Welcome to "Intelligent Systems Laboratory" (NAGAI Lab) ! (Japanese page is here)
We belong to Dept. of Mechanical Engineering and Intelligent Systems, Graduate School of Informatics and Engineering, The University of Electro-Communications.

We are interested in various intelligent systems including humanoid robots

Our group is working on the development of intelligent systems that can recognize their surrounding environments, communicate with people naturally, learn (adapt) and think. We believe that these systems help and enrich our everyday life.

Team Kara@ge++ (RoboCup@Home project)

In our group, a project team called "team Kara@ge++" is formed to participate in the RoboCup @Home league. The team develops a humanoid robot platform "DiGORO". The team is also involved in many activites like demonstrations of the robot at exhibitions.
