The WW-01 WheelWatcher incremental encoder system attaches to the outside of a standard RC servo, and utilizes an adhesive-backed reflective codewheel, designed for standard injection-molded robot wheels, to determine wheel rotation rate and distance travelled. It produces standard ChA/ChB raw quadrature outputs, as well as decoded clock and direction signals. The clock signal produces 25 us pulses at each transition of ChA or ChB, providing a 4x increase in resolution - 128 clocks per servo rotation. The direction signal indicates the decoded direction of rotation. Wheels and servos sold separately.
