Gear tooth sensor vs. Optical Encoders
I was wondering if anyone has tried using the gear tooth sensors from the KOP, and knows how well they work? I've used optical encoders before, and know those work well. So how does the gear tooth sensor compare, in terms of accuracy? If it matters, I'm planning on using one of these two sensors for robot speed and speed our launcher system is spinning.
Also, can the gear tooth sensors sense the direction of the spin, or just velocity? And...while I'm at it...how does the accelerometer compare to these when trying to see robot velocity? |
