The answer depends on "before what".
Semi-autonomous space probes have gone to the vicinity of Neptune, but no robots in the popular sense.
No space missions have landed on Neptune or flown by it. The only spacecraft that has visited Neptune is Voyager 2, which conducted a flyby of the planet in 1989. There are no current plans for future missions to Neptune.
Only one spacecraft has visited Neptune: NASA's Voyager 2 probe, which made a flyby of the planet in August 1989. Voyager 2 provided our first close-up images and scientific data of Neptune and its moons.
yes,because there were space-probes and unnamed crafts that found Venus dust-covered and windy
There have been no astronauts that have gone to Neptune. Nor is there any space exploration projects or programs called Neptune that I am aware of.

No the far lest a probe as landed was Saturn
no
yes
Rovers are a type of space probe. Space probes are any robotic mechanism sent out of Earth's atmosphere to explore and gather information.
As of now, there are no manned space probes in space. All probes sent beyond Earth's orbit are unmanned and controlled remotely from Earth. Manned missions have been limited to spacecraft that carry astronauts, such as the International Space Station or missions to the Moon.
As far as we know, no human being has ever been farther from Earth than the moon. All space probes to any other planet have been unmanned. Space probes are automatic and are programmed to send scientific data such as images and readings back to Earth. The human race currently do not have the technology for man to survive long periods of space flight. Space shuttles have enough problems getting into our own orbit, let alone further than our own orbit. It would take years to reach Neptune.

None.
You cant land on a gas giant But probes have gone "inside" gas giants
