Robot AI Module High-Speed Signal Transmission Solution: Design Guide for Extremely Thin Coaxial Cable Bundles

In robotic systems, the signal transmission quality of AI modules (visual, sensor, communication units, etc.) directly affects the system's operational stability and task execution accuracy. The extremely fine coaxial cable (Micro Coaxial Cable), with its small diameter, high shielding properties, and high-speed transmission capabilities, has become the ideal choice for high-density wiring and high-speed data links within robots. During the design and installation process, rational wiring, shielding, and impedance matching are crucial steps to ensure stable and reliable signal transmission.

I. Characteristics and Advantages of Ultra-Fine Coaxial Beam

Extremely fine coaxial cables are composed of an inner conductor, insulation layer, shielding layer, and outer sheath, and possess excellent electromagnetic interference resistance and precise impedance control. Their small diameter and high flexibility make them particularly suitable for applications in robot interior spaces with limited space, while also supporting high-speed signal transmission without significant attenuation or distortion. Compared to traditional wiring or ordinary cables, extremely fine coaxial cables can maintain signal integrity in high-frequency, high-precision scenarios, providing a reliable guarantee for the performance of robot AI modules.

Application scenarios in robot AI modules

In visual systems, data transmission between cameras and main control chips usually employs high-speed interfaces such as MIPI-CSI/DSI, which have extremely high requirements for signal integrity. Sensor modules like IMU, LiDAR, or rangefinders also require stable high-speed data collection and transmission. The radio frequency signal wiring of wireless communication modules depends on cables with low loss and high shielding to ensure data reliability. Additionally, high-speed data links between different boards or modules also need good impedance matching and anti-interference capability to ensure stable operation of robots in complex environments.

Three, key points for wiring design and optimization

Reasonable wiring design is the key to ensuring signal stability. Firstly, it is necessary to shorten the transmission path as much as possible and avoid unnecessary bends, while ensuring that the bending radius is greater than the allowable value of the cable. The shielding layer must be continuously connected to the ground to prevent noise and crosstalk. The impedance matching between the cable and the connector needs to be strictly controlled to avoid signal reflection. Terminal processing requires precise stripping and crimping to reduce losses caused by poor craftsmanship. For robot motion joints or vibration environments, flexible sheaths can be added, line cards can be used for fixation, and signal testing should be carried out after wiring to ensure that the waveform, frequency, and anti-interference performance meet expectations. Through these measures, signal distortion, interference, or unstable joints can be effectively reduced, enhancing the reliability and lifespan of the robot system.

In the robot AI module, extremely fine coaxial cable bundles not only solve the problem of space constraints but also ensure stable transmission of high-speed and high-precision signals. Through reasonable design of routing, shielding structure, impedance matching, and terminal processing, combined with fixed and testing measures, it can significantly improve the reliability and long-term performance of the system, providing a solid signal guarantee for high-end robot applications.
