Problems solved by technology

[0005] Using the existing mobile robot platform, it is difficult to realize the ranging function of obtaining 360° omnidirectional information at one time. To achieve omnidirectional ranging, the mobile robot platform or sensor needs to be rotated, which will not only increase the complexity of the control algorithm , and will also reduce the positioning accuracy and real-time performance of ranging

Embodiment Construction

[0050] In order to make the purpose, technical solution and advantages of the present invention clearer, the implementation manners of the present invention will be further described in detail below.

[0051] A mobile platform with omni-directional ranging capabilities, see figure 1 , including: mechanical structure 1 and hardware structure 2. Among them, the mechanical structure carries various components such as power supply, motor, sensor and hardware module used. In order to better realize the motion index of the mobile platform, the design of the mechanical structure mainly considers the body design, wheel layout and the space position requirements for the installation of each module. The hardware structure is a circuit module built according to the requirements of the motion control function and distance measurement function to be realized.

[0052] see figure 2 , the mechanical structure 1 adopts a three-layer structure (the embodiment of the present invention takes...

Abstract

The invention discloses a mobile platform with omnidirectional distance measuring function and a distance measuring method thereof. The mobile platform comprises: an epoxy resin board is arranged on the bottom layer, and a first layer of aluminum board and a second layer of aluminum board are sequentially arranged above the epoxy resin board. , the bottom of the epoxy resin board is provided with supporting wheels and driving wheels; the power module is arranged on the epoxy resin board, and the control module, phase detector module and driving module are arranged on the first layer of aluminum board; the ultrasonic module and the radio frequency module are arranged on the second layer The two-layer aluminum plate; with the control module as the center, the phase detection module and the drive module complete the movement function of the mobile platform; the ultrasonic module and the radio frequency module complete the distance measurement function of the mobile platform. The ranging method includes: after the mobile platforms A and B confirm the ranging information, the mobile platform A sends out an ultrasonic signal and starts timing, stops the timing after receiving the ultrasonic signal from the mobile platform B, and measures the ranging distance. The invention avoids the requirement of time synchronization for distance measurement, and improves the accuracy and real-time performance of distance measurement.

Description

technical field [0001] The invention relates to the field of ranging, in particular to a mobile platform with an omnidirectional ranging function and a ranging method thereof. Background technique [0002] With the development of social productivity and the advancement of modern science and technology, people put forward higher requirements for the positioning ability of mobile robots. Fast and accurate positioning has become the prerequisite for the wide application of mobile robots in the fields of industry, service industry and logistics. [0003] Existing positioning research is mainly divided into ranging-based positioning and non-ranging-based positioning, among which ranging-based positioning is widely used due to its high positioning accuracy. The ranging technologies currently used by mobile robots mainly include ultrasonic technology, infrared technology, laser technology and vision technology. [0004] The inventor finds in the process of realizing the present i...
