The wide range of motion required by humanoid robots, from upper limbs and waist to lower limbs, drives the need for three main types of joint modules: planetary, harmonic, and linear. Modern joint modules adopt a highly integrated design, combining core components like reducers, motors, drivers, and encoders into a single unit. Leveraging all-hardware FPGA […]

I. Overview and Classification of Absolute EncodersAn absolute encoder is a sensor that directly outputs the shaft’s angular position information. Its core characteristics are position uniqueness and power-off memory function. Even if the shaft continues to rotate after a system power loss, the encoder can immediately feedback the current absolute position information upon power-up without requiring a homing

I. Standard Cored Motor The rotor of a standard DC motor is laminated from silicon steel sheets, and the windings are wound around an iron core. It has high inertia, high inductance, and a relatively slow response speed. 1. Requirements for Position Sensing: 2. Implementation Methods:Position sensing in standard motors typically uses physical sensors mounted directly on

BiSS and SPI are two common serial communication protocols used in industry, particularly in motor encoders and sensors. Although they may appear similar externally, there are key differences in their design goals, operating principles, and characteristics. In short: Below, we will compare them in detail across several parameters. General Comparison Characteristic BiSS Protocol SPI Protocol

As the core driving component of a robotic arm, the performance of a robotic joint directly determines the precision, reliability, and service life of the entire machine. This article details the full-process testing solution for robotic joint systems, from PCB-level testing to the aging tests of fully assembled units. It covers the verification of multiple

  1. Construction of Magnetic Encoders Magnetic encoders detect rotational position by measuring magnetic field variations and converting them into electrical signals. A basic configuration consists of a permanent magnet and magnetic sensing IC. The magnet is mounted on a rotating body (e.g., motor shaft), while the sensor IC is positioned on a PCB within the magnet’s field

A robotic joint module is a standardized mechanical unit that integrates key subsystems—including motors, reducers, encoders, controllers/drivers, and structural components—into a compact assembly. Designed to output rotational or linear motion, it drives robotic limbs while enabling closed-loop control and intelligent communication. As the fundamental functional unit for robotic motion control, it delivers precision and efficiency

In IoT applications, wireless technologies can b categorized into Wide Area Networks (WAN) and Local Area Networks (LAN).   Wide Area Networks (WAN) Examples: 2G, 3G, 4G, 5G, NB-IoT.   – Characteristics:    – Operate on licensed frequency bands (government-regulated, requiring permits).    – Ideal for long-range, high-bandwidth applications (e.g., smart cities, asset tracking).   Local Area

The global manufacturing sector is undergoing a transformative wave driven by innovation and energy efficiency, with automation, digitalization, and flexible intelligent equipment at its core. While traditional industrial robots excel in speed, precision, and heavy payloads, they face limitations in adapting to dynamic production lines, reducing operational complexity, and enhancing productivity.
