Naver Labs, the research subsidiary of South Korean search giant Naver, has opened the patent and design for its robotic cart, dubbed AIRCART, the company announced. Third-party developers will be able to use an open kit provided by the firm sometime within the first half of next year to create related robotic products, the company said. The kit will have the source code, circuit design board, and user guide for the patents. AIRCART is an electronic cart with physical human-robot interaction technology applied that augments strength. A strength sensor on the handle reads the user's intention and controls power and direction, and the user can then move heavy items with little exertion.
