You could have designed state of the art positional encoding

With https://huggingface.co/Robonine team we recently verified the rotational speed of the Feetech STS3250 servo motor (12 V, 50 kg·cm torque, magnetic encoder) to compare measured performance with the official specification. According to the datasheet: - Rated speed: 0.133 s per 60° Calculation: - 0.133 s × 6 = 0.798 s per full rotation - 1 / 0.798 = 1.253 revolutions per second - 1.253 × 60 = 75.2 RPM This confirms the official specification of approximately 75 RPM at 12 V under no load. Our measurement: - Encoder output: 5,300 values per second - Encoder resolution: 4,096 counts per revolution Calculation: - Revolutions per second = 5,300 ÷ 4,096 = 1.294 rev/s - RPM = 1.294 × 60 = 77.6 RPM Result: The measured value differs by only about 2–3% from the datasheet specification, confirming that the STS3250 performs very close to its rated no-load speed. This close agreement validates both the servo’s performance and our measurement approach.
