Abstract

The invention provides a multi-mode touch sensing device, and belongs to the technical field of robot sensors. The multi-mode touch sensing device comprises a shell, wherein an image acquisition camera, a multi-array pressure sensor, multiple support structure components and a transparent elastomer are arranged in the shell, and the upper part of the transparent elastomer protrudes out of the toppart of the shell; the image acquisition camera is fixedly connected to the bottom part of the shell through a camera supporting plate; the multi-array pressure sensor is located above the image acquisition camera and is supported by the bottom part of the shell, the multi-array pressure sensor is provided with a light-transmitting hole, and the upper surface of the multi-array pressure sensor isprovided with transparent supporting blocks used for supporting the transparent elastomer; uniformly distributed light emitters are arranged on the periphery of the lower part of the transparent elastomer; and temperature sensors are arranged at the positions, protrudes out of the top part of the shell, of the periphery of the transparent elastomer. According to the multi-mode touch sensing device, the measurement of multi-mode information such as stress, texture and temperature is integrated in the same sensing device, and the touch sensing device has the advantages of being simple and compact in structure, high in measuring precision, capable of being repeatedly used and wide in application range.

Description

technical field [0001] The invention relates to a multi-modal tactile sensing device, which belongs to the technical field of robot sensors. Background technique [0002] The robotic dexterous hand needs to be able to perform various operations such as grasping, moving, pinching or fixing objects. During the operation, the tactile feedback of the dexterous hand must be used to achieve precise control of the operating force and avoid damage to the manipulated object. There are many kinds of conventional dexterous hand sensors, including piezoresistive, capacitive, photoelectric, etc., that is, the strength of the sensor can be judged by the change of resistance, capacitance, and light intensity under the applied force. However, these sensors have some shortcomings, such as sensors based on voltage or capacitance changes are sensitive to noise and temperature changes, and can only detect vertical force, not shear force. [0003] In order to overcome the above problems, vision...
