KAIRO 3: A modular reconfigurable robot for search and rescue field missions

Search and rescue field missions, especially in environments which are dangerous for humans, increasingly requires the usage of robust and flexible robots. We describe the development of the modular reconfigurable robot KAIRO 3 focusing on applications in search and rescue, inspection and maintenance. After a short retrospect of previous generations of modular robots, the latest design of KAIRO 3 is presented. In particular, enhancements of the mechatronics and the control software are shown. Furthermore, the necessity to increase the flexibility of search and rescue robots will be demonstrated. To comply with this requirement, we utilized reconfiguration and adaptation of modular robots. Finally, the field results of applying KAIRO 3 at a civil protection field exercise are discussed.
