I don't want to be rude, but I beg to differ!  Look at all those tutorials!! They aren't incorrect.  Surely they'll make errors here and there, but just as much as you and I

@robtillaart, I used to play with those as a younger kid!  I was thinking more of an arm, but that would be a possibility I guess

@JimboZA, me too!  I actually have a picture of me as a 5 or 6 year old in a dandelion field.

to completely remove JUST the dandelion or just to like chop off its head ?(henceforth, the robotic lawn mower!)

All very good ideas!! thanks!  I might have to take you up on one of those....my mentor wants to work in the field of social service and health care robotics, so that last one might be a really good idea.  And a robot that runs wires through your house.....I'm thinking of a few ways to tackle that--
1) have a camera and lights on the front of a little bot that has a drill and someway to move around.
2) have a sensor that tells you where the robot is in the wall
3) ...........well, there are a lot of ways--I must ponder some more!  I will get back to you on that!

But if I were to create a robot that paints walls, I feel like i'd be depriving people of jobs!  idk I'll have to see

hmm....interesting...............do they have robots that paint walls for you yet?

As I stated in my P.S. , I don't want people doing the thinking for me, I just want ideas for a little boost to get me going.  Thanks for the contribution!

Helloooo all!!!

I wasn't sure where I should post this, but this seemed an ok place......

 

So I've recently been informed that this summer, as part of my research project, I need to do one of three things--

1) Design, build, and engineer a new robot that has never been created before that would somehow be helpful to the world (either on a small or large scale--it really doesn't matter though)

2) Take a robot that is (somewhat) widely used and build onto it to make it better

3) Take a current (somewhat) well known robot and apply it to something it has never been used for before


I need your ideas and suggestions for robots you think should be built!!  All suggestions are greatly appreciated!! To get into the details of why I'm doing this, I'll explain below--

This will be for my Authentic Science Research project (for the Intel Talent Search) which I will need to write an paper on and submit next fall. My mentor told me two days ago that she wants me to come up with a research idea that I'd be able to complete. But I need your help! I'm a little low on brain juice, so I need inspiration and ideas from you all!! Every idea is helpful!!!

If this plan actually works out and I do one of the above 3 things from now until the fall, I will happily put your name in my acknowledgments section of my research paper, and (if I build a new robot) I will some how get your name printed somewhere visible on the bot. I know the reward is not that intriguing, but its something!

Thank you all so much and I hope to hear from you soon!!!

P.S.--I'm not asking you to come up with a project, just any ideas of robots you might want to see made.

Cheers!

I'm turning 17 soon and I still don't have one.  I actually get a lot more done (since I don't have one) than my friends that do have a facebook.  I'm technologically and digitally advanced, but I'm sticking out the age of social media

I've used sparkfun only and the reason I like them best is for the support, the easily navigatable website, great user and customer support, and the wide variety of products they sell.  And I've had email conversations with many people at SparkFun, why didn't you think they did that?  Their prices may be a bit high for individual parts, but that's what we have digikey and mouser for.  they even recommend buying from other places if you order small pieces like that in bulk.  Also, if you complain about the price being so high for whatever product and show them an example of the same product somewhere else for less, they'll either tell you why their part is more expensive, or they'll lower the price.  Sparkfun isn't just an electronics website--Their a family!!  Plus, where else do you find so many great tutorial, daily videos/posts, and awesome people like that?
10  Using Arduino / General Electronics / Re: Servo twitch on startup on: February 05, 2013, 03:46:16 pm
When you start up an Arduino, the servo will automatically jump the servo a bit and move.  One way to prevent this could be to always have a voltage applied, but maybe like a "sleep" mode where no power is being drawn other than the LED on the main board.  Does that help at all?

Are they connected to the correct port number for each?  It's probably very easy to mix up port numbers with 8 different boards!

didn't realize i was missing my ground and resistor to the button....sorry about that!! that was silly of me
13  Using Arduino / LEDs and Multiplexing / Button and LED problems on: December 31, 2012, 11:53:32 am
Hi all, I've been messing around with some examples recently, and I decided to look at the "button" example so I could incorporate it into my AGV.  I'm having what appears to be a static electricity problem.  Whenever I come within 2 inches of the wire that connects the Arduino to the button, the LED automatically lights up.  When I go to press the button, the LED turns off.  And here's another weird thing that's happening--When I go to push the button with a solid wooden ruler, the LED stays off when I push the button.  I'm 99.99% positive I have the wiring correct.  Can anyone help me here?
14  Using Arduino / Programming Questions / Re: Mapping values from an IR sensor to a servo on: December 23, 2012, 01:11:21 pm
Well, I figured out what the error was-- I didn't change all the values to match each sensor...


This
Code:
else if (Prox04 <=25)
  {
    rightSide = Prox01;
    rightSide = map(rightSide, 5, 25, 65, 95);
    Steering.write(rightSide);
  }

Should have been THIS
Code:
else if (Prox04 <=25)
  {
    rightSide = Prox04;
    rightSide = map(rightSide, 5, 25, 65, 95);
    Steering.write(rightSide);
  }

Silly mistake....Thanks for all the help!
15  Using Arduino / Programming Questions / Re: Mapping values from an IR sensor to a servo on: December 23, 2012, 11:22:32 am
The output to the Serial monitor?  do you mean  
Code:
Serial.begin(9600);  //opens the serial monitor at 9600 baud

Printing the values first actually does tell me when the code jumps into the else block because when the code starts, the rightside and left side values are defaulted to 0.  When that number changes, then I know it jumped into the else block.  when it is not in the else block, the value doesn't change at all.  In order for the first if statement to be true, ALL of the sensors (there are actually 5 total, but I don't really use the center one)  must have a reading of above 15.  And all of the values are printed, so I can see when the value falls below 25.

But besides that, am I using the map function correctly?? I can't find anything that specifies what values should go in the four spots of the map function.
