Field of application

  • Research and development on service robotic technology at research institutes, scientific academies
  • The elderly assistance and rehabilitation training at welfare centers and rehabilitation hospitals
  • High-tech exhibition at science and technology museums and exhibition halls

Application Instance

From May till October in 2010, Jiao Long intelligent wheelchair participated in the exhibition at Life Sunshine Pavilion, Shanghai World Expo. The visitors who are elderly and disabled people experienced the convenient and intelligentized life the service robot technologies bring. The intelligent wheelchair can provide guide service of the tour around the exhibition hall for tourists, and communicate and interact with visitors. A visitor asked about an item on display, and the guide robot can find the shortest path and lead the visitor to the destination, introducing the item through voice and video.
