Need Help in building a Obstacle avoiding robot!!!

Posted: 15 Mar 2011 10:53 AM PDT

Hi, friends!! I am preparing a obstacle avoiding robot, and for ease i have named it Intelligent Wanderer, cause it wanders around the place avoiding the obstacles in its path.

In this thread I am attaching two word documents:
1. Project abstract. (submitted in the college)
2. Its the algorithm which I prepared and like which I want my robot to work.

Now, the problem is I am very poor in programming part and thus I know very less about microntrollers and how to program them.

Next, I also want some help in designing the circuit of this particular project.

My last doubt is that I wanted to install a video recording camera on the robot and wanted to record everything captured by it in a particular memory card or some other memory system.
How can i achieve it?

Companies Offering Summer Trainings & Internships For Mechanical Engineering Students

Posted: 15 Mar 2011 07:47 AM PDT

I've been receiving lot of internship related queries from Mechanical Engineering students via email. I'm not at all aware of any companies that offer summer internships or trainings to mechanical engineers.

If anyone knows about them, please post them here. It would be nice if you could also post the region of the company's location and maybe their company URL.

USA Startup Visa Details: What You Need To Know

Posted: 15 Mar 2011 07:10 AM PDT

President Obama and his team have taken steps to ensure that the top engineering talent remains in USA and does not move back to their hometowns. The USA Startup aims at attracting more foreign entrepreneurs to America and provide incentives to the founders to create jobs in the US. If you are an non-American founder, you should know the following about the new Visa:-

Funding: If you are a company funded by a US Angel or a VC firm, the minimum funds you should raise should be over $100,000. In two years time, your company should generate yearly revenues more than $500,000 OR have equivalent funding. You should also create at least 3 new American jobs in 2 year's time.

Students Or H1B Workers: If you're an engineering/science student studying in American University, you need to have an annual income of $30,000 OR assets worth $60,000 and have an investor who's committed to invest at least $20,000 in your venture you'll be eligible for the Startup Visa. You must however create 3 American jobs and reach sales over $100,000 in two years time.

In my opinion, the Startup Visa assumes that every new venture will be funded, while the typical funding stats show that less than 1 in every 100 startups get funded. Also, looking at the startup companies like Twitter, they haven't had a business model for years. Not every startup can generate expected sales or funding in that period.

What's your opinion about the US startup Visa? Do you think it will help in attracting more startups to the valley?

Hey!

(using c)Generating Magic Squares of odd order using De la Loubre's method

Posted: 15 Mar 2011 05:28 AM PDT

Magic squares are nothing but where row,column and diagonal sums are constant
for e.g enter odd number say 9 then you will get the output as magic square as follows
Read the method here

Code:
#include<stdio.h>
#include<dos.h>
void main()
{
int a[100][100],x,y,tmp=1,n;
clrscr();
printf("\n Enter the odd no for which you want to generate magic square\n");
scanf("%d",&n);
for(x=0;x<=n-1;x++)
{
for(y=0;y<=n-1;y++)
{
a[x][y]=0;
}
}
x=0;
y=(n-1)/2;

if(!(n%2==0))
{
a[x][y]=tmp;
hello:
x-=1;
y+=1;
if(tmp>=n*n)
goto raw;
if((x<0)&&(y>=n))
{
x+=2;
y-=1;
goto another;
}
if(x<0)
x=n-1;
if(y>=n)
y=0;
another:
tmp+=1;
if(a[x][y]==0)
{
a[x][y]=tmp;
}
else
{
y-=1;
x+=2;
a[x][y]=tmp;
}
goto hello;


}
else
{
printf("\n you have not entered an odd number\n");
}
raw:
printf("\n");
for(x=0;x<=n-1;x++)
{
for(y=0;y<=n-1;y++)
{
delay(300);
printf("%d\t",a[x][y]);
}
printf("\n");
}

Improving activity on CE Forums

Posted: 15 Mar 2011 05:00 AM PDT

We've discussed this topic many times, but haven't really laid out 'what to do'. So here are few things you can do -

1. Comment on existing discussions. You should have an opinion, question or answer about various topics discussed on CE. If you don't know anything - you can always ask stupid questions :) . No one will laugh at you. It will only improve your knowledge and give you an edge over vast majority.

2. Start new discussions: This looks like a tough job, but it isn't. There are so many topics to discuss. If you are a student, you can ask questions about any topic from your text books, post a problem and discuss it with others.

3. Discuss your question papers. If you had an exam today, take up difficult questions and post them in appropriate technical sections - discuss it with fellow engineers.

See - crowd attracts crowd. If people see variety of topics discussed on CE, they'll be prompted to start new discussions as well.

Does that work? We should at least have 500+ posts every day to make CE really active.
