Like, for example, what if it could go to a dinner party at the White House?  So, because we were interested more in the system design and the user interface than in the hardware, we decided that, rather than have a robot replace the human to go to the party, we'd have a human replace the robot.
比如，如果它走到白宫 去参加一个晚宴？ 于是，因为我们更感兴趣的是系统设计 以及用户界面而非硬件 我们决定，并非是要 机器人代替人去参加聚会， 我们会有人代替机器人去。
