The picaxe is cheaper than the basic stamp and comes in different connection(pin) sizes(8pin-40pin). Getting a 28x2 or 40x2 would be your best bet for being able to connect to the most sensors plus most people on here have used them so there is a pretty good base of knowledge.
I have been programming in the Basic Stamp $59 and the Propeller which is $8-39 USD depending on the package.
I have a question also on the PICAXE. Are they listed in the microcontroller section of the components pages of LMR? All of the ones that I looked at are listed as "not released yet".
What are the current PICAXE models and where would I buy one?
the X2 parts (last edition, more advanced) parts just came out. They are the 40X2, 28X2 and 20X2 ( i think this last one is still unavailable). You should get them in the 3v version, unless it's a matter of compatibility or some other stuff....
http://184.108.40.206/epages/Store.storefront/?ObjectPath=/Shops/Store.TechSupplies/Products/AXE014X1so by buying one of the first and two microcontrollers would i be able to start making my robot?And if yes what can this support?(servo's , sensors etc) thanx in advance :---)
yes, though I would look at the star here link to get an idea of what you'll need to make a simple one. It uses the simple components you mentioned, ir sensor, some low power motors and servo. This is a good intro into what you'll be getting into as well as the tools that you'll need.
Just a note,if you just want a ready to build setup, the boebot works, if want to try and build something then go with the starthere bot.
first thing: the X2 parts (28X2 and 40X2) just came out so you should get those instead, they only cost a little more (see voodoobot's post). If you want you can get the 3v versions at the same price, i'd personally get those.
second thing: you should really tell us how many things you'll be connecting (just an idea, not the exact number) because maybe a smaller one would do (less space, less money).
