Background technology
Hand is one of most important organ of people, and in the anthropomorphic robot field, robot is vital link equally, and it is one of key technology of robot field that its structural design and function are improved.On the one hand, robot need be accomplished compound actions such as extracting, carrying, therefore needs comparatively accurate controlling mechanism; On the other hand, the personification of robot requires to have determined characteristics such as its volume is little, in light weight.Existing Dextrous Hand has enough pass joint numbers and drives number accomplishing accurate action, but very complicated, expensive.Also there are many technical barriers in the robot field at present.Owe to drive hand and solved this contradiction to a certain extent.
The coupled mode under-actuated finger adopts the crooked simultaneously coupling of multi-joint to grasp pattern, is rotated simultaneously by a certain percentage by a plurality of joints of driver drives.This pattern and the action of staff grasping objects are similar, and personification property is better, and the extracting process is more stable.The weak point of coupled mode finger is: pattern is comparatively fixing, can't adapt to difform object, generally to grip the mode grasping objects, is difficult to realize gripping Grasp Modes for large sized object, and grip is bad.
The self adaptation under-actuated finger adopts the pattern of self-adapting grasping, by joint of a driver drives, all the other joints finger with just begin rotation after object contacts.This finger can change the extracting angle according to the difformity of object, grips Grasp Modes thereby reach, and simple in structure and control is stablized.The weak point of self adaptation under-actuated finger is: finger is not solid form when contacting object, and anthropomorphic effect is relatively poor; Need in the process of contact object, produce driving force, possibly cause left knee stressed excessive, be unfavorable for grasping the far-end dactylus; Can't realize gripping Grasp Modes for small-size object, grip is restricted.
To coupled mode finger and self adaptation under-actuated finger weak point separately; A kind of new type compound that both are combined is owed to drive the extracting pattern and is suggested; This extracting pattern is: finger moves according to CGCM earlier before running into object; The motion of left knee is limited by object after the contact object, and this moment, the far-end dactylus continued to contact object with the adaptive model grasping objects fully until each dactylus.
