The invention discloses a compact vowel preference keyboard layout, wherein eight vowels, namely a, o, e, y, i, u, v and w are placed in the middle row of a keyboard in the mode of bilateral symmetry to be used as the tabs of the index fingers, middle fingers, ring finger and little finger of two hands; the direction keys and page turning keys are placed in the middle to ensure two hands to apart from each other and comfort the operation; and 32 symbolic keys, 10 number keys and various function keys and letter keys are combined reasonably, thus the overall keys are controlled to 54 keys which are arranged in four rows and 14 lines and the full symmetric keyboard layout is smaller, more convenient and more efficient.

A glove of the present invention includes a stretchable member and protective members arranged on a side corresponding to a back of a hand, and when the glove is placed in a stationary state and viewed from the back side, the stretchable member forms two or more separate curve surfaces, and upper end portions thereof are located somewhere in lower half parts of finger covering parts, each of the curve surfaces formed with the stretchable member extends toward a wrist part, crossing a center line of at least one finger covering part selected from a second finger (forefinger) covering part, a third finger (middle finger) covering part, a fourth finger (ring finger) covering part, and a fifth finger (little finger) covering part, at least twice in a region from the upper end portions to a normal to the center line of the third finger (middle finger) covering part that passes an interdigit part between the first finger (thumb) covering part and the second finger (forefinger) covering part, and in regions between the curve surfaces of the stretchable member, the protective members are provided. This configuration makes it possible to provide a glove that is capable of following changes in shape caused by a gripping action of the hand, providing both of the feeling of fitting and the feeling of support, and having a high-level protection function and a high-level mobility function.

The invention relates to a rack type parallel coupling underactuated robot finger device belonging to the technical field of hand design of humanoid robots. The device comprises a base, a motor, a speed reducer, a proximal joint axle, a middle finger section, a distal joint axle, a tail end finger section, a coupling transmission mechanism, an underactuated transmission mechanism and a plurality of spring parts. The device comprehensively realizes the effective fusion of the coupled grasping effect and the selfadaptive underactuated grasping effect by adopting the motor, the gear rack coupling transmission mechanism, the gear rack underactuated transmission mechanism and the spring parts. The device has simple structure and no transition axle; and the transmission parts do not distort andare not pretightened, the transmission process is accurate, the appearance and the action process of grasping objects are similar to those of human fingers, and therefore, the device is suitable for being taken as fingers of a humanoid robot hand.

The invention discloses a manipulator with a motion controlled by a torsion spring and steering engines. The manipulator comprises a palm, a thumb, a forefinger, a middle finger, a ring finger and a little finger; an external part of the palm includes a hand back stopper, a hand back block, a palm block, a palm stopper and a thumb pressing block; the thumb pressing block is aslant inserted in a groove in the thumb position on the hand back block; the palm block is tightly combined with the hand back block and the thumb pressing block through a lap of limiting structures, and is locked with the same through a center bolt and a center nut in middle; the palm stopper and the hand back stopper are respectively clamped in grooves of the palm block and the hand back block for covering the center bolt and the center nut; and an internal part of the palm includes a steering engine bracket, five steering engines, five coil tillers, a thumb guide frame and a four-finger guide frame, wherein the five coil tillers are locked on output shafts of the five steering engines through screws. The manipulator is flexible and light in structure and simple and precious in control, improves the simulation capacity, and is low in cost and simple and beautiful in appearance.

A glove massager comprises an air bag component, an air pump, air valves, a circuit board and an outer shell. The air bag component comprises a finger massage portion which comprises a plurality of first air sacs at intervals corresponding to the index finger, the middle finger, the ring finger and the little finger. The air pump is communicated with the first air sacs through the air valves, thecircuit board controls on and off of the air valves so as to control the air pump to inflate and deflate the first air sacs, and thus, the first air sacs regularly expand to massage the fingers of a user. The two sides of each finger are extruded by the first air sacs on two sides of the corresponding finger, clamping massage is realized. Finger muscle relaxing is realized, finger blood circulation is promoted, and massage functions of hand massager products are enriched.
