This paper describes an exploratory case study about the applicability of different robotic platforms in an educational context with a child with Down syndrome. The robotic platforms tested are the humanoid robot KASPAR and the mobile robotic platform IROMEC. The study observed the effects KASPAR and IROMEC had in helping the child with the development and improvement of her social skills while playing different interactive games with the robots. Conceptually similar play scenarios were performed with both robots and the behaviour of the child was monitored during her interactions with them.
