A robot’s brain is a computer. It switches on the parts of the robot
that make it move and do certain tasks. The programmer programs the robot with information for each task. A simple task needs very complicated software and hardware.
The robots of today can talk, play football, walk upstairs, dance and even conduct an orchestra! A lot of robots can see and hear – using cameras and microphones with software that helps them recognize things. Some can even smell. Robots can’t think like we do, but some robots can solve problems. They collect information, and process it by comparing it to the data in their program. Then they “decide” which is the best solution. Some robots can also communicate with humans at a very simple level: their software can recognize people’s body language and how they use their voice. Now scientists have developed new software using human DNA as a model. They say it will give robots personalities and feelings.
