Welcome to our laboratory's webpage. This is Keiji Nagatani, associate professor at Tohoku University. Our research topics include field robotics which deals with the fundamentals of robotics in unstructured and dynamic environments. Since Japan has recently experienced an increased frequency in natural disasters the usage of robotic technology is expected to respond to such situations. Therefore, we are now working on the research and development of "practical" field robots that aim to work in disaster-affected areas, such as urban disasters and volcanic environments.
