Editor's notes
Unverified (free text): open_source hardware. Dimensions 200x110x110 mm. Weight 265–290 g is given for the Bittle STEM kit on the overview page, not specifically for Bittle X, so mass is left out. Payload "up to 1 lb" recorded as 0.45 kg. The product page quotes a safe speed "about 40 mm/s (2 body lengths per second)", which is internally inconsistent, so max_speed is omitted. Manufacturer markets it as open source (OpenCat ESP32 on GitHub); hardware licence not verified. Petoi also lists "Bittle Robot Dog (Final Stock)" — the original Bittle seems to be being phased out in favour of Bittle X.
