A robot is a machine device that automatically performs tasks. It can be commanded by humans, run pre-programmed procedures, or act according to principles established using artificial intelligence technology. Its task is to assist or replace human work, such as in manufacturing, construction, or hazardous jobs. It is a product of advanced integrated cybernetics, mechatronics, computers, materials science, and bionics. It has important applications in industry, medicine, agriculture, construction, and even the military. Based on their application environments, Chinese robotics experts classify robots into two main categories: industrial robots and special-purpose robots. Industrial robots are multi-jointed manipulators or multi-degree-of-freedom robots designed for industrial applications. Special-purpose robots, on the other hand, are advanced robots used outside of manufacturing and serving humanity. However, existing robot controllers lack devices that facilitate the installation of different types or functional control components and the easy location or maintenance of electrical control components. Some robot controllers also lack devices that facilitate the quick connection of various functional housing wiring connectors, failing to meet practical needs.
1 Design of a dedicated robot controller
The proposed robot-specific controller includes a control box, a connector, a transfer box, and an equipment box. The control box is connected to the distribution box, and the distribution box is connected to the transfer box via a connector sleeve. The connector is located at the left end of the distribution box.
As a preferred technical solution of this design, the connector sleeve is provided with threads and guide grooves. The threads are fine-pitch threads, and the guide grooves are located on both sides of the threads. A wear-resistant coating is provided inside the guide grooves, and a limiting post is provided at the end of the wear-resistant coating. A clamping assembly is provided on the transfer box. A rust-proof coating is provided inside the equipment box, a flame-retardant coating is provided on the rust-proof coating, and a wrapping layer is provided on the flame-retardant coating. The wrapping layer is a polymer film. In field use, the operator first installs the entire device in a suitable position and then fixes the entire device. Next, different types or functional control components and easily locateable or repairable electrical control components are installed in the control box, transfer box, equipment box, and distribution box, respectively. Finally, the various functional box wire connectors are quickly connected through the connector, connector sleeve, and clamping assembly to install the robot control components.
Compared with existing technologies, the advantages of this design are: by setting up control boxes, transfer boxes, equipment boxes, and distribution boxes, it helps to provide installation areas for different types or functions of control components and facilitates the location or maintenance of electrical control components. The inclusion of connectors, fittings, and clamping assemblies facilitates quick connection of wire connectors for various functions within the enclosures, and the design is simple in structure, easy to operate, and economical.

2 Application Examples
2.1 Basic Information
This project develops a humanoid intelligent fighting robot designed with the theme of the Heisei warriors of the capital city during the mid-Northern Wei Dynasty. It's a novel robot combining humanoid design with motion-sensing technology, fully utilizing and leveraging the characteristics and advantages of humanoid robots to achieve human-robot interaction. The technological foundation for this functionality lies in its ingenious and unique mechanical structure design and excellent motion control. For the robot, the key lies in the optimized design of its mechanical structure and drive unit, with its main function being to perform intense fighting demonstrations. Based on the design content and requirements, the robot design scheme was determined. Servo motors and servo motor control boards are used to achieve the fighting action performance. Following instructions from a motion-sensing simulator, a new type of humanoid robot, "Heisei Warrior," was designed with human-like functions and simulated fighting movements. Referencing human anatomy, it performs basic movements: forward and backward movement, sideways movement, turning left and right, low-profile walking and high-profile walking to evade attacks, and simple fighting actions. Its walking frequency is two steps per second, and it exhibits flexible hand and foot movements, turning, and head movements, as well as voice functionality. Through voice recognition technology, simple human-robot dialogue can be conducted with "Heisei Warrior." Its feet have a triangular structure, which provides strong pressure resistance and stability.
2.2 Feature Description
1) Motion performance. The robot should have good mobility and flexibility, and be able to complete forward, backward, and turning movements smoothly and quickly. In addition, the stability of the robot's movement should be ensured to avoid tipping over.
2) Robustness. In terms of mechanical design, the robot should have good robustness. During the robot's dance movements or movement, various connectors should not loosen or fall off.
3) Reliability. Due to the large number of components in the robot control system, there is interference from various sources, which places certain demands on the hardware circuitry and software programming design of the robot control system.
4) Maintainability. Maintainability is crucial for any device. Maintenance should include both hardware and software maintenance. Therefore, the hardware structure design should consider ease of installation, disassembly, debugging, and testing; the software should adopt a modular structure design to facilitate testing and upgrades.
5) Economic efficiency. Selecting a suitable control scheme and cost-effective functional components can both meet the system's functional requirements and save costs. From the above analysis, it can be seen that, given the limitations of robot size and weight, the key to designing a robot with the above functions lies in employing high integration and miniaturization technologies and solving structural optimization problems.
6) Popularize the technology. Create detailed tutorials, sell individual parts, and simplify the relevant technologies to make them easier to learn and popularize.
2.3 Scheme Introduction
Currently, research on humanoid robots both domestically and internationally is conducted independently, without any combined research. The Heijo Samurai fighting robot is a fighting robot that combines humanoid robotics with motion-sensing technology. Its exterior is made of 3D-printed materials, and the body is constructed from aluminum alloy plates, stainless steel sheets, servos, controllers, and their support structures. The design of the new robot "Samurai" fully utilizes and leverages the characteristics and advantages of humanoid robotics and motion-sensing technology. The technological foundation for this functionality lies in its ingenious and unique mechanical structure design and excellent controller drive. Humanoid mechanical structures are applied in the design. The Heijo Samurai fighting robot has three operating modes: automatic, remote control, and human-robot interaction. In automatic mode, pre-programmed motion sequences are sent to the robot via the controller, allowing it to perform autonomously to music. In remote control mode, users send commands to the robot via a handle, enabling it to perform corresponding actions, including high, medium, and low-profile forward, backward, and turning movements. In interactive mode, motion-sensing technology is used for seamless human-robot interaction. These three modes can be switched freely according to needs, offering convenience and enjoyment.
From a technical perspective, this interactive method differs from the current mainstream button (keyboard, mouse, remote control, etc.) and touch (tablet, smartphone, etc.) interaction methods. Motion-sensing interaction technology can be seen in many science fiction films, such as the classic scene in *Minority Report*. This technology can bring entirely new experiences and accomplish what other technologies cannot. Motion-sensing technology allows robots to interact naturally with surrounding devices or environments, a method that is clearly more advantageous than button and touch interaction. However, its characteristics are not intended to replace the former two. It is easier for people to use, accept, and master, which is conducive to its widespread adoption. This necessitates higher requirements for motion-sensing interaction technology, demanding greater accuracy and intelligence.
