Gasgoo Munich- Baolong Automotive recently secured a project designation for a robot rotary joint encoder. The designated product is a co-located dual-encoder, single-turn absolute inductive encoder. It employs non-contact electromagnetic coupling to achieve synchronous, high-precision detection at both the motor and output ends.

The encoder boasts three core features: interference resistance, high-temperature tolerance, and high precision. It is naturally immune to stray magnetic fields and operates stably across a wide temperature range from -40°C to 125°C. On precision, a multi-pole design achieves a maximum resolution of 19-bit.
In the field of embodied intelligence perception, Baolong Automotive leverages a foundation of hundreds of millions of automotive-grade sensors. Through inductive technology innovation, it has boosted robot joint repeatability to ±10 arcsec and slashed dynamic response times to under 1ms. Addressing challenges like strong magnetic interference, tight spaces, and the need for full closed-loop precision in humanoid robot joints, the solution offers a mass-producible, automotive-grade option.
The encoder also offers 100% magnetic immunity, full environmental robustness, ultra-thin integration, and high reliability. With IP67-rated physical protection, signal attenuation remains below 0.5% in environments with oil, dust, or vibration. Its thickness is just one-third that of traditional solutions, reducing axial space and enabling integration into high-power-density joints. Key components are automotive-grade, ensuring consistency in mass production.
Baolong Automotive says it will continue to deepen its presence in the embodied intelligence sector. Leveraging advanced technology and production capabilities, the company aims to drive the industry's rapid advancement.
