How can we control robots on mars from earth?

Question

What kind of technology is that? Think about it, you have a remote control car it stops after like a few hundred feet? Mars is like 100,000,000 miles away and we can control a rover there to dig a hole?? Wonder if anyone can explain this to me....

Answer 1

a remote control car uses an antenna, just a piece of metal, to transmit a signal from a tiny computer chip powered by 9v battery.

nasa uses a huge building full of computers to control satellites that send out an electro magnetic signal.

in reality, the only difference if the power of the signal (and the sophistication, but that has nothing to do with how far it travels really).

Answer 2

Mars varies from between something like 5 and 20 easy minutes faraway from the Earth. that's desperate with the help of its orbital residences and it may not in any respect go any larger than approximately 20 minutes. The around-holiday time for this reason varies from 10 to 40 minutes. The cellular rovers which have been despatched to Mars have some quantity of self sustaining ability. it extremely is to assert, controllers in the worldwide are able to deliver a message like 'flow foward 2 meters' and the rover will instantly make certain no be counted if it needs to alter its direction around rocks or despite it may come across whilst utilizing. moreover, they flow truly slowly. The MERs have been utilizing at an standard of something like a meter consistent with day, consistent with possibility much less. Over the direction of day, controllers get a minimum of 36 around-holiday situations (24 hours divided with the help of 40 minutes is 36), so they even have time to regulate the rovers' motions with a great deal of precision. As for the photographs, those are despatched back with the help of potential of radio indicators basically like each the different information the probes deliver. For the MERs specifically, I remember that the susceptible sign from the rover is truthfully picked up with the help of an orbiting spacecraft, which then sends a a lot extra effective reproduction of that sign back in direction of the Earth.

Answer 3

The rovers are much smarter than your remote control car. They don´t need radio signals for every little maneuver. Their computers do the work. All controllers need to do is to give the rover an assignment. "Go sniff that rock". And then the rover figures out the route to go and controls its steering on its own. As it gets to the rock it deploys its rock sniffer, does its business and sends the data to earth. All autonomously. You can actually buy your own autonomous robot kit in a hobby or electronics store. You should try it when you are bored with your little toy car.

Answer 4

the rovers are given command to move a very short distance at a time. then NASA waits for a new photo to arrive showing the new view of the terrain. then after much discussion, a new command is sent to move the rover another short distance, It is a slow painstaking process.

for terrain that is not too rough, the rovers have sensors that recognize a large boulder, for example, as a 'disruption' in the visual field and which will automatically steer the rover away from the boulder. But for anything delicate like climbing hills and descending into craters, it's slow and meticulous work.

Answer 5

Simple, you tell it what to do and transmit that data to Mars.

Since the rovers can't go very fast (less than walking speed) it only moves a small amount every day. We get the terrain data from the cameras and use that data to tell the robot where to drive the next day. The on board computer stores that data and uses it when its needed. Also, the on board computer is capable of doing some autonomous decision making.

Answer 6

a remote controlled car's contorller works off of a 9 v battery.

Nasa doesn't use 9 v batteries

Answer 7

We cannot control robot on mars and do you even know if there are any robots on mars!!!!
