because the are controled by a pc know as a computer
yes they move
No, robots do not have to move to be considered a robot. Movement is just one characteristic of robots, but they can still be classified as robots based on their ability to perform tasks autonomously or semi-autonomously, even if they are stationary.
Yes they can.
Robots can move using various mechanisms, including wheels, tracks, legs, and propellers. These mechanisms are powered by motors or other actuators that provide the necessary force and motion for the robot to navigate its environment. Additionally, some robots can also move by crawling, hopping, or flying, depending on their design and intended tasks.

The traditional view of robots as semi-intelligent machines that can move around and behave like humans is a long way from the norm. Although there are robots that are human like, the vast majority are industrial robots. They are built and programmed to do very specific jobs such as product assembly, picking and sorting. These industrial robots are normally firmly fixed into one place and have no chance of moving anywhere.
Yes, they do, With the wheels under them is what makes them move. Depending on the type of robot your are distrubuting or making.
It depends on what you are trying to do with robots. If you are trying to get into robotics (the subject of this category), then I would not get started with the robots or parts from the shop you mention. I would start with one of the Lego kits that include NXT brain. You can then gradually move to more complex robots. I would also look at usfirst.org to see if you can get involved there.
To demostrate how modern robots can move around without loosing balance
The only way robots would be helpful to us as a human race, would be to fight wars for us. If they became slaves, someone would pull the same move the doctor did from Irobot. If robots had emotions, we'd be at a loss not a gain.
