Embodiment Construction

[0021] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0022] Such as image 3 As shown, in an example of the present invention, it includes a housing, an infrared light emitting module 7, an infrared light emitting lens group 8, an infrared light receiving lens group 9, an optical signal processing unit 10, a signal transmitting unit 11, and a platform 12, Motor (constant-ratio parallel shaft gearbox) 13, slip ring and corresponding drive circuit.

[0023] (1) After receiving the measurement command, the infrared emitting module 7 drives the infrared LED to emit infrared rays by means of current modulation, and after being focused by the infrared light emitting lens group 8, it directly shoots into the environment.

[0024] (2) Infrared light propagates in the air, and is reflected and scatte...

Abstract

The invention discloses a small-size infrared obstacle avoidance early warning device, which comprises a housing, an infrared light emission module, an infrared light emission lens group, an infrared light reception lens group, an optical signal processing unit, a wireless signal emission module, a drive motor, a constant proportion parallel-axis gear box, a slip ring, a pan & tilt and a corresponding drive circuit. The device is accurate to measure information of distance and size and the like of an obstacle object, is small in overall system size, compact in structure and low in production cost, and can realize later software optimization and upgrade.

Description

technical field [0001] The invention relates to the field of intelligent obstacle avoidance and positioning of a small robot, in particular to an obstacle avoidance and positioning system and method for an intelligent robot. Background technique [0002] Environmental map drawing and obstacle avoidance are important research topics in the field of intelligent robots. In order to better complete tasks, intelligent robots need to generate a map of their working environment, and then plan the most reasonable working path based on the understanding of this environmental map. , Reasonably avoid obstacles in the work project. [0003] At present, the existing intelligent robot map drawing and obstacle avoidance methods on the market are mainly based on ultrasonic ranging obstacle avoidance technology or laser ranging obstacle avoidance technology. [0004] The ultrasonic ranging method first sends out ultrasonic waves from the ultrasonic generator, and returns to the receiver whe...
