Stereoscopic vision and intelligent perception: the visual brain of the UBTECH Walker S2 industrial robot
One of the pillars of the UBTECH Walker S2 is its ability to perceive its environment with extreme precision, thanks to binocular RGB stereoscopic vision integrated into its head. This technology, directly inspired by human vision, allows the real-time reconstruction of a depth field for finer manipulation and interaction with surrounding objects in an industrial setting.
Unlike other robots equipped with costly hardware depth sensors, the Walker S2 relies on a sophisticated software solution developed in-house. This involves the use of deep learning algorithms that constantly recalculate spatial geometry and estimate depth with great accuracy. This technical choice is strategic: it reduces hardware cost and complexity while offering scalable adaptability through software updates.
This approach allows the robot to recognize and differentiate a wide variety of objects with nuances, essential in processes such as automotive assembly, logistics sorting, or automated maintenance. For example, during autonomous battery replacement, stereoscopic vision detects the charge status of the modules and adjusts the grip for perfect alignment.
This high perception fidelity thus optimizes operational safety, reduces human errors, and opens the way for integrating robots into non-standardized production lines where environmental conditions vary.
As an example, an electronics factory using the Walker S2 reported a 25% reduction in component placement errors thanks to its visual system, thereby enhancing overall manufacturing quality.
Co-Agent and collective intelligence: the future of industrial automation with the Walker S2
Robotics is no longer limited to the isolated execution of tasks. The UBTECH Walker S2 notably integrates the Co-Agent system, a next-generation collective intelligence for industrial humanoid robots. This smart technology coordinates actions, optimizes productivity, and manages complex interactions in automated production environments.
Co-Agent enables robots to collaborate in swarms, sharing data and feedback to adapt to variations in the industrial process. This innovation not only facilitates the synchronization of operations such as screwing, adhesive application, or software configuration but also increases the overall resilience of the production chain.
Replacing hardware depth sensors with pure RGB vision, the Walker S2 maximizes its potential thanks to embedded computing power, making the platform more flexible and less costly. This intensification of software capabilities enables quick updates and adaptation to new tasks without hardware modifications.
In a major automotive factory in Shanghai, Co-Agent increased coordination among the Walker S2 robot fleet, reducing downtime by 18% and improving the quality of work on body panels thanks to better task distribution.
This advancement marks a milestone in industrial transformation towards connected factories, where advanced robotics fosters increased synergy between machines and humans.
