With the continuous development of today's technology and the popularity of automation, intelligent handling robots, as an important tool for enterprise automation transportation technology, have been very well established from a technical point of view and are widely used in various industries. Intelligent handling robots can ensure the safe and accurate, intelligent and efficient transportation of raw materials to their destinations. Therefore, intelligent handling robots have also derived a variety of navigation methods, and we can next analyze the mainstream navigation technologies of intelligent handling robots in recent years.
Popular navigation technologies of intelligent handling robots
1、Magnetic stripe navigation
Magnetic stripe navigation is a navigation method with more perfect technology at this stage. One of the main applications is to lay the magnetic stripe on the operation line of the handling robot, and then the intelligent robot obtains the error between the machine itself and the target tracking path according to the electromagnetic field data signal on the path, and then after precise and reasonable calculation and measurement, so as to complete the navigation of machine transportation.
The advantages of magnetic stripe navigation compared to other navigation technologies are low price and cost, perfect technology, accurate and reliable positioning, and other advantages. The disadvantage of magnetic stripe navigation is the corresponding preparatory work, must have certain installation settings for the operation route, requiring a certain amount of labor and time costs; and the magnetic stripe is easy to lose; and if the work line changes, the magnetic stripe paved on the line also needs to change; and the high cost of quality maintenance disadvantages.
2、Magnetic nail navigation
The magnetic nail navigation application principle is based on the magnetic data signal received by the navigation sensor from the magnetic nail to find the positioning driving path, in which the distance between the magnetic nail can not be too large, and in between two magnetic nails, the handling robot will be in the state of encoder calculation.
The common module of magnetic nail navigation is almost the same as the magnetic stripe navigation module. The advantages of magnetic nail navigation are low price and cost, perfect technology, good concealment of magnetic nails, strong anti-interference ability, and resistance to wear and tear, and can be used in indoor and outdoor applications. The defect of magnetic nail navigation is the preparation work is larger, change the operation route, we need to second paving route; and magnetic nail navigation paving project will also cause some damage to the road and other disadvantages.
3、Slam laser navigation
Slam laser navigation is the most advanced navigation technology used by intelligent handling robots at this stage. This technology mainly uses two-dimensional laser scanner to carry out accurate measurement of the current environment and create the current navigation environment. Without information about the surrounding environment, it allows the robot to familiarize itself with the surrounding environment and construct a topographic map of the environment based on its own sensors.
Compared with other navigation technologies, the advantages of Slam laser navigation are that it does not require ground engineering construction, which is convenient for enterprise applications and facilitates later line changes; and its strong sensing capability can adapt well to the environment and can also avoid obstacles instantly; the advantages of easy construction and short cycle time of navigation. The disadvantage of Slam laser navigation is that the positioning is not as accurate, it is easy to lose the positioning accuracy in some complicated terrain environment, and it is influenced by the environment.
