Boe-Bot Digital Encoder Kit

The Boe-Bot® Robot Digital Encoder kit answers a long-standing customer request for position feedback used to improve dead-reckoning, solve mazes, contests and map paths of travel. The infrared reflective sensors mount next to the Boe-Bot Robot’s wheel to count cycles using the wheel holes. This is an add-on kit for the Parallax Boe-Bot Full Kit, which includes the newer wheels required for the Digital Encoders.

The real value of the Digital Encoder kit isn't in the hardware, though. It lies with the extensive application notes published to get you started with the kit. The "Applying Digital Encoders" document and the Boe-dar software program are two examples of how the Digital Encoders can be used with the Boe-Bot Robot. Follow the Boe-dar link to see how you can use these encoders with our RF modules to map the travel of your Boe-Bot Robot.
