RObot #1 (Mark II)
Hi people
···· I kinda suck at programming, so I decided to go with an oopic stamp for my next project. Electronics for dummies say they're easier to program. Does an OOpic 24 pin stamp work on a BOE?
Also, I want to know if there is a 'sound to text sensor' that can hear what you say and give input. Does An RFID tag have a different frequency then another RFID tag? Does the GPS sensor work inside?
Mynewest and coolest program is a robot that uses GPS, RFID, Compass, and Ping))) to carry my books from one class to the next. I figure I'll power it up, swipe an RFID tag, and it will go to the class where the RFID tag says to in the program. The ping sensor will be to stop if a person's in front of it. the SOund to text will be so I don't need like 6 RFID cards to make it work, I could say "science" and it will go to science.
This is the spring board for a robotic car I will build.

There are sound to text devices. You have to hook up your own microphone and you have to program them with a vocabulary. They're also not cheap and not as reliable as you might think. Good voice to text processing for more than a few words really takes a lot of processing power.
There are many different RFID frequencies. The ones Parallax uses works at 125KHz. Read the Wikipedia article on RFID for more information.
GPS sensors either don't work at all or work poorly inside. They're really designed to work with a direct view of the satellites in the sky. They also don't have the kind of resolution needed for your project. Minimum distances are on the order of many feet.
Consider using a standard universal remote control. These use IR and a Stamp can receive and decode it. You could create a simple map inside your program with distances from one doorway to the next and the relationships from one hallway to the next. The robot could use its compass and PING sensors along with keeping track of its movements (wheel revolutions travelled) to compare its current surroundings to the map to figure out where it is. There are always errors in determining position and referring to markers along the way (like doorways) can help.
now how would I go about making a map for it??? is there any other language that's easier than basic???

the Ping Sensor I have Hooked up does not light up-i know it does because i did have hooked it up where it lights up
I am following all the instructions in the parrallax manual... is it faulty or wrong wiring or what??

"faulth or wrong wiring or what??" Who knows? You will need to make up a diagram showing how you've hooked things up and post that. We can't guess what you've done. It may also be your programming. The PING has to be triggered by a short pulse as described in the documentation for it.
How about learning first how to program and how to do something simple like turn an LED on and off and detect whether a switch is on or off. That's a good beginning.
The Ping))) sensor LED only lights up when you are actually ranging with it.
When the PING))) is triggered the LED comes on as the signal line goes high. At the receipt (or timeout) of the return pulse, the signal line goes low and the LED goes out. So if the LED is never coming on, then the PING))) is not seeing the trigger pulse or there is a problem with your power supply or connections.

I can help your book-carrying·robot; however I first have a few questions for you. First, what kind of size limits do you have? Does it need to be large to carry·text books, or can it be fairly small? Second, what type of budget are you working with? Earlier on, while working on my robot FHR (five horse robot) I had too much I needed to buy, and very little money. This really slowed me down.
One more thing that could help is a description of what·you would like your robot to look like. One easy way to do this is to sketch a picture and post it here, or make a CAD image. With this done, I'll be able to give you some·help.
BTW, look at the beginning of my·FHR robot post. You'll find it started very similarly to·yours right now.

uses h-bridge, ping, and IR beacon to follow me around
should I use Prop, pr BS2

Also, you haven't stated what kind of budget you're working with. If it is fairly limited, a good place for you to get parts is the junkyard. You can get old motors out of car doors and the windshield wiper motors could work well, too. If you aren't too worried about speed, there some fairly powerful brushless motors in old VCRs, as well.
·
Also, what kind of a frame are you thinking about? Will it be plastic, aluminum, wood? If you are looking to save weight on your project, PVC board might be interesting to use, as well. The only problem with it, however, is it is easy to bend and dent. In some cases this might be good, like if you are worried about your robot scratching things up in your school. If you are interested in it, there is a link below.

gonna use like ...
pvc plastic stuff
ping is just so it doesn't run anyone over.

So does that mean you'll have to cut costs to save money or not? That's what I meant by budget--how much you want to spend on the robot. Sorry abou' that.
