Remote operation is the control and operation of a system or equipment from a remote location.
There are several particular types of systems that are often controlled remotely:
Remotely operated vehicles (ROVs) are extensively used in hazardous environments (i.e. radioactive environments, contaminated environments, minefields, deep oceans).
Industrial machinery is often operated remotely, particularly in hazardous environments. One notable example is in the construction of the Object Shelter or sarcophagus at Chernobyl after the Chernobyl accident.
