10 Tips to Make Robots?

10 Tips to Make Robots?   by Anna Fowler


Learning and Doing are two different things. It is important to learn and not just do. Making a robot is fun, but it must be thought through. RoboGalaxy provide online robotics education and help you learn from "What is a robot" to "designing and programming robots". These learning can be taken forward to create robots may on kits like LEGO MINDSTORMS NXT, VEX, BIOLOID, etc

We bring your tips to make robots by taking an example of robotics projects of a mobile autonomous robot with ball dispensing capabilities on the move. This can be a fun robotics project, and it was a challenge in WRO (World Robot Olympiad) 2012. Here are the tips to make robots -

1. A good starting place for any design is by making a rough sketch of what you want your design to look like. The act of giving that idea in our head a definitive form helps us to more clearly understand the design.

2. Once you have a rough sketch of the robot you wish to build; label it. This is most important as it will help you understand where all the different components we discussed earlier go in your design.

3. Once you have with you, your labeled sketch start building a rough "proof of concept" model in the following order

4. Start from the bottom up, the chassis of your robot will be responsible for holding all the various components together so it's a good idea to start by making a chassis for your robot. Add motors and your chosen type of wheels/treads to this chassis. Remember that at this time you should not be looking to finalize your design and to lock everything down, instead it is better to keep things simple and easily modifiable so that you can affect correction easily.

5. Once you have your chassis ready, test it out by making it move forward and performing a couple of turns. This test will help you get a feel for how the robot will move, make any changes necessary to improve your design at this point. Try laying out some obstacles in the way of your robot and see how it tackles them. Note down your observations and improve your design.

6. Once you have a chassis design that works as it should then its time to proceed onto the next component; the ball dispensing mechanism.

7. As before, start by drawing a rough sketch of your intended design. Next build a rough model of the ball dispenser on top of the chassis you built in the last step. At this point it is necessary to build the complete mechanism capable of holding all 12 balls, just enough to test the design concept.

8. Load a few balls into your model and test it to see if can dispense that balls reliably every time, tweak your design as required.

9. Next add a downward facing color sensor to your chassis and write a simple program that displays the detected color on the NXT's display. This will help you test the reliability of your color sensor.

10. Place your robot on test surfaces of the different colors that your robot needs to detect on the arena (white, green, yellow, red, blue). Check and see if the detected color is indeed the color of the surface. Repeat this test in a brightly lit room and in a dimly lit room, this test ensures that your sensor doesn't have problems working in various lighting conditions and performs reliably.

End of the Line for Roadrunner Supercomputer

End of the Line for Roadrunner Supercomputer   by Vicky


It's the end of the line for Roadrunner, a first-of-its-kind collection of processors that once reigned as the world's fastest supercomputer. The $121 million supercomputer, housed at one of the premier U.S. nuclear weapons research laboratories in northern New Mexico, will be decommissioned Sunday.

The reason? The world of supercomputing is evolving and Roadrunner has been replaced with something smaller, faster, more energy efficient and cheaper. Still, officials at Los Alamos National Laboratory say it's among the 25 fastest supercomputers in the world.

"Roadrunner got everyone thinking in new ways about how to build and use a supercomputer," said Gary Grider, who works in the lab's high performance computing division. "Specialized processors are being included in new ways on new systems and being used in novel ways. Our demonstration with Roadrunner caused everyone to pay attention."

In 2008, Roadrunner was first to break the elusive petaflop barrier by processing just over a quadrillion mathematical calculations per second.

Los Alamos teamed up with IBM to build Roadrunner from commercially available parts. They ended up with 278 refrigerator-size racks filled with two different types of processors, all linked together by 55 miles (89 kilometers) of fiber optic cable. It took nearly two dozen tractor trailer trucks to deliver the supercomputer from New York to northern New Mexico.

The supercomputer has been used over the last five years to model viruses and unseen parts of the universe, to better understand lasers and for nuclear weapons work. That includes simulations aimed at ensuring the safety and reliability of the aging U.S. arsenal.

As part of the U.S. nuclear stockpile stewardship program, researchers used Roadrunner's high-speed calculation capabilities to unravel some of the mysteries of energy flow in weapons.

Los Alamos has been helping pioneer novel computer systems for decades. In 1976, the lab helped with the development of the Cray-1. In 1993, the lab held the fastest supercomputer title with the Thinking Machine CM-5.

"And to think of where we're going to be in the next 10 to 15 years, it's just mindboggling," said lab spokesman Kevin Roark.

Right now, Los Alamosâ€"along with scientists at Sandia National Laboratories in Albuquerque and Lawrence Livermore National Laboratory in Californiaâ€"is using a supercomputer dubbed Cielo. Installed in 2010, it's slightly faster than Roadrunner, takes up less space and came in at just under $54 million.

Roark said in the next 10 to 20 years, it's expected that the world's supercomputers will be capable of breaking the exascale barrier, or one quintillion calculations per second.

There will be no ceremony when Roadrunner is switched off Sunday, but lab officials said researchers will spend the next month experimenting with its operating system and techniques for compressing memory before dismantling begins. They say the work could help guide the design of future supercomputers.

Online Classifieds Offer Unlimited Choices to Buy Stuff Online by Gosell Australia

Over the past few years, E-commerce has picked up a big way. People are increasingly making purchases online since it is hassle free and offers choices greater than the ones you can find in retail stores. The immersion of e-commerce in our daily lives can be determined straight from the fact that E-Commerce business has grown manifolds and is slated to touch the $1 trillion mark this year! Until 2011, the number of online selling websites was pretty low but within a year, there’s been a monstrous growth. One of the most famous types of e-commerce websites includes online classifieds, which allows you to buy stuff online.
Classified websites are just an extension to the newspaper classifieds we’ve grown up reading. Classifieds have overridden their traditional newspaper counterparts in a huge way and offer a lot of benefits that the newspaper classifieds could never. Technology has come to play and therefore enabled the creation of user friendly online classifieds which are now preferred way more than newspaper classifieds. Online classifieds have also minimized all the cons you might have experienced while reading traditional classifieds. To add more plus points to the list, it is friendly both to the buyer as well as the seller.
The fact that online classifieds are popular today cannot be attributed to their features alone. Since the inception of classified advertising in newspapers, the ‘wanted’ ads have been really popular. A lot of people have constantly made fun of the fact that ‘wanted’ actually looks like a police notice! However, whenever there’s been a requirement of employees/workers/part-timers in any company, organization or small firm, they’ve placed an ad stating ‘Wanted - 2 sales executives’ or ‘Want - 3 Advertising Managers’ etc. As a result of their popularity, people have taken up to online classifieds too in a big way since it offers classifieds plus amazing benefits.
Advertisers have actually started employing the use of internet classifieds as it enables them to sell online free of charge. The same isn’t the case with newspaper classifieds, who charge money for printing your advertisements. This makes free online advertising a natural choice. Also, the growth in the number of internet users is significantly contributing to this industry. As more and more people are learning the internet, and as a newer generation is coming, there’s a spurt in the number of netizens.
While usual e-commerce websites ask you to register at the time of checking out, online classifieds don’t. You will be amused to know that one-fourth of the time, users cancel their orders when prompted to register. The preference of online classifieds is thus natural as both the buyer and the seller can exchange contact details without registering on the website.
