About AGV
AGV (Automated Guided Vehicle) refers to a transport vehicle equipped with automatic guidance devices such as electromagnetics or optics. It can drive along the prescribed guidance path and has safety protection and various transfer functions. The application of AGV is It has the advantages of high degree of automation, efficient application, beauty and convenient use, and improving the corporate image.
With the development of industrial informatization and the increasing demand for intelligence of manufacturing equipment, AGV robots can adapt well to the development trend of flexibility, intelligence and informatization of modern manufacturing technology, so that the manufacturing industry has made a qualitative leap in production organization, information management and logistics technology. With the industry With the rapid development and the continuous expansion of the application range of AGV, the AGV system can be widely used in industry, military, transportation, electronics and other fields, and has good environmental adaptability.
The calibration of AGV
The navigation accuracy (positioning accuracy, repeated positioning accuracy, linear offset), movement speed, acceleration, parking accuracy, minimum rotation radius, etc. of AGV are important indicators of the product, which are all important parameters that need attention in the daily application of AGV. These parameters need to be measured and diagnosed regularly, so as to understand the performance of AGV at all times and ensure that it is in the best working state.

API Laser Tracker AGV Measurement Solution
In order to meet the detection needs of various parameters of AGV, in addition to high accuracy, measurement equipment is also required to have good dynamic performance, which is difficult to achieve by traditional measurement methods.
The application of API's Radian and iLT series laser trackers solves the problem of AGV dynamic detection.
The API laser tracker has an ultra-high data collection rate of 1000Hz (1000 points/second), which can fully meet the needs of static and dynamic detection of AGV carts. In addition, the measurement range of more than 160 meters can also meet the detection and calibration of AGV's active parameters in a large range.
Measurement and implementation
Usually, during measurement, the API laser tracker can be placed in a suitable position on the site, and then the tracker target ball (SMR) can be fixed on the self-rotating mechanism of the target ball developed by API. The laser tracker shoots the laser to the center of the target ball and locks the tracking. The static collection can be set according to the needs (AGV cart Static measurement after stopping at the position to be tested) or dynamic measurement (real-time measurement in the AGV car movement) to achieve and achieve the purpose of detection.

ActiveTarget and STS six-dimensional sensor
In addition to cooperating with the target ball to achieve data collection, the API series laser tracker can also cooperate with the ActiveTarget active target to realize the reverse locking of the laser, that is, while the laser tracker locks the target, the target will also automatically reverse lock the tracker and automatically turn to the laser direction during the movement, not It will cut off the light, so as to achieve faster and more coherent measurement, which is very friendly to the application scenario of high-speed trajectory measurement.
The STS six-dimensional sensor further realizes the measurement of 6DoF on the basis of the automatic reverse locking function of ActiveTarget active target, that is, in addition to measuring the spatial parameters of X, Y and Z at one time, it can also measure the parameters of swing angle, pitch angle and rolling angle at the same time to obtain the position. And posture data.

Tailor-made, collaborative development
At the same time, API can be software developed according to the personalized needs of AGV manufacturers for measurement. It provides data collection and analysis modules with reference to national standards and custom standards of enterprises. It can measure and record the positioning accuracy, repeat positioning accuracy and straightness performance of AGV movements and display them in real time, providing flexible on-site coordinates. The method software can define the start, termination position, operation increment, number of cycles, etc. of measurement positioning accuracy, and at the same time, it can measure the two-way straightness of operation. And provide real-time display of parameters such as speed and acceleration.
