Description
One, technical field
The invention belongs to virtual reality technology and teleoperation robot technical field, is a kind of man-machine touch interface devices, relates in particular to a kind of flexible tactile sensor.
Two, background technology
Along with virtual reality technology and interactive teleoperation robot broad application, power is felt and the human-computer interface device of tactile feedback effect with a large amount of the having of needs.Tactile sensor is exactly the important human-computer interface device of a class, and in virtual reality system, the operator can touch dummy object in the virtual environment, tactile characteristics such as the flexibility of perception dummy object, rigidity, superficial makings truly by this device; In teleoperation robot system remote operation process, it can be with the end effector of robot effective object (as the muscle in the remote operation, tissue, organ, objects such as tumour) tactile data feeds back to operating personnel, and reproduce the flexibility and the rigidity of object at operator's finger tip, thereby make the operator produce the tactilely-perceptible effect of " on the spot in person ", own seemingly just at the scene with finger exploration effective object, the just physical characteristic of judgment object and classification exactly of operator like this, for example, in the tele-medicine process, just can judge the position and the size of tumour and whether have key character such as coating according to this tactile sensor.
Three, technology contents
Technical problem: the invention provides and a kind ofly can improve the perception sense of reality and perception velocities and flexible tactile sensor simple in structure.
Technical scheme: the present invention is a kind of flexible tactile sensor that is used to feel the object situation, comprise support, on support, be provided with supporting, be connected with tabular spring beam in supporting, and have at least a supporting to be connected with tabular spring beam by leading screw, silk wheel, the sliding sleeve of establishing thereon, leading screw is threaded with the silk wheel, sliding sleeve is connected with the silk wheel, sliding sleeve and tabular spring beam are slidingly connected, and leading screw also links to each other with the output shaft of motor, are provided with the perception cap on tabular spring beam.
Technique effect: 1. the tabular spring beam of the present invention's employing is simple in structure, and size is little, is easy to processing and installation, therefore is easy to realize three-dimension flexible tactilely-perceptible structure.Utilize tabular spring beam to control quantitatively, accurately and apace and will express the rigidity of object, flexibility or rigidity that this flexible tactile sensor based on tabular spring beam allows the people perceive are a kind of continually varying analog quantitys, so the operator can distinguish exactly have identical shaped and big or small, and the different object of surface flexible (virtual objects or far the real object of robot contact); And original tactilely-perceptible technology can only provide the perception of switching value sense of touch, surface configuration and size that people can only perceptive object, true flexibility or rigidity that can't perceptive object.The rigidity of spring beam is inversely proportional to 3 powers with effective flexural deformation length l of spring beam, that is:
