Multi-touch Interface for Controlling Multiple Mobile Robots Abstract We must give some form of a command to robots in order to have the robots do a complex task. An initial instruction is required even if they do their tasks autonomously. We therefore need interfaces for the operation and teaching of robots. Natural languages, joysticks, and other pointing devices are currently used for this purpose. These interfaces, however, have difficulty in operating multiple robots simultaneously. We developed a multi-touch interface with a top-down view from a ceiling camera for controlling multiple mobile robots. The user specifies a vector field followed by all robots on the view. This paper describes the user interface and its implementation, and future work of the project.

users. We therefore need interfaces for giving instructions to them. Single robots are normally controlled with joysticks, keyboards, and other pointing devices. However, with advances in robotics, variations of user interfaces for these purposes have become wider. For example, multimodal interfaces such as combination of hand gestures and speech for one assistant robot [1], and a portable interface using personal digital assistant (PDA) for mobile robots [2] have been proposed. This system allows users to navigate a robot with waypoints projected on the screen. Recently, user studies of intuitive interfaces [3] have been performed, in which motor impaired users have a robot grab things with laser pointers and a touch-screen with buttons on it. Among these studies, it has been concluded that the invention of advanced user interfaces helps operating single robots. Handling tasks with multiple robots is also desirable,
