ABB has introduced various features to its GoFa series cobots to enhance their accuracy, operational efficiency, and applicability.
ABB's new features in the GoFa series of cobots are unlike any other advancements in the market. With the new Ultra Accuracy feature, ABB claims that the path accuracy within the GoFa series will be increased tenfold. Users will also benefit from a full range of motion, as GoFa cobots offer full 6D motion across the entire workspace.
In many cobot applications, the tasks must be simple, require minimal weight, or be geared towards entertainment scenarios, such as a robot fetching alcoholic beverages at automation showcases. ABB aims to enhance cobots' accuracy to meet the demands of applications where precise positioning is crucial, such as gluing and sealing in consumer electronics production, laser welding, composite material layering in aerospace manufacturing, and precision laser fabrication processes.

How does the Ultra Accuracy Feature Work?
A statement such as a tenfold increase in path accuracy might make many potential users wonder if it's too good to be true or sprout curiosity on exactly how it works.
The Ultra Accuracy feature enhances the cobot by upgrading components and algorithms, as well as the technology behind the software. It incorporates high-resolution sensors that provide real-time feedback on the cobot’s position and movements. These sensors use advanced algorithms to adjust the cobot’s path precisely, ensuring it follows the intended trajectory with extreme precision.
The cobots are also equipped with improved actuators that execute precise movements as directed by the algorithms, minimizing deviations from the desired path. Additionally, advanced calibration techniques reduce errors and ensure consistent accuracy across different tasks and environments. This combination of technologies allows the GoFa cobots to achieve a path accuracy of 0.03 mm, making them ideal for applications that require high precision and rigorous safety standards.

GoFa Cobots Vs. Gantry Systems
The GoFA cobots from ABB Robotics offer several key advantages over traditional 2D gantry systems. They can move in six dimensions (X, Y, and Z axes plus roll, pitch, and yaw) rather than only two dimensions.
Upon delivery, GoFa cobots are ready to operate with full 6D motion without extra calibration. This reduces setup time and cost, making them efficient and more easily integrated into existing workflows. The ability to move in six dimensions means these cobots can handle a wider variety of tasks, from simple pick-and-place operations to more intricate assembly processes. The 6D feature makes the GoFa cobots a more adaptable and efficient solution for modern manufacturing needs.
Offline Cobot Programming
When GoFa cobots are equipped with the Ultra Accuracy feature and used with ABB’s RobotStudio software, users can program the cobots’ tasks and movements in a virtual environment. This combination also ensures the simulations are incredibly close to real-world performance, with a 99% match. This high level of accuracy means that what you see throughout the simulation is almost precisely what you will get. Because the simulation is so accurate, there is no need for additional adjustments once the cobot is deployed, saving time and ensuring that implementation is both precise and efficient.
The Ultra Accuracy feature is an optional upgrade that can be integrated into existing GoFa cobots, enhancing their precision and performance.
