Temperature at the surface of Venus is hot, 872
F (467 C)! However, many steels and
ceramics are capable of dealing with
temperatures this hot. For example, blades in
modern turbines withstand temperatures of ~2500 F
(~1400 C), thanks to many years of scientific
and engineering and design. It's not just the
temperature though, as there is also a lot of
sulfuric acid in the atmosphere, which is
very corrosive to many metals and ceramics! This
makes things more difficult. In order to build
your rover, you'll have to overcome both the
temperature and acid issues.
The next problem is to do with any devices you
might want to have on your rover, because even if
you can get the materials to withstand the
temperatures and chemicals, you'll need to
think of a way to run any motors and instruments
at 900 F. You'll likely be doing this without
any ventilation, because you wouldn't want to be
pumping corrosive gases through your rover.
Computers we use on Earth are not designed for
these temperatures, and in fact, many of the
treatments for preparing computer chips are around
this temperature, so you'll need to come up with a
clever new way to make suitable computers as well.
