Technical field
The invention belongs to robot technical field, particularly a kind of twisted-pair feeder genlocing adaptive robot fingerThe structural design of device.
Background technology
Robot is one of most important assembly of robot, the crucial skill such as structural design and revising of the functions of robotArt is most important concerning robot. Existing robot mainly can be divided into anthropomorphic hand and non-anthropomorphic hand, both has non-Often application widely. Because people's hand is very flexible, powerful, on bionics, there is very large research learning to be worth, personificationThe exploitation of robot has very large prospect. Current humanoid robot hand is mainly divided into industrial clamper, Dextrous Hand and owes to driveStart.
On the one hand, robot need to realize crawl, carrying and operation difformity and size complex object, this forHave relatively high expectations in the aspects such as the control accuracy of robot; On the other hand, humanoid robot hand requires the spies such as size to fit, weight be littlePoint. Existing industrial clamper function is simple, and the scope of application is less. Existing Dextrous Hand has enough joints and driverBecome various accurate actions, but very complicated and expensive. And owe to drive hand because self the feature such as adaptivity is in certain journeyOn degree, solve this contradiction.
With the features such as self adaptation owe drive hand volume little, lightweight, can change and grab capturing in the process of objectGet the shape that angle adapts to object automatically with this, control simple, accurate, stable.
The robot device (patent of invention US2006129248A1) of existing a kind of self-adapting grasping object, finger partMainly comprise pedestal, four segments, three joint spring parts and a longitudinal tendon rope. While capturing object, first pull longitudinal tendon rope to makeMust point and stretch, then loosen longitudinal tendon rope, rely on joint spring part self elasticity to make to point bending envelope and capture object. Due to oftenIndividual joint all has joint spring part, finger capture in the process of object can matching object shape according to respective angles bending,There is good adaptivity.
This device weak point is:
1) the joint spring part grasp force of this device as far as possible large with stretch the pulling force of pointing longitudinal tendon rope used try one's best little betweenThere is larger contradiction. In order to ensure that grasp force is larger, the joint spring part stiffness factor needing is larger, causes pulling longitudinal tendon rope to be stretchedDirectly point required pulling force larger; If it is less to want longitudinal tendon rope to stretch the required pulling force of finger, adopt weak joint spring part,Grasp force is too small.
2) this device is difficult to the grasp force that provides wider. Fixing joint spring part, the crawl providing are provided this devicePower be confined to fix more among a small circle in; This device is the main grasp force that relies on joint spring part to provide in crawl object process,If joint spring part is more weak, just cannot utilize the strength of the arm being attached thereto, in the time extracting weight, can occur to capture and lose efficacy,When extracting very heavy luggage case, generally adopt arm strength to extract, but finger to there is enough strength to guarantee bendingConfiguration.
3) when the joint spring part of excessive stiffness factor may cause capturing object, there is finger and collide fast object, thereby leadCause and squeeze the unstable phenomenon that runs object.
4) this device uses to have and captures the possibility losing efficacy under vibration environment.
The pneumatic under-actuated robot finger device of existing a kind of self-locking (patent of invention CN103659825A), this device toolThere is self-adapting grasping function, adopt click to realize the self-locking in crawl process, and adopt motor to pull ratchet to realize release.
The weak point of this device is:
1) this device need to have motive force could realize self adaptation bending. This motive force is the relative fortune with object from fingerMoving: by the slide block on object extruding finger, to utilize strength transmission to promote next segment bending.
2) the lockable joint angles of this device is discontinuous. Because the gear teeth of ratchet have certain tooth pitch, locking is notContinuously; If tooth pitch designs to such an extent that reduce locking precision compared with conference, if tooth pitch designs littlely, can reduce tooth depth, impact lockDetermine effect.
