Robot Auto-Calibration System NexAutoCali

Product Features

Full-Parameter Calibration

Full-parameter calibration is currently the optimal solution for high-fidelity alignment between the robot's theoretical model and its physical entity, capable of exploiting the precision limits of the equipment itself.

Taking a flexible arm test as an example, after full-parameter calibration by the Nabote Auto-Calibration System, TCP accuracy was improved from 3 mm to 0.5 mm, a 500% increase.

Fast

This calibration system streamlines operating logic, reducing the difficulty of training and use;

The quick-mount structure design completes hardware and software environment preparation in just 5 minutes;

The optimized calibration process delivers a standard 50-point calibration in less than 5 minutes.

Visualized

A variety of icons display real-time coordinate positions, trajectory positions, multi-round test repeatability errors and other characteristics, greatly improving ease of use.

Fully Automatic

Leveraging Nabote's drive-control advantages, the entire workflow — from automatic measurement point planning, automatic running, to automatic measurement — is fully automated, dramatically improving ease of use and reliability.

High Integration

The system integrates measurement point planning, trajectory planning, motion control, and robot parameter reading/writing into one. A single software can complete both calibration and measurement tasks.

Full-Featured

Built-in robot calibration modules support reduction-ratio calibration, zero-point calibration, link-length calibration, and full-parameter calibration; Built-in 14 robot performance metric test modules, fully compliant with Chinese national standard GB/T 12642—2013 / ISO9283:1998. Version-independent, providing a full feature package.

High Compatibility with Robots / Trackers

Compatible with seven-axis collaborative, six-axis industrial, and six-axis collaborative models — the major industrial application models — and customized model adaptation can be provided according to user needs. Multiple laser tracker models from API and Zhongtu Instruments have also been adapted.

High Measurement Accuracy

Through the combined use of high-precision laser trackers from API, Zhongtu Instruments and others, the system can accurately measure the actual errors of the robot body, improving the accuracy error of point-around motion by 3× before and after calibration.

Main Functions

Highly Integrated All-in-One System

This system integrates laser tracker measurement, robot motion control, automatic calibration/measurement point planning, fully automatic control of calibration/test processes, and algorithm computation. Combined with the laser tracker's lightweight design and built-in power supply, built-in Wi-Fi functions, it enables rapid operation, greatly improving work efficiency and lowering the entry barrier.

High Flexibility

On top of easy operation, the system allows free configuration of the number of calibration points, number of tests, payload, speed, dwell time, etc., to meet on-site test requirements.

Motion Control Module

The robot position planning and motion control module is integrated. No programming by the user is required during the test — all operations can be completed in the laser tracker calibration system, reducing the user entry barrier and commissioning cycle, and greatly improving test stability and efficiency.

Measurement Point Generation and Test Environment Management

The system can automatically connect to the robot, read robot parameter information, and automatically plan the measurement point positions required for calibration. Meanwhile, the system has a built-in test environment management module that can uniformly manage robot information, control system information, test environment, test instrument information, payload information, and speed information. Test reports support exporting the test environment.
