In recent years, mobile robot technology has been greatly developed in the world, and the navigation technology of robot has also been developed rapidly, from the former magnetic stripe navigation, two-dimensional code navigation, to the popular laser trackless navigation.
For lasaer pointer trackless navigation which does not need to lay magnetic stripes on the ground, it is divided into reflector navigation and natural contour navigation (no reflector).
The reflector navigation is to place the reflector at a certain distance around the driving path of the mobile robot. The laser scanner on the robot emits a laser beam and then collects the reflected laser beam.
According to the reflected laser beam data, the robot’s current position in the environment is determined, and the robot can walk autonomously with the help of controller and algorithm.
However, the placement of reflectors around the production site will affect the site work progress to some extent and increase the implementation cost for enterprises.
The so-called natural contour navigation (no reflector) is based on the navigation principle of SLAM. SLAM (simultaneous localization and built figure) in unknown environment, the robot by itself carries the internal sensor (encoder, innovative marketing, etc.) and external sensors (laser sensor and visual sensor) to position itself, and use external sensors on the basis of the positioning of the construction of the environmental information incremental environment map.
Xianzhi robot, a high-tech enterprise in the field of mobile robots, independently developed 3D SLAM laser navigation technology without reflector plate, which requires no other positioning facilities on the ground and is flexible and convenient, realizing accurate positioning and rapid deployment of robots in complex environments.
