Robotic Vaccum Cleaner -- need help

Since you want the rest of the world to do your homework anyway, just go out and beg or steal a little more cash, buy a Roomba robot and paint it a different color. Submit that as your assignment.

I'd like to say this message is prime evidence of why outsourcing to India is a bad thing, except that we see the same messages in here from students in the US.

some of the regulars.

Uh-huh. Try answering my mail for a few weeks. Two or three times a week I receive an email - most of them from India, oddly enough - which reads something like this:

Hello, Mr. Lewin! I loved to read your [article,book,website,used toilet paper,whatever].

I am studying engineering at [institution]. I wonder if you could give some free advice (I am a student and cannot afford to pay) on this project: [2-3 pages of variably coherent project description] Of course you will understand I cannot give details of this application because it will be for a commercial product.

Respectfully and in eager anticipation. [xyz]

So I don't have a lot of time for freeloaders. Nobody else will do my job for me (day-job work, freelance or study); why should other people get a free ride?

What I find so endearing about this group is the charitable nature of some of the regulars.

Best to ignore the lazy and give help to those who appear willing to learn.

Try a google query like this for example:-

thnx richard for the help. will look at it. well im not lazy, but just need some guidance as to how to go abt it. i didnt ask to build a robot for me. im going to do everything. as this is uncharted territory for me i just dont know how to go abt it. anyway i didnt expect such harsh reply frm others. thnx for the help.

bye, ashwin.

You misinterpret a favor to the begger. Skipping through school and having others do your homework will not help you later in life.

In the engineering field, you'll face problems like this all the time. Therefore you must learn how to answer your own questions. Being resourceful is critical in this field - those who can do it, flourish, while those who can't, drop out.

That said, have a look here:

This will give you lots of help with every aspect of your robot. It covers everything from ohm's law to stepper motor topologies.

If I may make a suggestion... if you do not already have a reliable RF transmitter and receiver, don't bother building your own - that could easly take three months. I would buy a premade RF module, perhaps a pair like the FMRTFQ1 & FMRRFQ1 at

Have fun.

Try at least to do a superficial literature search before you post a "Please do my homework for me" question. India does have libraries, doesn't it?

Outsourcing. Hire someone to drive it in India, connect them via a webcam and a remote control. Job done.
