I bought a new book on robot design and read a chapter. The author shared three interesting stories: When the author was on the pepper team, every time pepper rebooted, it was very difficult. The engineers would cheer it on, and when they saw it start up, they would cheer with joy. It turns out that humans also feel happiness when helping robots. When pepper went to France, it couldn't communicate properly due to language settings and could only ask for hugs. The French people initially had some distance from the robot, but when they saw pepper asking for a hug, they would actively go to hug it, and some even kissed pepper. The elderly in the nursing home felt that it was okay if pepper answered questions incorrectly, but they hoped that pepper's hands would be warm. Because it was their companion for sharing and companionship. Therefore, the author left the pepper team to create a robot that, although it couldn't improve human efficiency, could bring happiness to humans. This led to the later creation of lovot.
