Tday’s rbt revlutin(革命) is t make rbts fr everyday use.Rbts will d basic husewrk such as cleaning r gardening， r just helping yu have mre fun n the basketball curt. What makes a rbt different frm an rdinary machine is the ability t sense and make changes t the envirnment.Fr example， a flr-cleaning rbt shuld be able t sense yur scared cat and mve ut f the way.
Tday’s cmputing ability is， fr the first time， able t make machines that culd “think”， at least in certain ways. Hwever， there are als wrries that rbts will ne day take the place f humans t be the master f the wrld.What will the future be like? Let’s wait and see!
