1. Humanoid Robots

We aim to realize a humanoid robot with enhanced stability and reliability that can perform complex tasks in cooperation with humans in our daily life. Leveraging the latest results in biology and brain research, we investigate the performance of bio-inspired mechanisms and neural control methods. We also develop an epigenetic based approach to building a developmental architecture for generating robot personalities and helping reduce human-robot interaction gaps.

2. Human-Robot Interaction

Establishing multi-modal interaction channels necessary to understand human intention, we build various types of user-intention driven assistive systems in support of society. Examples include an active robotic walker supporting ambulatory capabilities and a power assist cart helping a user easily transport objects in various weights.

3. Networked Robots

In order to realize an idea of human-robot symbiosis in our everyday environments such as a home or office, we construct an information-rich infrastructure that shares information processing functions with mobile robots using a data carrier. We develop distributed control methods that enable sophisticated manipulation tasks through integrating distributed knowledge of individual objects. Different types of direction sensing RFID systems are developed and applied to rapid data acquisition and autonomous indoor navigation, helping mobile robots make decisions on the fly.

4. Autonomous Mobile Robots

We develop simultaneous localization and map building algorithms for autonomous wheeled and unmanned aerial vehicles exploring unknown environments. In order to facilitate the recognition of surrounding environments, we design and manufacture a series of small, lightweight three-dimensional range sensor positioners equipped with a single motor. We also investigate the collective and emergent behavior of robotic swarms that appears through local interactions among individual robots, and flocking algorithms that control swarm formations adapting to any environmental changes.

5. Perceptual Learning

We develop computational neural models of active depth perception based on smooth eye pursuit and motion parallax toward implementing self-calibrating artificial vision systems. In addition to demonstrating the effectiveness of the efficient coding hypothesis, we conduct neurophysiological and biological elucidation of engineering models designed to implement developmental learning theories of active perception on a humanoid robot.

Teaching policy

Within the framework of research projects aiming at improving the robotics technology and its real world applications, students explore different topics and are responsible for conducting themselves in achieving their goals. Multi-faceted and flexible viewpoints and innovative thoughts are cultivated through communications with other members and teamwork and collaboration. Students are encouraged to utilize the software and hardware resources available in the laboratory and enjoy implementing half-baked ideas and new concepts. Seminars and progress report meetings are held periodically. Occasionally, we also hold project team meetings. Overall, students conduct research on their own initiative under flextime in an atmosphere of freedom.
