Bittle is a robotic dog kit, made by Petoi in collaboration with TinkerGen. Petoi Bittle is a tiny, but powerful robot that can play tricks like real animals. Bittle is an open platform to fuse multiple makers’ gadgets into one organic system. With our customized Arduino board coordinating all instinctive and sophisticated movements, users can clip on various sensors to bring in perception. It is also possible to make Bittle into a full-fledged AI robot by mounting a Raspberry Pi or other AI chips through wired/wireless connections. This makes Bittle a perfect tool for learning, teaching and research!
