Oberon is a moon/satellite of the planet Uranus.
A satellite is a Space Robot?
No: modern space travell has not yet advanced sufficiently to send a probe into Uranus. It is too far away. However, we have managed to take some nice photos of it.
The name of the spacecraft that visited Uranus is Voyager 2. It flew by Uranus in 1986, taking detailed observations of the planet and its moons.
There is no way to colonize Uranus. Because astronauts have not even been there. They can only get satellite pictures.
what satellite or robot explored Saturn
1 has been sent to Uranus. That was the "Voyager 2" spacecraft. Strictly speaking, it wasn't a "satellite" because it did not go into orbit around Uranus.
Uranus has 24 known natural satellites.
