Wheel Watcher Rotation Encoder for GM2/3/8/9

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:

• 32 stripe codewheel
• Hardware quadrature decode with 4x multiply for 128 clocks per rotation
• Mates with GMPW / SW wheels

The Nubotics documentation contains all assembly & application notes to successfully implement your Wheel Watcher.

This kit contains a single preassembled sensor board, codewheel, and wiring kit. Large plastic wheel and gearmotor not included.

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