The combination of robots and emerging technologies such as cloud computing, big data, artificial intelligence, and the Internet of Things has innovatively built an intelligent manufacturing system, realized lean, flexible and intelligent production of industrial manufacturing, and greatly improved the level of intelligent manufacturing and production efficiency. With the rapid development of robot technology and the continuous expansion of application fields, it is particularly important to calibrate the robot with the help of advanced 3D digital means to ensure the high performance, high quality and high reliability of the robot.
Robot equipment needs to be rigorously calibrated before it is officially deliveredEnsure that its accuracy and performance meet the requirements。At the same time, in the process of robot operation, due to the influence of various factors, the robot's posture may be deviated, if not calibrated in time, it will lead to inaccuracy and reduced work quality of the robot when performing tasks, so it needs to be calibrated regularly to ensure that it can perform complex tasks stably and reliably.
Robot calibration is the process of improving the accuracy of robots, including joint angle calibration, motion alignment, and non-motion alignment.
01 Joint angle calibration: The robot's joint angle calibration is to compensate for the position and angle of the robot's joints so that they are consistent with the intended movement. The accuracy and repeatability of the robot can be improved by aligning the joint angle.
02 Kinematic calibration: Involves the geometry of the entire robot, including angular offsets and joint lengths.
03 Non-athletic school approval: Model errors outside of the geometric defaults, such as stiffness, joint compliance, and friction.
Sikan TechnologyM-Track intelligent robot path planning and guidance systemIt can be used to accurately obtain the position and attitude of the robot, and assist engineers in calculating key parameters such as coupling ratio, reduction ratio, axial deviation, linkage length, rotation angle, etc. Let's take a look at this caseHow to use m-track to ensure the accuracy of cobots
Founded in 2013, Shenzhen Zhongwei creates technology technology and production of consumer robot systems, founded in 2013, in the robot underlying algorithm, servo system, control system, robotic arm joint design, robotic arm design and other aspects have in-depth research and years of accumulation, products are widely used in education and research, unmanned retail, automatic detection and other fields.
Accuracy calibration is a key step before the delivery of Zhongwei created robots, and the traditional method can only adjust the attitude accuracy of the cobot in a single dimension, which is not only inefficient, but also prone to errors and changes, affecting the quality and consistency of the product.
The customer needs to use a 3D scanner to capture the actual position of the target coordinate system (TCP) at the end of the robot in several positions and postures, and compensate and correct the parameters of the robot in the system according to the deviation value from the theoretical point, so as to improve the position accuracy of the robot. 
Traditional Measurement Methods:
01 Wire Pull Method: This method can only compensate for a single dimension, with low accuracy (up to 3-5mm) and poor stability.
02 Commonly used laser trackers: high cost.
Solution: M-Track Robot Path Intelligent Planning and Guidance System
The solution consists of the 3D tracking system i-Tracker and the M-Track software. The customer uses the i-Tracker and M-Track software to obtain the 6D pose of the cobot tool center point (TCP).
01 Create a background point model: Use i-tracker to identify background points and create the correct geodetic datum coordinate system.
02 Create a target model: Create a robot end model and end tool coordinate system in the software.
03 Track the target point and output the coordinates: Call the API to automatically record and output the actual coordinate value of the target point.
04 Compensate and correct the motion parameters of the motion robot: The actual coordinate point and the theoretical coordinate point are input into the compensation software, and the compensation value is automatically obtained, which is used to correct the motion parameters of the robot.
01 Accuracy Guarantee: The i-Tracker tracking system uses binocular stereo vision technology, which can accurately obtain the 6D pose of TCP. When the tracking range is 10At 4m, the accuracy can reach 0049mm；The tracking range is 28At 6m, the accuracy can reach 0067mm；The tracking range is 49At 0m, the accuracy can reach 0089mm, which effectively reduces the pose error of the robot and improves the accuracy of the product.
02 Real-time calibration: M-Track compares the captured pose data with the target data, which can assist engineers to quickly verify and adjust the parameters of the cobot and correct its deviations, further ensuring that the robot performs the task accurately.
03 Efficient and intelligentCompared with traditional calibration methods, M-Track greatly saves time and labor costs, shortens equipment downtime and maintenance time, and provides a more efficient and intelligent calibration solution for robot manufacturing.
With its high-precision, convenient and intelligent features, the M-Track intelligent path planning and guidance system efficiently and completely completes the robot calibration work, fully ensuring the stable and reliable performance of the robot. Robot calibration is an important part of promoting the intelligent upgrading of the production line and improving the efficiency of the production line, and the application of 3D digital technology of Scantech provides a more efficient and intelligent possibility for the control accuracy and stability of the robot, further improves the overall efficiency and quality level of the production line, and promotes the rapid development of the intelligent manufacturing industry.
