オドメトリ用センサとしてのダイナモの出力信号評価

抄録

We are studying the use of a dynamo in a wheel-type moving body that has a steering control device and can be driven manually and can be used not only for power generation but also as a sensor for odometry. We manufactured an angle accuracy measuring device by the counter method, and the accuracy of the dynamo was measured. It was shown that the error on the road was less than 3mm, assuming that the wheel diameter was 100mm in the range of 0.2rps to 1rps.Since the hub dynamo used this time has 16 poles, the resolution for measuring the amount of movement on the road surface is about 20 mm. From the above, it was shown that the hub dynamo can be sufficiently used as a sensor for odometry.
