Making a high resolution(20bit more) optical encoder with interpolation. SensorLab.
Hello, this is Sensor Lab.
I will introduce you to a high-resolution optical encoder(sensor) for robots.
-Design a disk and a reticle for the optical encoder
- Make analog signals (Sine & Cosine wave)
- high resolution Interpolation
- Compare the low resolution encoder
This encoder is for the servo motor, robot and etc.
This sensor is mounted on the output shaft of a collaborative robot reducer to sense the final position and is suitable for shock detection, teaching, etc.
As you can see, it is a magnetic sensor used in combination with gears.
It is possible to use it in combination with gears or with a magnetic scale as shown in the following application example, but in this video, it is recommended to use it in combination with gears.
Thank you

Very good! Thanks!
I'm glad you liked it.
Excellent!
I'm glad you enjoyed it.
The basic idea is good, but not novel. You will not get anywhere near 20-bit performance this way. Measuring any physical quantity (except time) to within one part in a million hardly ever happens in practice. 20 bits is the equivalent of a breath of air compared to the weight of a car. Consider that the placement of the slots will need to be accurate to a millionth of a circle, (about 1 second of arc) or you will get missing codes. You will not get a sine wave so distortion-free that you can interpolate it to thousands of different levels. You will also need to deal with the effects of physical optics. As an optical aperture closes, the light transmitted in a given geometric path becomes non-monotonic due to optical diffraction. Your light detector will have shot noise that will become significant as the rotation speed increases. Stray light needs to be eliminated. I suggest that you try to build a 20-bit rotation encoder, put it on the same shaft as a commercial 20-bit encoder (like one from Renishaw) and present the results of your comparison in a follow-up video. If you can get the first 14 or 15 bits to agree, you will have done admirably.
Thank you for watching and commenting. This video basically explains the principle of making a high-resolution encoder as you mentioned. The encoder shown now is an encoder with 24-bit resolution by interpolating 2048ppr + 13bit. In order to compensate for the optical distortion you mentioned, an interpolator with a built-in real-time correction function was used. (The interpolator uses the function shown in the video.) Next, I will explain by making a video demonstrating an encoder with 20bit or more using a photo IC and a high resolution interpolator. I will demonstrate and explain the part where the optical signal is distorted and how to compensate for it. Your comments were a great help in making the video.
Good information. Thanks.
Thanks for the feedback!

마그넷 고정자의 폴피치를 홀센서 파형으로 변환하고 체배하여 구동하는 개념 같은데요 ? 스케일이 없다는 말은 과장 아닌지요 ? 방송 감사합니다.👍👍
시청해주셔서 감사드립니다. 말씀하신데로 리니어모터의 고정자 영구자석의 자속밀도를 센싱하는 방식입니다. 스케일이 없다라는 표현은 리니어모터에서 스케일을 별도로 부착하지 않는다는 의미입니다. 정확하게 의미하면 영구자석을 스케일로 사용하는 것이 맞습니다. 과장이라면 과장일 수도 있지만 여러회사에서 이와유사한 방식에 대해서 통상적으로 Scale-less 등의 표현을 씁니다. 예를 들어 센서리스 콘트롤도 모터의 고정자를 스케일로 사용하고 가동자에서 인던턴스와 backemf 변화등으로 위치를 센싱하지만 별도의 센서가 없으니 센서리스라는 표현을 널리 사용하는 것과 같은 경우라고 이해해주시면 좋을 것 같습니다.

시청해주셔서 감사드립니다. 보내주신 영상은 TM 로봇이라는 대만업체의 협동 로봇을 이용한 제품입니다. 그리고 로봇 끝단에 robotiq라는 손(그리퍼)를 장착하였습니다. 문의주신 내용인 협동 로봇 자체를 만들고자하시는 건지 아니면 협동로봇을 구매하여 요리를 하는 로봇으로 응용하고 싶다는 건지에 따라 차이가 큽니다. 일단 로봇 자체를 개발하시고 싶다라고하면 사실 굉장히 방대한 내용입니다. 유니버셜로봇, 레인보우로봇이나 두산로봇에서 주력으로 생산하는 제품이 협동로봇입니다. AI, SW, 서보제어, 감속기, 모터, 센서 등 다양한 분야의 사람들이 모여서 만드는 것이니까요. 제 영상과 같이 HW 기반의 액츄에이터(서보, 감속기, 센서)부분이 궁금하시다고하면 기본적으로 Universal robot을 분해한 영상들이 많습니다. th-cam.com/video/I1MOxx0Q1D0/w-d-xo.html th-cam.com/video/oje2ucwe3vI/w-d-xo.html 로봇 제어에 관련된 부분이 궁금하시면 다이나믹스를 풀거나 지능제어에 대해서 공부하시면 좋을 것 같습니다. th-cam.com/video/wO8zpXRBlFw/w-d-xo.html 방대한 내용의 질문이라 답이 되었으면 좋겠습니다.
