I don't know what you're so upset about Hmm let's see... 1. you're shamelessly advertising your own product 2. you pretend to be someone you're not 3. you say that step motors and servos suck, just because you'd have to spend more time to get them to work the way they should. However you state that...

One of the reasons it's no good (out of several) is because of the slight lag between real-time and the time that the PC has finished processing the frame that seems kind of counter intuitive - the software can detect motion and estimate lead but it cannot track a small dot? Hmmm I found processing...

..it would be a lot easier to mount an IR laser on the gun and use the camera to track it. nope. I've already played with that method. One of the reasons it's no good (out of several) is because of the slight lag between real-time and the time that the PC has finished processing the frame. It is fi...

I doubt any serious attempt to make a sentry gun with steppers would fail because of the use of steppers. Near as I can tell, servos are almost always used in low power applications. For applications that require serious power from the motor(s), steppers seem to dominate. The reasons I mentioned se...

Like I said before, stupid in is stupid out regardless of the hardware. There is a fundamental problem, and then several other smaller problems with steppers. I know what you're saying but I'll believe it when I see it. As common as it is for people to think steppers are the way to go I'm betting t...

I've seen it. It is just as bad as the others. I've seen them all and this one is clearly the most advanced by a wide margin. Forgive me sensei I forgot that you're not advertising your own product You're making several assumptions to come to that conclusion. You know what they say about assuming.....

That's why I suggested a microcontroler.... I've used code from the link I posted earlier in the thread and it works... you just send the absolute position through serial and the motor gets there... you might as well use ramp function that deals with inertia You still don't get the fundamental prob...

In the real world, particularly when precision is required, you don't tell the stepper to move X steps. You tell it to move 1 step and buffer the rest of the movement in software. If the target moves then you update the buffer. The software just looks to see if the buffer is non-zero then issues a ...
