QuadTrack-II: A Remotely Operated Mobile Robot with Four Articulated Tracks

This paper introduces a remotely operated robotic system being developed for urban search and rescue. QuadTrack-II has four modular track arms which can be driven independently to get a traction force. The modular track arms can also be rotated with respect to their arm axes to lift the body or step over larger obstacles. It has some observation module for gathering information of disaster areas. Inside main body frame, it can carry a small serial multi-linked mobile robot to collapsed areas to find human victims under the rubbles. This paper describes the structures of the robot and some advantages of mobile robotic system with articulated modular tracks and shows some experimental result for various environments.
