During running, jumping, and obstacle crossing, quadruped robot joints undergo high-frequency impact and severe vibration; as the core joint position feedback device, the encoder directly determines gait stability and motion reliability.
- Strong impact vibration on landing easily causes angle signal jitter
- Compact internal joint space imposes strict demands on device size
- Needs to read multi-turn angle directly at power-on, suiting complex gait control
- Mass production imposes high demands on assembly compatibility and cost control
ESSTMAGS offersEAS-081 (optional EAS-081FS functional safety version), encoder kit dedicated to quadruped robot joints, delivered as a set with TMR magnetic sensor IC (BBT-A903) + magnet, suiting robot joints with an outer diameter of 34-48mm;
Supports mechanical limited multi-turn detection; the customer only needs to complete PCB integration, with full mounting guidance to shorten R&D cycles.
