Robotics: How do we communicate with and manuever a rover on Mars

Robotics: How do we communicate with and manuever a rover on mars?

There are three different DSN antennas that are each 120 degrees around the earth. In order for the rover to be located while moving the DSN antennas recieve transmitions and then detect where the signal is coming from. In order to make sure that there are no problems that occur during very important events such as landing.

Communications

Also because sometimes it is hard to recieve transmitions on earth the rover uses orbiters around mars as a cut-off between earth. The orbiters then relay the transmitions back to earth. 250 megabites would take 20 hours to reach earth. The rover is only in contact with earth for a couple of hours until Mars turns around and loses communication.

The Rover

The outer part of the robot is called the body. It is made of a hard material that is used to protect the computers inside. The computer part of the rove has special memmory that is not affected by the radiation so information won't be lost. Since it is impossible to detect an error in the robot from earth the computers have different ways of detecting the vitals of the rover.

Unlike many of the previous Mars rovers Curiosity does not use solar panels. This was because if there was no/or little sun the rover would be unable to move. Instead Curiosity uses a nuclear reactor powered by plutonium to power it. The plutoniam will at least power the rover for a full Mars year (687 earth days).The rover drives by itself. It uses a program to look at its surroundings and then the best best path to its target.Also to fully keep Curiosity safe the operators on Earth make sure the path is safe before the rover goes on it.
