Problems solved by technology

However, the disadvantage of this type of sensor is that there are many leads, the circuit is complicated, and wiring and manufacturing are very difficult.
In practical applications, there is mostly rigid contact between the sensor and the operating target, resulting in low detection accuracy, unsatisfactory operation shock absorption and stability

Abstract

The invention relates to a tactile sensor based on elastomer three-dimensional deformation and a detection method. The sensor part mainly comprises an elastomer, a binocular camera and a lighting source, wherein the binocular camera and the lighting source are both located above the elastomer; the binocular camera acquires image information through deformation of the elastomer and the contact force can be solved; and then, the direction and the distribution of the contact force are calculated. Through designing a brand new structure, the three-dimensional deformation of the elastomer is acquired for analysis and calculation to obtain the size and the direction of the contact force, the structure is simple, wiring is convenient, and the whole cost can be greatly reduced.

Description

technical field [0001] The present invention relates to the related technical field of tactile sensors, in particular to a tactile sensor based on three-dimensional deformation of an elastic body and a detection method. Background technique [0002] Tactile sensors are used in a wide range of applications, most commonly based on sensor arrays for detection. However, the disadvantage of this type of sensor is that there are many leads, the circuit is complicated, and wiring and manufacturing are very difficult. In practical applications, the sensor and the operating target are mostly in rigid contact, resulting in low detection accuracy, unsatisfactory operation shock absorption and stability. [0003] Therefore, it is necessary to design a new tactile sensor to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide a tactile sensor based on the three-dimensional deformation of elastic bodies in order to overcome the...
