Incremental rotary encoders are essential in many robotic vacuum cleaner systems today, contributing critical position information that can be fed back to the system for various uses. This brief explores two incremental rotary encoding solutions—magnetic rotary encoding and optical rotary encoding—and details how magnetic rotary encoding can help improve your design over its optical counterpart. This document delivers side-by-side comparisons of these two technologies where we will observe their power performance and test their susceptibility to external particles in a TI-RSLK kit.
