, so the AC3A could be a solution for that, for example.
