Re: Contests section?
What sort of contests do you have in mind? I joined after the demise of nxtasy.

Re: Dead reckoning and voltage questions.
Assuming you are working with the NXT-G visual environment, you may be able to compensate for the battery voltages effect on turning by setting the steering via a wire to the motor hub. I ran a bunch of experiments in an attempt to relate turning circle diameter to the steering setting but the data ...

Re: Signal Processing
Current robotics depends heavily on probability. Lots and lots of applications of Baye's rule. Some suggested sources: Look through the videos at ai-class.com Look into the courses at udacity.com Seek lecture notes, class outlines, etc. for robotics and AI university courses. Some jargon: Processing...

Re: Gripper using an engine and four half-wheels
An ordinary worm acts like a gear with one tooth. Each turn of the worm moves the gear by one tooth. Some worms have multiple start threads. A two-start worm acts like a two tooth gear. To visualize: wind a piece of string onto a pencil -- that is like a one start thread. wind two parallel pieces of...

Re: Gripper using an engine and four half-wheels
Worm drives work best when the worm is powered and the worm turns the gear. When the gear is powered the friction between the worm and gear keeps both from turning. When a worm and gear are used in machines like jacks and hoists, the friction keeps the load from falling when the crank is released. I...

Details of NXT-G Move Block Question
What is the best source of "deep" information about the NXT-G software and firmware? Right now, I am interested in how the Move Block data plugs interact with visual interface settings. How is the magnitude of the steering input applied? Is it possible to compute the steering input for a g...

Introduction
If you can read this, I have found the secret handshake.
I am an old, retired, engineer and programmer. I survived the Stanford online AI class and have acquired a Mindstorms Nxt set to play with.
After a lot of Google searching, this seems to be the best place too ask technical questions.
