My $50 Robot
« on: January 18, 2008, 03:53:08 AM »




$17.98
$11.03
$47.14
____
$76.15

Did I miss anything or is there a site with lower prices?
How can I make the transaction safer?
Thanks

hmm...well if you want really cheap prices you can check out www.futurlec.com they have quite good prices.
but when your searching it doesnt come up with very good results. so try using the item type. eg. instead of 120ohm resistor type resistor and select it from the list that appears. hope this helped you

Let me guess Smash,....you are... 12?

I can make out everything except the digikey cart. If you could just copy and paste each one to here and make a list.

if you're going to be soldering a good bit. even after you've done teh $50 robot then get a good soldering iron. invest just like you did with the $30 programmer.


another option is to get the $35 arduino from sparkfun. you'll just need so solder on some header pins, and you wont even need the $36 programmer. just a usb b cable

if you do get the aurdino, the source code might need to be changed a bit to use diferent pins

op sorry for hijacking your thread.

a thing i'd like to add.
the battery seams pretty expensive. you might want to look around for a better deal.
you can get a 9.6v bat w/ charger for $20 at walmart or toysrus

OK smash , thanks for your honesty , thats what I like around here!  ;)


basically you have a tank chassis  without sensors or anything

what  programming language do you use? ,out of curiosity , I tend to use assembly and BASIC for microcontrollers

and by partially you mean have you interfaced the sonar sensor yet, thats the part I am concerned about...

The link is    http://www.freewebs.com/smash-robotics/sonarbot.htm
and Smash , the treads are on soooo loosely , they will come off in about 5 minutes, I doubt that they can drive the bot at all in that condition. Buy a tank toy and hack it with tracks attached , or don't use tracks at all!


Remember , think of what sensors you will add to truly make it a robot and not a chassis
