Do you think this could be adapted to smaller robot like this Pi-based XGO CM4[0]

I know they have different hardware but the end result is quite similar: a mobile robot with an articulated grabber. And seeing your prototype made me think of the robot dog.

Smaller robots are unfortunately limited in how much force/torque they can apply and how high they can reach, two factors that we found can severely limit the applicability of a home robot. As a result, unfortunately, we don't have much plans for extending to a smaller robot at this moment.

However, all of our designs are open source! So if you or someone else is interested, it could be a fun weekend project to design a "Stick" equivalent data collection tool for the XGO CM4. I would love to see how that turns out.

Compute on theirs is an Intel Nuc 8 (probably explains a decent part of the price). Appreciate the link to the more "hobbyist friendly" device you mentioned. I am thinking it might do well as a platform for light dusting around the house and other things to supplement a Robovac.

how does a 300-600$ PC explain a decent part of a 20000$ robot?
