A probe buit to land on Mars is built with considerable "Artificial Intelligence" in its onboard software, so that it doesn't need control from earth for every move ... it's capable of some autonomy, i.e. making some of its own decisions as it goes about its business. In order to control it when necessary ... and also to get ahold of the probe's reports, data, pictures etc. ... comunication is by radio. The peculiar thing about it is that the radio signals take more than a minute to travel between the controller on earth and the probe on Mars; so if the timing of a command is critical, the command has to be sent more than a minute before the probe needs it, and for the same reason, the result can't be known until almost three minutes later.
the two rovers are:- Spirit and Opportunity.
As of 2021, there are several active Mars rovers, such as Perseverance and Curiosity. In addition to Mars rovers, there are other robotic rovers deployed on celestial bodies like the Moon and other planets. The exact number of rovers in operation worldwide varies as missions launch and conclude.
So far, Nasa has successfully acquired four Mars rovers: the Mars Pathfinder, Sojourner, Opportunity, and the Spirit. These were managed by the Jet Propulsion Laboratory and the Mars Science Laboratory.
A Mars rover is a robotic spacecraft that explores the surface of Mars. It is equipped with cameras, sensors, and various scientific instruments to study the geology, atmosphere, and climate of Mars. Rovers are controlled remotely from Earth and help scientists gather valuable data about the red planet.

No one has sent 15 rovers to Mars
Mars rovers were made sometime in the 1970's
All of their Mars Rovers have wheels.

They are taken there, by spacecraft.

No. But rovers have.
yes, the mars rover
As of November 2016 there are two operational Mars rovers: Opportunity and Curiosity.
There have been seven attempts at sending rovers to Mars of which four landed successfully.
