Bittle is a palm-sized (200 x 110 x 110 mm, 265-290 g) open-source robot dog from Petoi with 9 servo-driven joints, an Arduino-compatible NyBoard controller, and programming via block coding, Python, or C++. Launched on Kickstarter in 2020 ($567K raised from 2,052 backers), it targets STEM learners ages 10+ and classrooms, sold via Petoi's own store as a construction kit or pre-assembled (all variants out of stock at last check).
Petoi marks the original Bittle 'Final Stock' — it is being discontinued in favor of the Bittle X line. All four kit variants remain purchasable while stock lasts.
Estimated value & depreciation
The Bittle has depreciated beyond what our placeholder model can honestly estimate — a modeled number this small would be a guess, and real units trade on their own market. A real figure appears once actual sales are logged.

US availability & the FCC Covered List
The FCC's rule only covers robots over 4.4 lb once you include the charging dock. This one is under that weight on its own, and we do not have a sourced dock weight, so we cannot say either way.
