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.

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.
