We are a Boston-based startup with the goal to make robots fully taskable by non-experts instead of having to program them. We provide a comprehensive software infrastructure that allows users to instruct robots through natural language dialogues and graphical user interfaces. When robots do not have sufficient knowledge for carrying out an instructed task, they will let users know. Users can then teach the robot any missing knowledge, for example, by describing objects or by demonstrating actions. The ability to interact with users in natural ways and to learn quickly from these interactions provides the basis for robots to operate in “open worlds” and adapt to unexpected changes as needed.
