Dual Wheel Watcher Rotation Encoder Kit

This package essentially is a twin-pack of the GMWW02 encoder kit, with an encoder alignment tool thrown in!

This "Incremental quadrature encoder system" is specially designed by Nubotics to retrofit to our GM2, GM3, GM8 or GM9 gear motor. If you need to control a robot for dead reckoning, tracking odometry (distance travelled), stalled motor, or closing the feedback loop for position/velocity/acceleration, this is your solution.

It features:

• Two 32 stripe codewheel
• Two Hardware quadrature decode with 4x multiply for 128 clocks per rotation
• Wiring package
• Mates with Solarbotics' GMPW Wheels

Note: The GM2 & GM3 need GMWWS spacer for proper operation, due to their longer output shafts. So unless if you're comfortable in cutting down the shafts on your own, these are the ideal solution.
