This paper describes a method for Event handling on Robot Town platform and its application by using a wheelchair robot. To enable a sharable personal mobility robot system by using a motorized wheelchair on the market, vision sensors and RFID tags are distributed and are connected to a network. Sensor data are used by the robot for not only the event to perform self-localization but also the event...
This paper describes a platform of ambient intelligence for robots working in an ordinary environment for daily human life. To enable autonomous robotic activities, vision sensors and RFID tags are distributed in the environment and are connected to a network. The data from distributed sensors are integrated, and are provided to robots to support their activities. Based on the analysis of sensor functions...
This paper proposes a calibration method of a distributed vision network in a unified world coordinate system. The vision network system is conceived to support a robot working in our daily human life environment: the system provides with visual observation of the dynamically changing situation surrounding the robot. Vision cameras are rather sparsely distributed to cover a wide area such as a block...
We propose a new framework and novel visual control system for motile cells in three-dimensional (3-D) space. Our goal is to utilize microorganisms as micro-robots in various applications by exploiting galvanotaxis (locomotor response to electrical stimulus) to actuate them. This requires automated motion control of swimming cells in 3-D space; in contrast, our previous work has been limited to 1-D...
This paper describes a new approach to an intelligent robot working within an ordinary environment for daily human life. To enable autonomous robotic activities in such environment, vision sensors and RFID tags are distributed in the environment and are connected to a network. The real-time data from sensors and robots are integrated by a management system together with GIS and other database. Being...
This paper proposes a new approach to structuring a free space model in tele-robotic environment by using a slave manipulator equipped with a stereo vision tele-operated by a human operator. Using initial tele-operated motion data of the manipulator, structure of the empty space is reliably and conservatively obtained without explicit geometric model of objects in the environment. A post-processing...
