    • Utilizing Bluetooth Low Energy to recognize proximity, touch and humans 

      Scheunemann, Marcus M.; Dautenhahn, Kerstin; Salem, Maha; Robins, Ben (Institute of Electrical and Electronics Engineers (IEEE), 2016-11-17)
      Interacting with humans is one of the main challenges for mobile robots in a human inhabited environment. To enable adaptive behavior, a robot needs to recognize touch gestures and/or the proximity to interacting individuals. ...
