Why do we need robots?
Robots can be programmed to do complex work that are hard for humans to tackle or work in high risk or extreme conditions such as the rovers on Mars. Since robots are driven by electrical and mechanical energy, they are just like machines that accomplish complex tasks efficiently.
Para que precisamos de robôs?
Os robôs podem ser programados para fazer trabalhos complexos que são difíceis para os seres humanos, ou trabalhar em condições de alto risco ou extremas, como as sondas em Marte.
