Overview
A sub-1 kg, stylized AI robot dog that raised $912,768 from 1,150 backers on Kickstarter in 2025. It targets the space between Bittle-class kits and consumer pets, with dance, soccer and trick-learning demos. Hengbot's May 2026 backer update said most reward orders had been dispatched, with about 60 orders to remote countries still clearing customs. As of September 2026 the official site offers only a waitlist, and its store lists no products. In October 2026 Hengbot support said the previous campaign had ended and that Sirius is scheduled to go on sale again in Europe and the United States in November 2026, with the exact launch date and purchasing details to be announced on Hengbot's website and social media.
