In the field of medical robotics, encoders are often misunderstood as devices that "only provide feedback, not control." Technically, this statement is correct. But logically, it overlooks the most fundamental premise of any closed‑loop control system: without accurate feedback, there is no effectiv
In precision motion control, there is one fundamental question every machine must answer: "Where am I right now?" An absolute encoder answers this question instantly, uniquely, and permanently — even after a power loss.Unlike an incremental encoder, which only reports changes in position and require
