Abstract
A system for supplying energy to a microrobot disposed within a piping system for inspection or repair. The system comprises a microwave transmission section for transmitting as energy a microwave to the robot within the piping system. The microwave transmission section is arranged to transmit the microwave having a frequency equal to or higher than a frequency determined in correspondence with an inner diameter of a pipe of the piping system in which the microrobot is disposed. The microrobot receives the transmitted microwave to convert it into an electric power for operation. This arrangement can ensure a smooth operation of the microrobot within a small-sized pipe because the microrobot is not connected to the transmission section through an electric connection.
