Hello people
I would like to ask which microcontroller is the best for building robots ...

Motorolla 68hc11
other ....

I think avr are pretty cool .. :D they are easy to use and also have a nice instruction set also they are quite powerful due to there risc nature .

Microchip PIC has got only 36 instructions. There are a lot of free development tools for PIC.

i'm new to robotics too and I have the same confusion. I have spoken to few guys and done a little R&D myself...

The most common is AVR and 68HC11..

but still not made up my mind...any other choice????

I recommend AVR
Why - Cheap and powerfull
remember they are RISC :) helps a lot
a simple 2313 can be connected to a USB ( 1.2 Mbs )
Also real easy to learn and lot of suport

Hope this helps

well, subject says it all....

i am getting a pic axe microcontroller for $10....shud i buy it?... will it help for making a robot for the techfest?.... or shud i wait and find an avr?

pls tell

Hey mandar!!

Welcome to the site...

Where do you live??
Maybe we can help you find the place where you can get the AVR chip..

It is not that PIC is bad.. instead PIC has more online help tools than

If you already know PIC assembly.. then better that you switch to PIC
i.e. if you have less time ..

When is the Techfest and where?

Lots of questions and no answers :twisted:

AVR is faster than PIC. But there are a lot of free tools available for PIC. Also it's easy to assemble a programmer for PIC. Abt the cost, you may get a PIC16F877A for Rs.240/-

hi ..

well, i live in pune, maharashtra..
well the only thing abt microcontrollers i learnt was 8051 and that too in college in 12th...so lets say i know nothing...

so u see.. i just have to learn which to learn first.. hehe...

most of u might know that techfest is in jan, 28-30. so does that mean lotsa time or what?....

btw.. techfest or not,.. i want to buy and play with the uC

hi guys ,
well i am interested in robotics and wireless applications ....i came across PIC 16f84 uC.......can anyone tell me approx how much will it cost me? and where all can i get it .....i live in manipal....near mangalore....


I have registered myself also to this community on the site...

Do searh the forums for listings ... The pic might be costing about Rs 150 similar to the avr 2313 series .

Karn dude!!

nice that you registered n all... juss try to be regular :P

I think "it"(16f84) is 250 bucks..(read somewhere)

nice uC... Moreover... to get uCs and stuff in your locality it is always better to ask the electronic lab staff of your college from where they get the stuff... thay are the best possible help around... if nicely dealt with.. you can get resistors and transistors and stuff for free!! like I do...

the PIC16f84a is availabe for 100 to 135RS in B'bay
I had done my Final year project on a wirless based application using two PIC16f84a.
Worked pretty well.

hi guys....
thanks for ur replies...i will try to find it here.....u see there is only one shop here and the man sells things for very high price,,,,i a;so checked out a site where PIC tutorials were given.....can anyone suggest me where can i get the design for its programmer...

Well, somebady suggest me a site for basics of wireless also....like how does one actually design an atena for specific requirement

see u people
