Overview

The best small robot that really balances and also has a full Linux computer for Python, vision and a voice assistant. The legs are simple (one servo per side driving a linkage), so it's a height- and tilt-adjustable balancer, not a walker. Same maker and software lineage as the XGO dogs in the Quadrupeds section.

Best "balances today, under $500, programmable in Python" option.
