—To improve the operation and the flexibility of the robot hand, in this paper we presented a new type pneumatic flexible robot hand based on the pneumatic artificial muscles and active flexible bending joints which developed in the previous research. The robot hand is imposed of five three-joint fingers; the middle finger is on the datum axis with the(More)
—The surface roughness and material removal is investigated in electrorheological (ER) fluid-assisted polishing of tungsten carbide die. In this study, the microstructure of fibrous columns formed by particles perpendicular to the electrodes is observed by CCD when the electrical field is applied. The distribution of the electric field strength on the(More)
