Although several robotic/intelligent wheelchairs have been proposed recently,they consider friendliness only to their users. Machines like wheelchairs interact various people other than their users. They must consider friendliness to all these people. This paper presents a robotic wheelchair that cares for all relevant people: users, pedestrians, and caregivers, by looking at these people. It looks at the user's face, observing its direction. The user can turn it by looking in his/her desired direction. It looks at pedestrians and changes the way of avoidance against them depending on whether or not their noticing it. In addition, it looks at the caregiver when he/she is with it and keeps moving with him/her.
