We fine-tuned every bit to fit agile maneuverability into a palm-sized robot pet. You can bring Bittle to life by assembling its puzzle-like frame and downloading our demo codes on GitHub. You can also teach it new skills to win prizes in our community challenges. Bittle makes a perfect tool for learning, teaching, researching, or a surprising gift to impress your family and friends. Bittle is not a toy for small kids. We recommend parental guidance to appreciate its rich content and avoid damage or injury. - Evolving with an open-source gene, 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, you can clip on various sensors to bring in perception. You could also inject artificial intelligence capabilities by mounting a Raspberry Pi or other AI chips through wired/wireless connections. - Bittle is a palm-sized robot that moves with four legs rather than wheels. Legged motion gives it more freedom to navigate unstructured terrains, and expresses the joy of life whenever it moves. Such dynamic maneuverability was only seen on a few luxury robots from the best labs or tycoon companies previously, such as Boston Dynamics Spot or Sony Aibo. We came up with a grassroots solution to simplify the system to make it affordable and mass-producible. - Bittle is a compact system of five major components: body frame, actuator, electronics, battery, and the software to coordinate all the hardware to perform varied tasks. - We designed Bittle's interlocking frame as a 3D puzzle with very few screws involved. Most body parts are symmetric for simplicity and aesthetics. - It's a pleasure to assemble and disassemble Bittle for teaching or maintenance. On average, it takes about one hour to put together the body from scratch. - Each piece has gone through tens of iterations with 3D printing. We then use high strength injection-molded plastic to provide the best protection from collision and dust (it's NOT waterproof!). In the stress tests, the assembled robot can take an adult's stepping without breaking any components (do NOT try this at home!). - We also designed Bittle to be soft. Besides the elasticity of the material, the spring-loaded upper legs flatten the shock on joint servos to protect their gears. Bittle usually survives regular collisions. In the extreme cases, it will disintegrate at the designated "weak link in the chain", which is easy and cheap to reinstall or replace. - We designed the frame to be compatible with most 9g servos. You could order the "Bittle Shell" perk alone to compile your spare servos into a beautiful action figure! - We visited several servo manufacturers and iterated many times to find the optimized parameters. It will be model P1S, a slim, fast servo with a controllable angle of 270 degrees. - We use nine P1S servos to actuate Bittle. Eight of them are for walking joints, and one is for head panning. We will also include one spare servo for replacement, as brushed motors are consumable after a certain period of wearing. You may order the "Bittle Servo Set" perk if you expect to use Bittle intensively for teaching or researching. - Bittle is driven by NyBoard V1, a customized Arduino board with rich peripherals. We fully utilized the chip of a regular Arduino Uno to coordinate sophisticated motions. The board can drive at least 12 PWM servos, and an IMU (Inertial Measurement Unit) is used for balancing. It stores "muscle memory" and detects body status (orientation and acceleration) for balancing. We provide an infrared remote to trigger basic movements. The board also listens to string commands from the serial port, such as "walk", "sit", or more detailed instructions for individual joints.
