A robot UD1 has been developed which allows children with cognitive disorders like Down's syndrome to cope with their early child mobility issues. This can be done by using a robot to move about. Other normal children who are more mobile, seeing whem a disabled child may develop complexes. It helps them stay safe while moving about as the robot is containing sensors which can detect obstacles and move in a safe distance from them by navigating properly.
Thats cool. Version UD2 would also let an adult control the robot apart from the child ( 7 months child can use it) and the automatic control which would enable parents to train the kids in complex movements leading to enhanced cognition.
