The project uses current theory and technology in human communication, computer communication and dialogue systems to develop a toy that is fun and interesting for young people with communicative disabilities. The toy helps the development of dialogical communication, an area that is normally problematic for these children. Children with severe disabilities often have few opportunities to play independently and to interact on equal terms with children without disabilities, and here Lekbot enables children with and without disabilities to interact and learn from each other.

The Lekbot toy developed in the project is a radio-controlled robot that can be used by children with severe physical and/or cognitive disabilities, such as cerebral palsy or autism. The robot is controlled by the child through touch-screen symbols. The symbols are translated into spoken language, so that the touch screen "talks" to the robot and acts as the child's voice. The robot can, in turn, talk to the child using spoken language, and the child can again answer using the touch screen.

The robot is built using Lego Mindstorms NXT, and the dialogue system is developed using GoDiS. The project is supported by Acapela, whose speech synthesis is used for both the touch screen and the robot.
