The ongoing development of robotics against the background of a decreasing number of care personnel raises the question which contribution robotics could have to rationalize and maintain, or even improve the quality of care.
A systematic review was conducted to assess the effects and consequences of the interaction between socially assistive robots and elderly, in published literature. We searched in CINAHL, MEDLINE, The Cochrane Library, BIOMED, PUBMED, PsycINFO, EMBASE and the IEEE Digital Library. In addition, articles were selected through free Internet search and from conference proceedings.
Studies have been found reporting positive effects of companion type robots on (socio)psychological level and physiological level. However, the scientific value of the evidence is limited due to the fact that most research is done in Japan with a small set of robots, with small sample sets and with mostly an explorative approach.
