An important function of a robot is to acquire three-dimensional (3D) distance information. Using 3D distance information, a robot can grasp the surrounding topography and obstacles. In a joint effort with Nippon Signal, the Future Robotics Technology Center is developing 3D laser range finders, which are sensors of the 3D distance information. Research and development is under way for a personal mobility system featuring such a sensor – an electric wheelchair with increased safety. And here at this spot, a 3D laser range finder is used in the visitor counting system. This is an example of what a robot eye can do.
