Yes.
Some space probes have small robots called "rovers" that are designed to explore the surface of planets or moons. These rovers are equipped with various instruments and cameras to collect data and images.
Semi-autonomous space probes have gone to the vicinity of Neptune, but no robots in the popular sense.
There have been two space probes: Mariner 10 and Messenger.
Some of the "Venera" space probes succeeded in landing on Venus. The first was in 1970.

No. Space probes have orbited and flown by Saturn, but nothing can land there. Saturn is a gas planet, and therefore does not have a definite surface.
Yes, several robots have been sent to Saturn. They are usually called "space craft" or "probes."
Space probes would be safer.
How do space probes aid in space exploration
Probes in Space was created in 1975.
As of June 2021, there are several robots in space operated by various space agencies and companies for tasks such as maintenance, exploration, and research. A specific number is difficult to provide as new missions are constantly being launched and existing ones decommissioned.
Because humans aren't allowed there, but robots are fine. (There's a sign that says so, which is why they're so interested in going.)
