What happens here is that the brain activity that generated the movements in the monkey was transmitted to Japan and made this robot walk while footage of this walking was sent back to Duke, so that the monkey could see the legs of this robot walking in front of her.
猴子大脑的活动发出运动指令 传到日本，并且控制这个机器人的行走 行走的镜头被发送回杜克 所以，猴子能看到机器人的双腿就在眼前行走
