Description
Technical field
The invention belongs to robot technical field, more particularly to a kind of twisted-pair feeder genlocing adaptive robot finger
The structure design of device.
Background technology
Robot is one of most important component of robot, the crucial skill such as the structure design and function of robot are improved
Art is most important for robot.Existing robot can be divided mainly into anthropomorphic hand and non-anthropomorphic hand, and both are owned by non-
Often it is widely applied.It is powerful because the hand of people is very flexible, there is very big research learning value on bionics, it is anthropomorphic
The exploitation of robot has very big prospect.Current humanoid robot hand is broadly divided into industrial clamper, Dextrous Hand and owes to drive
Start.
On the one hand, robot need realize crawl, carry and operation different shape and size complex object, this for
Require higher in terms of the control accuracy of robot;On the other hand, humanoid robot hand requires the spies such as size is suitable, weight is small
Point.Existing industrial clamper function is simple, and the scope of application is smaller.Existing Dextrous Hand has enough joint and driver
Into various accurate actions, but extremely complex and costliness.And drive lacking hand due to itself adaptivity the features such as in certain journey
This contradiction is solved on degree.
With it is adaptive the features such as drive lacking hand small volume, lightweight, can change during object is captured and grab
Take angle with this automatic shape for adapting to object, control is simply, accurately, stably.
A kind of robot device (patent of invention US2006129248A1) of existing self-adapting grasping object, finger part
Mainly include pedestal, four segments, three joint spring parts and a longitudinal tendon rope.When capturing object, longitudinal tendon rope is first pulled to make
Obtain finger to stretch, then loosen longitudinal tendon rope, digital flexion envelope is captured object by joint spring part natural resiliency.Due to every
Individual joint all has joint spring part, and finger can be bent during object is captured with matching object shape according to respective angles,
With good adaptivity.
The device is disadvantageous in that:
1) the joint spring part grasp force of the device try one's best greatly with stretch used in finger the pulling force of longitudinal tendon rope try one's best it is small between
There is larger contradiction.In order to ensure grasp force it is larger, it is necessary to joint spring part stiffness factor it is larger, cause to pull longitudinal tendon rope to stretch
Pulling force needed for straight finger is larger;Pulling force needed for stretching finger to longitudinal tendon rope is smaller, using weaker joint spring part, then
Grasp force is too small.
2) device is difficult to provide larger range of grasp force.The device using fixed joint spring part there is provided crawl
Power is confined in fixed smaller range;The device relies primarily on the grasp force that joint spring part is provided during crawl object,
If joint spring part is weaker, the strength for the arm being attached thereto can not be just utilized, crawl failure can occur when extracting weight,
It is general to be extracted using arm strength when such as extracting very heavy luggage case, but finger will have enough strength to ensure bending
Configuration.
3) the joint spring part of excessive stiffness factor may cause generation finger during crawl object quickly to collide object, so as to lead
Cause to squeeze the unstable phenomenon for running object.
4) device is under vibration using the possibility for having crawl failure.
A kind of existing self-locking pneumatic under-actuated robot finger device (patent of invention CN103659825A), device tool
There is self-adapting grasping function, the self-locking during crawl is realized using click, and pull ratchet to realize unblock using motor.
The device is disadvantageous in that:
1) device, which needs motive force, could realize adaptive bending.Relative fortune of this motive force from finger and object
It is dynamic:Sliding block on finger is extruded by object, promotes next segment to bend using pneumatic power drive.
2) the lockable joint angles of the device are discontinuous.Because the gear teeth of ratchet have certain tooth pitch, locking is not
Continuously;If tooth pitch is designed to compared with conference reduction locking precision, if tooth pitch is designed to smaller, it is high to reduce tooth, influence lock
Determine effect.
