This study aims at development of Intelligent McKibben actuator with embedded soft displacement/pressure sensors and micro valves. In this report, a soft pressure sensor made of rubber and conductive film was developed and embedded in McKibben actuator. By measuring the electrical resistance of the conductive film which changes following the deformation of the rubber with internal pressure change of the actuator, the pressure can be estimated The results of fundamental experiments to clear the characteristics of the sensor showed that it has drift phenomenon by influence of the rubber creep behavior. Therefore, we tried to apply the mechanical model to the sensor model. A 2-Voigt mechanical model which consists of two springs and two dampers could agree the sensor characteristics. Using the model, we carried out the servo control experiments. The results indicated the high efficacy of the model. Furthermore we expect that the modeling method will be able to contribute to improving accuracy of several soft mechanisms.
