3D printed a lil robot to monitor my cats while I'm away. Based on the watney rover design by nikivanov. I made a handful of modifications so the rover could fit the google AIT voice hat.

Also designed and printed some omni-wheels for the rover so it wouldn't get jammed in the carpet. https://www.thingiverse.com/thing:6493536
It never made it into regular use cause of bad connectivity issues. Got a new USB wifi card for it which should fix it but haven't gotten around to adding it yet.
