Technical Analysis Conntek KTM5900 vs Novosense NSM350x: China’s Next-Gen Off-Axis Magnetic Encoder ICs OTV Sensing · July 31, 2026 · 8 min read The robotics industry faces a persistent engineering challenge: how to route cables through hollow joints while maintaining high-precision position feedback in an extremely compact space. Two Chinese semiconductor companies have recently stepped

electronica China 2026: Embodied AI Is Redrawing the Magnetic Sensor Map July 1, 2026 · Shanghai New International Expo Centre · OTV Sensing on the ground Walking the halls at electronica China this year, one thing was impossible to miss: embodied AI has arrived, and it runs on magnetic sensors. Automotive and industrial automation still

Is Your Encoder Accuracy Still There When Temperature Rises 10°C? Magnetic encoders are prized for dust immunity, oil resistance, and maintenance-free operation. But there’s a silent killer that’s often overlooked — temperature. The magnetic field strength of an encoder ring drifts with temperature. When a robot joint goes from cold start to full load, with

Maxwell: Translating God’s Language with Mathematics “Maxwell’s work is the most profound and the most fruitful that physics has experienced since the time of Newton.” — Albert Einstein If Newton translated the language of “force,” Maxwell translated the language of “fields.” Electricity and magnetism, light and waves, energy and spacetime — under his pen, they

The Most “Divinely Inspired” Equation in Mathematics— And You Use It Every Single Day OTV Precision Sensing | Technical Blog Take a look at this equation. Don’t worry — by the end of this article, you will understand exactly what it does and why it’s beautiful. FOURIER TRANSFORM F(ω) = ∫-∞∞ f(t) · e-iωt dt

Shipping a humanoid robot is not like shipping a laptop. Before a single unit leaves the factory, it must pass through a gauntlet of test stations — each designed to catch a specific class of failure before it reaches the customer. Drawing on a real production test specification for a full-scale humanoid robot, this article

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
