Recent developments in artificial intelligence (AI) and robotics point to a close future collaboration between humans and machines. Even though the use of personal robots is not yet a phenomenon, findings in technical and legal literature highlight several possible risks inherent in the processing of personal data by such robots. This article contributes to the current discussions on the applicability of the GDPR to AI technologies from three aspects: (i) first, it encourages the use of a scenario method to predict possible future legal problems related to new technologies; (ii) second, it analyzes considerations with the support of the relevant case-law and present comparative expert opinions for overcoming the weak points of the GDPR relevant to AI; (iii) and finally, proposals made in the recommendations part aim to contribute to a better application of the GDPR to AI technologies in personal use.
