Wheel Watcher (servos)

The Wheel Watcher low cost incremental encoder system enables robot builders to quickly add closed loop control.

Both ChA/ChB raw quadrature outputs, and decoded Clock and Direction signals are available.

The clock signal produces 25µs pulses at each transition of ChA or ChB, providing a 4x increase in resolution – 128 clocks per servo rotation – while the direction signal indicates the decoded direction of rotation, making it very easy to add to any microcontroller.

When the WheelWatcher servo encoder is added to a standard size RC servo, it accurately senses direction, distance, velocity, and acceleration.

Installation is easy using the provided hardware and alignment tool.

Applications: Dead reckoning * Odometry * Closed-loop position, velocity, and acceleration control * Stall detection.

Features: Easy installation, Simple interface, 128 clocks per rotation.

Servos and Wheels not included.
