Why it’s interesting
Quaddle is an unusually minimal desktop robot dog. Its four legs use only four servos in total, yet the official demonstrations show it walking forward and backward, strafing, and turning in place. Petoi presents it as a kit that can grow from block-based control into Python, C++, and ROS work. Touch reactions, voice interaction, a customizable AI chat persona, and printable shells make the same mechanical frame feel more like a modifiable pet than a fixed classroom model.
How to try it
Begin with the movement, touch, and assembly videos on the official project page. If the four-servo gait is the part you want to explore, review the Kickstarter tier, included components, and delivery estimate before committing. After assembly, run the supplied block-programming examples first, change one gait or expression, and only then move into voice or AI persona features. The advanced paths still require patient building and programming.
Requirements and sources
This is paid hardware that must be assembled, and the launch is a crowdfunding campaign rather than immediate retail stock. Petoi’s page states a September 2, 2026 Kickstarter launch and documents the physical prototype, software paths, and open-source background. Pricing, shipping, taxes, and delivery risk must be checked on the campaign page. The database already contains Petoi Bittle X, but Quaddle is a distinct new four-servo model. The cover remains hosted by Petoi.
