To Your Basket Ordering Information Part Number: R238-WW01-KIT Price: $49.95 Weight: 0.15 lbs This WW-01 WheelWatcher Encoder Kit by Nubotics includes parts to assemble two incremental quadrature encoder systems that attach to standard RC servos. The incremental encoder system works with standard servos and standard injection-molded wheels. The kit also includes an alignment tool and instruction booklet.

More Details:

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.

The WW-01 WheelWatcher encoder is designed to work with the plastic molded wheels that we sell. The kit can also be adapted to work with servo horns and other mechanisms by adding a CS-040-01 spacer.

The WW-01 WheelWatcher encoder will NOT work with DC motors such as the GM8 series. If you are using gearhead motors, consider using a WW-02 WheelWatcher encoder kit.

Wheels and servos sold separately.

This kit is designed by Nubotics and distributed by Acroname Inc.
