CASSANDRA - heterogeneous reconnaissance robotic system for dangerous environments

Robotic system consisting of multiple different remotely operated robots and one operator´s station is described. The system consists of two small robots, two bigger robots, and one flying machine, while each of them has different features to form balanced system for variety of missions. The robots, as well as the whole system and its possible mission configurations are described in the article. Great attention is paid to the communication subsystem, i.e. not only robot-to-operator´s station communication, but also signal retranslation.
