2021: The first-generation robot dog B1

This was our first robot dog version, built with LEGO blocks. We open-sourced its gait node algorithms—the same gait style later seen in many imitations.

2022: The second-generation robot dog B2

This was our first fully autonomous robot dog, already able to perform all kinds of demos on a desk.

2023: The third-generation robot dog B3

In this version we introduced Chinese kung fu concepts and designed a structure that is symmetrical front-to-back and top-to-bottom.

2024: The fourth-generation robot dog B4KT2

This is B4KT2, the fourth-generation robot dog designed for the Kickstarter project.
