Re: a Kalman filter to fuse gyro and compass readings

Don't let this thread turn into a flame war or I'll simply lock it and remove the offending posts. I am not hindered by any mathematical knowledge so I don't really care (or know) who is right or wrong but I can spot an impending flame war when I see one. Thanks, - Xander Thank you Xander for stepp...

Re: Stonehenge 3: A fast, precise robot arm

When the program runs, it produces a logfile called logfile.dat on the NXT. If you can send me a copy of it, I can give you a better idea of what went wrong. Even better, I've attached the logfile.dat decoder, the nxt.h file, and the simulator program. Be warned that the simulator's runtime estimate...

Re: Stonehenge 3: A fast, precise robot arm

Thanks for the tip. And now for the usual disclaimer: This code is not as clean as I'd like it to be. It's not as well documented as it should be. But anyone is free to use any or all of it. I'm willing to answer any questions anyone may have. Hansen's first law of software applies (There are only t...

Re: Stonehenge 3: A fast, precise robot arm

I'll happily post the source code, but I'm too much of a newbee to know how to do it properly. At 1500 lines, it seems a bit long to just drop it into the middle of a forum. Just attach the source code file to a post. As long as it's less than 5MB, you should be fine :) - Xander I tried to attach t...

You're only 11!?!? You're going to be awesome before you become old enough to drink. (And then it goes down hill from there).

In any case, thanks for the complement.

Re: Stonehenge 3: A fast, precise robot arm

Philo, thanks for the complement, coming from a man of your caliber, that's a real complement. But the easiest way to look good is to improve something that's already excellent. I'll happily post the source code, but I'm too much of a newbee to know how to do it properly. At 1500 lines, it seems a b...

Stonehenge 3: A fast, precise robot arm

I'm still surprised at how few people have tried to build Philo's stonehenge project which can be found at http://mindstorms.lego.com/en-us/support/buildinginstructions/8547/Bonus%20Model%204.aspx . Building it was not only a real learning experience, but also a lot of fun. It's also kept me very bu...
