I found amazing video on Youtube.
↑click it or copy & paste it. I am sure you will be amazed!
In U.S.A., dog robot have been created. It is named ALPHA DOG.
When I was watching the video, I felt that our robot technology has developed because even though 2 guys pushed the robot, robot did not fall over AND it can stand up even thoght it is fallen over. IN ADDITION it can move any roads such as rocks, snow, even frozen roads. MOREOVER, it can carry stuff within 180 kg (4E and 02 lb).
There have been many challenging to develop robot technology. well-developed technology could make us create greater comfort in life. However, I think it is kind of scary things because I found another news. It talks about that technology will divert into Navy.
