Development of an immersive teleoperating system for unmanned helicopter [PDF]
Proceedings. 11th IEEE International Workshop on Robot and Human Interactive Communication, 2003 To collect the information on devastated districts, it is effective to use helicopters. However, the operation using manned helicopters costs a lot. It is expected that the use of unmanned helicopters can reduce the cost of these tasks. It is known to be more difficult to operate unmanned helicopters remotely than to operate manned helicopters.
