Problems solved by technology

[0003] The tactile function of the robot realized by this method has the advantages of large area, high sensitivity and good flexibility, but it also has obvious disadvantages: first, the sensing cloth needs to be squeezed and deformed in actual use to achieve the effect of tactile detection , can not sense slight touch; secondly, because the sensing fabric has a certain thickness, it cannot be well wrapped in many special positions on the robot, and it is not easy to install; thirdly, wearing sensing clothing on the surface of the robot will affect the overall appearance of the robot, Make the surface of the robot a single material

Embodiment 1

[0021] like figure 1 As shown, an embodiment of the present invention provides a tactile sensor used on a robot, including a tactile detection chip, a signal acquisition circuit and a flexible circuit board. The VSS pin of the tactile detection chip is grounded, and the VDD pin is connected to the power supply; the Q pin is the signal output terminal, which is connected to the signal acquisition circuit for signal acquisition by the host computer; the I pin is the signal acquisition terminal, and is used as a tactile sensation carrier. The flexible circuit board connection is used to receive tactile sensing signals.

[0022] As an improvement, a parallel capacitor can be connected to the signal collection end of the tactile detection chip to adjust the sensing sensitivity of the tactile sensor. The capacitance of the parallel capacitor can be 0-50pF, the lower the capacitance, the higher the sensitivity, and the most sensitive state is when the parallel capacitor is not conne...

Embodiment 2

[0027] The present invention can be well applied to the display robot. The display robot is a multi-functional intelligent robot, which is used for publicity and guidance in various exhibition sites, stadiums and science and technology halls. It has functions such as walking, automatic navigation, shielding, and talking with people. However, because its outer casing is mostly made of plastic or glass fiber reinforced plastic, it is difficult to achieve tactile functions in the past.

[0028] An embodiment of the present invention provides a display robot, including a robot body and a tactile sensing system. like image 3 As shown, the tactile sensing system includes a host controller, a sensor acquisition board and a plurality of tactile sensors; the plurality of tactile sensors are respectively connected with the sensor acquisition board, and the sensor acquisition board is connected with the host controller.

[0029] Specifically, the plurality of tactile sensors are respe...

Abstract

The invention relates to a touch sensor, a touch sensing system and an intelligent robot. The touch sensor comprises a touch detection chip, a signal acquisition circuit and a flexible circuit board. A signal acquisition end of the touch detection chip is connected with the flexible circuit board, and a signal output end of the touch detection chip is connected with the signal acquisition circuit. The flexible circuit board serves as a touch sensing carrier, the touch key chip is adopted to achieve a touch sensing detection circuit, and a touch sensing function of the robot can be realized. Compared with an existing touch sensing garment, the touch sensor, the touch sensing system and the intelligent robot have the advantages that flexibility and changeability in shape are achieved, and changing shapes and areas according to practical utilization requirements can be realized; sensitivity can be adjusted accordingly to the thickness of a shell in practical use; the sensing carrier is light and thin and can be simply and conveniently mounted at various places and especially mounted in a shell of the robot without changing appearance of the robot; touch sensing can be realized without extruding deformation in touch.

Description

technical field [0001] The invention relates to the field of robot sensors, in particular to a tactile sensor, a tactile sensing system and an intelligent robot. Background technique [0002] Robotic sense of touch occupies a very important position in the robot sensory system, and it has functions that other senses such as vision cannot achieve. An article titled "Research on a New Type of Intelligent Robot Tactile Sensing Clothing" published in the "Sensing Technology Journal", Vol. 19, No. 3, 2006, announced a robot using the piezoresistive properties of conductive rubber. tactile method. Conductive rubber is made by infiltrating conductive particles into ordinary rubber. Its piezoresistive properties refer to the property that the resistivity of the conductive rubber per unit volume changes significantly under external forces. Generally, when the pressure on the conductive rubber gradually increases, Its volume gradually decreases, which is equivalent to an increase in...
