Fine motor force discrimination may serve as a valid and objective assessment of the skills required for successful needle insertion when placing central lines.

The article addresses the technical principles of a new interactive Robotic device, called Write Tutor, and gives an overview of its application. In spite of the various measures and efforts taken in terms of improving literacy rate we still have a major section of the population who are not able to read and write. The Write Tutor, a completely autonomous device can teach children and people of any age group the art of writing. The mechanism is programmed with speech recognition system and makes the user write what he speaks holding his wrist. It also can make you draw pictures in the graphical mode. The Write tutor also has built-in modules to teach reading and writing simultaneously using its on board display. The workspace is designed enabling the user to write on a sheet size varying from a post card to an A4 sheet. Therefore the Write Tutor is a low cost device that can be programmed to teach people in different languages, people who are physically challenged, autistic and dyslexic children and children in elementary schools.
