The users look to be a of the users of this Stackexchange, and their experts would bring a different approach than many of our experts, which may be good or bad. The NXT system almost makes their customers users of a service, this site seems to target designers - Similar to the distinction between Superuser and Stackoverflow. Here's a Venn diagram:
While the members of this proposal probably have some 'user' attitude that would not fit well here, most questions probably would fit well. The scope of E&R, in my mind, extends partially into the "Users" domain in the above Venn diagram - mostly for those users who are trying to move into the "Designers" domain. To determine if this is a true statement (and to save you all some time), I've copied over some questions.
Highest ranking (and least disputed) questions:
- I bought an NXT 2.0 set for my 10-14 year old child. What would be a good book to get to learn how to use it?
- What are some good line-following strategies?
- What should I do to get my NXT Brick out of SAMBA mode? ("Clicking Brick Syndrome")
- What is the difference between an analogue and digital sensor?
- What are the advantages and disadvantages of using the LEGO NXT Rechargeable Battery Pack over standard alkaline or rechargeable batteries?
- What are the pinouts of the motor and sensor connectors on the NXT?
- What is a good website that has lots of projects with building instructions and programs?
- How do I control my NXT using MATLAB?
- How can I get rid of an error saying that my firmware doesn't match when I try to download a program to my NXT using BricxCC?
- I have a problem getting pbForth up and running (symptoms X, Y and Z under circumstance A, B and C). How can I make it work?
Some off-topic questions:
- Which sensor is your favorite?
- Which software is the best? NXT-G 1.X/2.0, RobotC, NXC/NBC, Java, etc.
- I want my robot to do A, B, and C. Can you give me a program?
- Can my NXT play music on it? I want to play Pachelbel's Canon in D Major; London Symphony Orchestra's version.
- Should I buy NXT 1.0 or NXT 2.0?
- Where can I find instructions for the midi Millennium Falcon set?
- Are there other good robotics competitions/kits besides Mindstorms?
Note that a few of these were rejected because they were deemed too subjective, not off-topic. Interestingly, "Is it appropriate to use a PID Controller to smooth UltraSonic sensor readings?" got just a few on-topic votes and an "I don't get it" comment. Similarly, "What is I2C? I hear people making sensors that use I2C, but what is it?" only got two votes.
OK, time for some conclusions:
- The members are all about buying components and plugging them together. Duh, but I felt that it needed to be said.
- Members are not really interested in learning about, asking questions about, or giving answers about robotics outside of the NXT system.
- There is less overlap than I would have imagined.
Edit: Conclusions below were from before https://bricks.stackexchange.com/ existed. They're currently in public beta. Ask NXT questions there, not here. Also, remember that we're no longer about robotics.
In the end, I feel that these topics would be welcomed on this site - Not because the attitudes of the members match those of our users, but because the two topics have a lot in common. Similar to the physical/cultural anthropology grouping that Joel Spolsky blogged about, we don't really have a lot in common on the inside, but we can get along. While the C guys and SQL guys on Stackoverflow don't have the same approach to solving problems, they coexist because they're both about programming.
Similarly, NXT people and the EEs on this site can probably get along just fine, and even share some knowledge. When I don't have the time to build a solution from scratch, they'll be there to help me, and when they want to learn about PID controllers and I2C, I'll be there for them. Come on over to our little corner of paradise - the sand is warm, and the C is beautiful!
