This master thesis revolves around the development of an aid for children with the handicap Cerebral Palsy. The children are usually born with the condition, which limits the child’s control of its muscles. They therefore have special needs regarding support and correcting of the body and to move around. The project is made in collaboration with the company Meyland-Smith, producer of aids for people with extended requirements. The project solution is based on extensive research within the context of the users, market and the company’s possibilities. The aid is developed to meet the company’s requirements about production as well as their possibilities on the competitive market. The product, Ugo, gives the child freedom to move around and to develop as an independent person. It aims to facilitate the movements that children with CP are not able to do on their own. The saddle seat on the aid gives the child a correct posture and enables the child to walk, even when he/she is unable to sustain balance. Ugo has an integrated motor to help the child change heights while seated, from the height of a kitchen bench to a comfortable walking height and to floor height, where the child is able to play or exit and enter the chair without assistance.
