Realizing human-machine collaboration in production and assembly: WIMI holographic development assembly and hand-guided control technology based on brain-computer interface

In modern manufacturing, the continuous innovation and development of technology has brought new possibilities to the production process. In recent years, collaborative robots (Cobots), as a type of compact machine, can not only perform various tasks, but also work collaboratively with human operators to effectively improve production efficiency. In view of the characteristics of small and medium-sized enterprises with small production batches, many and complex tasks, WIMI has developed a breakthrough solution of "assembly and manual control technology based on brain-computer interface", which brings new prospects to the production field.

Traditional production processes often require operators to invest a lot of physical strength and energy, especially in environments with complex tasks and high repeatability, which can easily lead to operator fatigue and increased errors. The introduction of collaborative robots has brought new opportunities to enterprises. Collaborative robots, with their compact size and programmable features, can perform a variety of tasks and can reduce the operator's workload and improve production efficiency. Especially for small and medium-sized enterprises, the introduction of this technology will be an important competitive advantage.

In order to achieve efficient communication and cooperation between humans and collaborative robots, a key issue is how to design appropriate tasks and interaction strategies. In order to solve this problem, WIMI proposed a strategy based on brain-computer interface, which realizes the operator's command control of collaborative robots through brain-computer interface technology.

WIMI’s holographic technology realizes assembly and hand-guided control based on brain-computer interface, playing a key role in brain-computer interface technology. Brain-computer interface (BCI) is a technology that detects brain activity and converts it into instructions that a computer can understand. In this technology, the operator is able to send commands to the collaborative robot through the steady-state visual evoked potential (SSVEP) method. This approach enables operators to switch mission modes without using their hands. In addition, this technology also introduces manual guidance control. By installing a six-component force sensor on the wrist of the collaborative robot, hand-guided control of the collaborative robot is achieved

In the entire process of production assembly, task switching and phase synchronization are crucial. WIMI's brain-computer interface-based assembly and hand-guided control technology divides the collaboration process into independent stages and support stages. In the independent phase, the robot and the operator work in a common scenario to complete a variety of different tasks. Once the operator needs help from the robot, he can switch to the support stage to achieve human-machine collaborative operation. This switching is achieved by the operator sending a command message in the brain-computer interface interface, thereby informing the robot of the intention to switch in advance

In addition, the assembly and hand-guided control technology of WIMI holographic brain-computer interface presents a complete framework in practical applications. Operators can interact with the collaborative robot through an interface. In terms of brain-computer interface related activities, the operator realizes command control of the robot by observing images. These commands are referenced to the robot controller after being collected and processed by the electrodes. On the other hand, with manual guidance control, the operator can guide the robot through sensors on the robot's wrist. The flow of the entire assembly process depends on pre-programmed robot subtasks and real-time commands issued by the operator

The entire process from the operator’s intention to the actual action of the collaborative robot. This process involves multiple links and technologies to ensure that the operator's intentions can be accurately converted into the robot's behavior, thereby achieving efficient human-machine collaborative operation.

Application of brain-computer interface technology (BCI): Brain-computer interface technology is the core of the technical path. In this technology, the operator's brain activity is captured and converted into instructions that the computer can understand, thereby achieving control of the collaborative robot. In WIMI's brain-computer interface-based assembly and hand-guided control technology, the application of brain-computer interface technology achieves switching intentions for different task modes through the steady-state visual evoked potential (SSVEP) method

Data acquisition and processing: The first step in the technical path is the data acquisition and processing of the operator's brain activity. This requires placing electroencephalogram (EEG) electrodes on the operator's head to capture the electrical signals produced by the brain. These electrical signals will be transmitted to a computer for processing to extract information about the operator's intentions

Command generation and delivery: By analyzing the electrical signals generated by the operator's brain, the computer can generate corresponding commands. These commands represent the operator's intention to switch mission modes. These commands need to be passed to the control system of the collaborative robot to control the robot's behavior.

Application of manual guidance control technology: In another branch of this technology field, manual guidance control technology is used to achieve more precise control. The collaborative robot is implemented using a six-component force sensor. The sensor can sense the guidance force of the operator's hand and transmit this information to the robot control system

Control and execution: The commands generated through brain-computer interface technology and the information transmitted by manual guidance control technology are ultimately executed by the robot's control system. The robot switches between different task modes according to the operator's intentions, thereby operating collaboratively in different stages.

Rewritten content: Feedback and synchronization: The final step in the technical display path involves feedback and synchronization. Once the robot performs the corresponding action, feedback information can be passed to the operator to ensure that the operator understands the robot's behavior and status. This helps operators further fine-tune their intent communication, thereby enabling better human-machine collaboration

Every aspect of WIMI holographic technology requires definition of division of labor and implementation to ensure efficient and accurate human-machine collaborative operation. The successful development of this innovative technology has brought new possibilities to modern manufacturing, will improve production efficiency, reduce operator burden, and play an active role in small and medium-sized enterprises

Obviously, WIMI Hologram's "brain-computer interface-based assembly and hand-guided control technology" has brought unprecedented opportunities to small and medium-sized enterprises. By combining brain-computer interface technology and hand-guided control technology, operators can operate at any time Precise control and guidance of the robot can be achieved without using hands. This will greatly improve the efficiency and quality of the production process, reduce the burden on the operator, reduce the error rate, and marks a new era in modern manufacturing. stage.
