Abstract :A tactile sensor mounted on a robot can make teh operation of the robot more intelligent . The st ructure and principal of a robot tactile sensor based on the outer modulation mechanism of a st rength type otical fiber sensor is int roduced in detail. Many experiment s were done to study the static and dynamic characteristics of a sensor , ,and the mathematical model was established as well. The result s showed that the could effectively sense the tactile sense and it could be used on a manipulator for soft-grasp.
Key words :tactile sensor ;optical fiber ;characteristic ;manipulator
