It features 20 slots or grids distributed around the disc, allowing a sensor to detect rotational movement and generate pulses that can be used to estimate motor speed and wheel rotation.\u003cbr\u003eThis encoder disc is useful for robotics projects that require motor feedback for speed measurement, distance estimation, and movement control. When paired with an appropriate infrared or optical sensor module, it enables a microcontroller such as an Arduino, ESP32, or Raspberry Pi to count pulses generated as the disc rotates.\u003cbr\u003eThe 20-grid design provides multiple detection points per revolution, making it suitable for basic feedback systems in educational robots, line-following robots, and small autonomous vehicles. By counting the detected pulses over time, a controller can estimate rotational speed and, with suitable wheel and gearbox calibration, calculate approximate travel distance.\u003cbr\u003eDesigned for use with compatible BO motors and encoder assemblies, this disc is a practical component for robotics experiments, motor monitoring, and closed-loop control projects. The disc dimensions, shaft mounting arrangement, and sensor compatibility should be checked before installation to ensure proper alignment and reliable pulse detection.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cp\u003e20-slot or 20-grid encoder disc design\u003cbr\u003eDesigned for compatible BO motor encoder assemblies\u003cbr\u003eEnables motor rotation and speed measurement with a suitable sensor\u003cbr\u003eSupports pulse counting for rotational feedback\u003cbr\u003eUseful for distance estimation when combined with wheel calibration\u003cbr\u003eSuitable for Arduino, ESP32, and other compatible controller projects\u003cbr\u003eIdeal for educational robotics and DIY automation\u003cbr\u003eCan support closed-loop motor speed control\u003cbr\u003eLightweight design for small robotic platforms\u003cbr\u003eRequires a compatible optical or infrared sensor for pulse detection\u003c\/p\u003e","brand":"Roboracter","offers":[{"title":"Default Title","offer_id":48127362990134,"sku":null,"price":19.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0715\/0731\/2694\/files\/BlackRadialSlottedMechanicalDisc.png?v=1792095170","url":"https:\/\/roboracter.in\/products\/20-grids-disc-wheel-encoder-for-bo-motor-pack-of-4","provider":"Roboracter","version":"1.0","type":"link"}
