This paper discusses two unconventional and complementary systems for sensor movement. The first platform is the Dervish, originally designed to bypass the problem of mine detection by deliberately rolling over them with mine-resistant wheels. The second uses carbon-fibre cables to set the position of a payload supported by a balloon. Some desirable features of a sensor platform might be as follows.
