Description

The robot tendon-type four finger abducting device
Technical field
The invention belongs to anthropomorphic robot's technical field, particularly a kind of structural design of robot tendon-type four finger abducting device.
Background technology
People in research to intelligent robot, the tidemark of anthropomorphic robot as robot research, also always the behavior that realizes the class people as the target of dreaming of.And itself is the same with human, and most functions of anthropomorphic robot will realize by operation by human hand, thereby hand structure is anthropomorphic robot's important component part, and its design is one of key technology of anthropomorphic robot.
Most bending and two the initiatively frees degree motions of sides exhibition of adopting very complicated multi-gear transmission mechanism to be implemented in forefinger, middle finger, the third finger and little finger of toe root of existing Dextrous Hand (as the HIT/DLR hand of the V5 hand of U.S. Robonaut hand, Britain Shadow company, cooperation of China and Germany research and development and Beijing Institute of Aeronautics BH hand etc.), and should bending vertical mutually with the side moving center line of tossing about in bed.Its deficiency is: this apparatus structure complexity, the cost costliness because the number of motors of active drive is too much, has increased the weight of the difficulty of real-time control simultaneously.
For studies show that of staff, the side exhibition free degree motion of the forefinger of staff, middle finger, the third finger and little finger of toe is extremely important, when grasping familiar object (especially spherical body) and finishing some common gesture motion (for example " V " font gesture, " OK " gesture etc.), often need the four side exhibition motions that refer to.But in the time of most, the four side exhibition motions that refer to are carried out simultaneously, the side exhibition motion of a rare independent finger.Thereby Dextrous Hand possessed, and each finger all finishes side exhibition motion separately seems more " dexterity ", but control difficulty and manufacturing cost have been increased greatly.The four side exhibitions that refer to are moved and can be realized when grasping object that a kind of envelope of three-dimensional more grasps effect, make that extracting is more stable.
A kind of existing belt wheel under-actuated robot hand apparatus (Chinese invention patent CN101214653A) has 6 motor-driven palms of employing and 5 fingers, and each finger all adopts motor-driven belt wheel lack of driven structure to realize; Thumb has 3 frees degree: one is the side-sway joint between thumb and the palm, and two is the crooked free degree in the middle of the thumb in addition; Forefinger, middle finger, the third finger is identical with the little finger of toe structure, size is different, has 3 crooked frees degree respectively, comprising the root and the crooked free degree of the finger between the palm of a finger.Its weak point is: the forefinger of this robot, middle finger, the third finger and little finger of toe do not possess finger side exhibition motion, be difficult to when causing grasping familiar object realize that better three-dimensional envelope grasps effect, it is stable not enough to grasp object, is difficult to finish common gestures such as picture " V " font gesture, " OK " gesture simultaneously.
Summary of the invention
The objective of the invention is to design a kind of robot tendon-type four finger abducting device for overcoming the weak point of prior art.Closing up and side exhibition motion of forefinger, middle finger, the third finger and the little finger of toe of this device realization robot, make robot more multiple spot contact when grasping object, have better three-dimensional envelope and grasp effect, action when grasping object and doing gesture is more near staff, adopt less motor to realize the common side exhibition of a plurality of fingers simultaneously, to reduce control difficulty and manufacturing cost, be applicable to anthropomorphic robot's hand.
