So how much it would cost for this robot ?? smiley
2  Topics / Robotics / Re: I can't Understand the quadrature encoders ?? on: January 17, 2013, 08:39:23 pm
Ok, so you say that if I need to mesure the speed I need to connect one pin. hmmm so since I use the pololu wheel Encoders I don't have the datasheet but all I need is how to use these encoders as speed sensors for my robot (thay will show in a LCD) ?
3  Topics / Robotics / I can't Understand the quadrature encoders ?? on: January 16, 2013, 10:30:01 pm
Hello, I have try many times to understand how the quadrature encoder work so I can count a speed or steps of dc motor.

can any one Explain how can I use these encoder for count speed ??

Thanks for the suggest and I will try to get round FCB for the top.

Thanks again smiley

what do think that I've to do ( I can't bring back the LCD because I buy it a long time a go) ??

I think you need to post some pictures of the chassis (hopefully fully assembled - with battery holder, motors, and other things in place), the arduino, and the LCD - preferably all together, near each other (as well as separate), perhaps along with some kind of measuring device in the photos, so we can all tell what is what, sizes, etc - in relationship to each other - in order to provide you with potential solutions. Otherwise, we'll all just be making guesses.

Depending on what the chassis is/looks like - you'll likely either need to extend it (up or "out") to make some room, and/or you'll need to use some standoffs or brackets to place the LCD in a different position above or around the Arduino in some manner.

Ok, The Chassis http://www.pololu.com/catalog/product/1505 . And I have used the Arduino Uno with Motor Shield R3, the Battery is rechargeable.

For the picture I didn't assemble it yet but I will do it as I hope it look nice ( I think that I will use another layer on the top to mount the LCD and the Breadboard )

Helo, I've decided to make a robot with LCD, but the problem that the LCD is 4 line so it big to mount (it's size as big as an Arduino Uno) so I think to mount it in a Breadboard, but this will create another problem because the chassis is only 5 inch size.

what do think that I've to do ( I can't bring back the LCD because I buy it a long time a go) ??

Pololu has a lot of nice stuff for beginning robotics, and those parts look fine. You don't really
need encoders at the start, but can always wire them up after things are off and running.
I've built 15 or more robots and never even used wheel encoders, as I like to control the robot
mainly from sensor input [sonars, Sharp IR rangers, photoresistors, bumpers, etc].

However, if you're just getting started, and can afford it, I might recommend the 3pi robot
instead. This will get you off and running really quickly, ie, you'll learn a lot more a whole lot
faster. Appears to be Arduino compatible too.

http://www.pololu.com/catalog/product/975

Robotics involves knowledge in many more areas than most Arduino projects - ie, different types of
sensors, mechanical fab, motor control, general programming, plus robotics-specific programming - and
if you're not already knoweldgeable in a lot of these areas, you'll learn faster with something like the 3pi.






Nice    
suggestion, but I can't get this in my country and I can't also buy it from internet so I can only buy the wheels, motors and Chassis.
thanks very much for your time  smiley-lol

Hello, I just want to ask is Pololu 42x19mm Wheel and Encoder Set , Pololu 5" Robot Chassis RRC04A Solid Red and 50:1 Micro Metal Gear motor are good to Began in robotic????

I don't know about the encoder because I don't need them, but these two just come with it .

Any way is this good for robot build??   
9  Using Arduino / Installation & Troubleshooting / Re: Did the LED pin 13 should be on in all the codes??? on: October 24, 2012, 07:35:06 pm
I think the bootloader might leave pin 13 turned on. You can always turn it off in your code.

Oh, I think thats make sense because I didn't put a code thats make the led high.

I'm I right???
10  Using Arduino / Installation & Troubleshooting / Did the LED pin 13 should be on in all the codes??? on: October 24, 2012, 06:48:12 pm
Hello, I got my Arduino uno r3 and as usual I started with the blank example and every thing works fine, but when I use the servo code example (sweep) I notice that the pin 13 led work contenus (not blanking).

so is it usual that this led works with every code even if there is no setup for it????     
11  Using Arduino / Motors, Mechanics, and Power / Re: Help me for my Continuous rotation servo?? on: October 11, 2012, 06:21:59 pm
No, Iam just asking  smiley .

Ok, did any one now why did the servo didn't move although the code and connection are correct and the servo is unloaded??

I was doubtful that the Arduino it self has a problem in the input / Output.

So, I can't prof that until I can go back to the store and check the both with the engineer their.

See you

Ok, whats the deferent between the ground next to pin13 and the ground next to 5v???
13  Using Arduino / Motors, Mechanics, and Power / Re: Help me for my Continuous rotation servo?? on: October 09, 2012, 03:02:24 pm
No its not loaded and not moving just make the zzzz sound
14  Using Arduino / Motors, Mechanics, and Power / Re: Help me for my Continuous rotation servo?? on: October 09, 2012, 02:43:34 pm
 I did what zoomkat said and I used 4*AA Batteries and I connect the signal to pin9 and the batteries to red wire (servo) and the both servo ground and Arduino ground are connected to the batteries ground (common ground), But it keeps making the sound zzzz.

Note: if I remove the signal wire the sound stops.

So, Does the Arduino have issue ???   
15  Using Arduino / Motors, Mechanics, and Power / Re: Help me for my Continuous rotation servo?? on: October 09, 2012, 12:52:04 pm
Hello, thank you Shredder but I did the same thing and it didn't work. so I think maybe the usb can't power the Arduino enough, is it Possible that if I power it with 9v battery will work???

Because if didn't thats mean that the Arduino have problem and need to be changed.
