Battle Bots Reign Triumphant at Robogames

For robots, Robogames is the ultimate fighting competition. It’s where brain turns into brawn, electronics trump athletic prowess and the arena is heavy not with sweat, but with the smell of solder and burnt metal.

At this year’s games, held in the sleepy Silicon Valley town of San Mateo, California, some 500 robots from 17 countries competed, while at least 5,000 spectators witnessed the mechanized mayhem.

“It’s just like the Olympics, but for robots,” says David Calkins, founder and one of the organizers of Robogames.

At Robogames, robots compete for medals across categories such as combat, soccer, hockey, sumo and kung fu. Scores are tallied and medals awarded. But fun and games aside, Robogames also helps advance technology breakthroughs, says Calkins.

“There’s nothing that motivates a person more than losing,” he says. “If you are an athlete you train harder but if you are an engineer you spend more time in the garage and rewrite the code. Without that level of competition, it is difficult to stay motivated.”

There’s more at stake than just medals: Reputations can be made within the metal-Plexiglas robot combat arena. And it’s not just for geek cred: Last year, winning teams from Indonesia and Mexico found themselves invited to meet with the presidents of their respective countries.

Virginia Tech Students Unveil Nation’s First Full-Height, Free-Walking Humanoid Robot

from: Popular Science

by Denise Ngo
Dated 4/27/2010

A group of undergraduate and graduate students at the Virginia Tech College of Engineering’s Robotics and Mechanisms Laboratory (RoMeLa) have unveiled CHARLI, which they are calling the first full-sized, walking, untethered, humanoid robot, complete with four moving limbs and a head, to be built in the United States. While walking robots are nothing new, this one’s humanoid counterparts, such as Petman and Honda’s Asimo, are apparently disqualified for lack of height, autonomy, and nation of origin.

We can’t verify the specs of every humanoid robot in every garage out there, so for now, we’ll accept the university’s claim that their machine is the first of its kind.

CHARLI (Cognitive Humanoid Autonomous Robot with Learning Intelligence) uses a built-in network of pulleys, springs, carbon-fiber rods, and actuators to move his limbs. At the moment, CHARLI can climb stairs and navigate uneven ground, which is more than most humanoid robots can do, and his engineers are working on technology that will allow him to talk.

CHARLI’s inventors began developing him in 2008 under the guidance of Dennis Hong, associate professor of mechanical engineering, director of RoMeLa, and Popular Science Brilliant 10 honoree. While designing CHARLI, they drew inspiration from science-fiction films and from the input of their more artistic spouses.

“The environment we live in is designed for humans: The step size of stairs, the height of door handles, etc., are designed by humans for humans,” Hong said. With that in mind, the CHARLI team focused on making a humanoid robot with motor skills that can handle human tasks. Despite the bar CHARLI has raised for other humanoid robots, its autonomy, hand movements, and overall intelligence, continue to present challenges for Hong and his colleagues.

There are two version of CHARLI in development: CHARLI-L, for Lightweight, and CHARLI-H, for Heavy. CHARLI-L, which will debut in Singapore’s RoboCup tournament later this year, can walk indoors and on flat surfaces. In time, the robot, which stands at five feet — towering seven inches over Asimo — will be able to kick soccer balls.

So far, CHARLI-H is just a leg, but upon completion, those legs will help him jump, run, and kick, as well as use customized actuators to stroll around the campus’s hilly terrain.

Since they had only $20,000 in funds and some donated equipment from National Instruments and Maxon Precision Motors, CHARLI-L’s inventors were forced to improvise on the usual mechanical issues. Check out the video below to see the robots in action and to hear the students talk about how they built CHARLI:

Granted, CHARLI has a ways to go before being ready to freely traverse the great outdoors, but Hong imagines that one day, he will put those moving limbs to good use by serving as a robotic housekeeper.

WOW! You have got to see this!

The past few days I have been away at the American Society for Engineering Education (ASEE) South East Conference. The keynote speaker was Dr Dennis W Hong of the Robotics & Mechanisms Laboratory (RoMeLa) at Vagina Tech.

All I can say is WOW! The talk he gave is very similar to the one embedded below, but I also urge you to go to the RoMeLa website and poke around.

The stuff they are doing includes a “Blind Driver Challenge”, the DARPA Urban Challenge (with a mostly undergraduate student team), the first US bipedal robot to be able to run, and so much more.

To say I was drooling was an understatement!

Also look for him and his students on NOVA and the Discovery Channel.

Human Beats 340-Pound Robot in Football Kick-off

from Wired.com

April 20, 2010

San Francisco’s football team may have its share of detractors, but in a face-off against a robotic kicking machine, Niners placekicker Joe Nedney came out on top.

Nedney was pitted against a 340-pound titanium robot called Ziggy. The event was billed as a man-vs.-machine battle in a leadup to Robogames, a robot competition event that will be held this weekend in San Mateo, California. Nedney kicked a football 45 yards while Ziggy, the robot, failed to clear the goalposts in two attempts at that distance. For a detailed rundown of the play, check out Wired Playbook’s coverage.

Ziggy is no lightweight, though. A star in the robot world, it has a titanium-covered armor plate and has been a gold medal champion at Robogames for three years in a row. Ziggy’s heft and power have made it one of the most powerful amateur robots built. For instance, in one video, Ziggy tosses a washing machine around as if it were a ball.

In practice sessions, Ziggy has been able to kick a ball over 60 yards. But that was on a concrete surface with no headwind.

The football field’s grass surface meant that a major portion of the energy released by Ziggy’s pneumatic arm ended up driving the robot deeper into the ground rather than providing thrust to the ball, explains the BotJunkie.com website.

But all that’s just excuses. For those keeping score, Nedney is the winner — and humans rule.

For now, at least.

See below for a video of the Nedney vs. Ziggy kick-off, plus a closer look at Ziggy.

Science students gear up for robotics Olympics

USA TODAY
April 13, 2010

By Betty Klinck, USA TODAY

In this sport, the players are robots racing up and down a court with a ball to score goals in two nets, bumping and hitting one another to get by, and are controlled by elementary-, middle- or high-school students.

About 400 teams of 10 to 25 students each will engage in these battles of the ‘bots Thursday through Saturday in Atlanta’s 70,000-seat Georgia Dome. The occasion: the FIRST (For Inspiration and Recognition of Science and Technology) Championships.

The event is in conjunction with National Robotics Week, founded by iRobot Corp., and several universities, companies and technology organizations, including FIRST.

Students compete in two-minute high-energy elimination rounds, running between rounds from the court to the pits, “which look like a cross between NASCAR and the Indy 500,” to repair and improve their robots, says FIRST founder Dean Kamen.

Kamen is the inventor of the Segway (the two-wheeled, self-balancing electric vehicle). He began the FIRST competitions 18 years ago to “inspire young people to be science and technology leaders,” according to FIRST’s mission statement.

At 48 inches tall and 117 pounds, Team No. 341’s Miss Daisy robot can aptly maneuver across the field and easily push other robots out of the way. The team from Wissahickon High School in Ambler, Pa., won both the Philadelphia and New York City regional competitions.

“Our robot is very good at controlling the ball and scoring really quickly,” says Team Miss Daisy’s Ryan Morris, a junior at Wissahickon.

The all-girl rookie team from Mary Louis Academy in Jamaica Estates, N.Y., says its robot’s strengths are its speed, agility and excellent steering.

“It’s crazy at the competitions. There’s so much spirit, but everyone’s working together even though we’re up against each other,” says Karra Puccia, a freshman on the Mary Louis Academy team. “There’s a spirit of community.”

Students participate in a six-week design and building period that culminates in regional qualifying competitions leading to the championships in April.

“We couldn’t just create some little sport for them that would be a nerdy little science fair. We wanted to put (the students) in front of the superstars of science and technology — to break the stereotype that all scientists are white males and frizzy-haired psychopaths,” says Kamen, who designed FIRST’s programs to be like a regular sport.

Qualifying teams from all over the world are randomly placed in three-team alliances at the Atlanta Championships.

“The fact that the team that you’re playing against could be with you (on an alliance team) actually works for you. Usually you go and help people with their robots. That’s something I like to do is to go out and help other teams,” says Evan Ostrow of the Miss Daisy Team.

Students are eligible to win up to $12 million in scholarships from FIRST, a non-profit.

“Before I started this competition I wanted to go into computer programming, but now I see there are a lot more fields I like, like mechanical engineering,” says Vanessa Ronan, a junior on the Mary Louis Academy team. “So, I’m not limiting myself.”

Armstrong: Obama NASA plan ‘devastating’

Astronauts warn plan would put U.S. on path to “mediocrity”

April 13: Former astronauts Neil Armstrong, James Lovell and Eugene Cernan urged President Obama to reconsider what they warn would be “devastating” new policies for the future of NASA. NBC’s Tom Costello reports.

updated 5:49 p.m. CT, Tues., April 13, 2010

Editor’s note: In an open letter obtained by NBC’s Jay Barbree, former astronauts Neil Armstrong, James Lovell and Eugene Cernan urge President Obama to reconsider what they warn would be “devastating” new policies for the future of NASA.

The United States entered into the challenge of space exploration under President Eisenhower’s first term, however, it was the Soviet Union who excelled in those early years. Under the bold vision of Presidents Kennedy, Johnson, and Nixon, and with the overwhelming approval of the American people, we rapidly closed the gap in the final third; of the 20th century, and became the world leader in space exploration.

America’s space accomplishments earned the respect and admiration of the world. Science probes were unlocking the secrets of the cosmos; space technology was providing instantaneous worldwide communication; orbital sentinels were helping man understand the vagaries of nature. Above all else, the people around the world were inspired by the human exploration of space and the expanding of man’s frontier. It suggested that what had been thought to be impossible was now within reach. Students were inspired to prepare themselves to be a part of this new age. No government program in modern history has been so effective in motivating the young to do “what has never been done before.”

World leadership in space was not achieved easily. In the first half-century of the space age, our country made a significant financial investment, thousands of Americans dedicated themselves to the effort, and some gave their lives to achieve the dream of a nation. In the latter part of the first half century of the space age, Americans and their international partners focused primarily on exploiting the near frontiers of space with the Space Shuttle and the International Space Station.

As a result of the tragic loss of the Space Shuttle Columbia in 2003, it was concluded that our space policy required a new strategic vision. Extensive studies and analysis led to this new mandate: meet our existing commitments, return to our exploration roots, return to the moon, and prepare to venture further outward to the asteroids and to Mars. The program was named “Constellation.” In the ensuing years, this plan was endorsed by two Presidents of different parties and approved by both Democratic and Republican congresses.

The Columbia Accident Board had given NASA a number of recommendations fundamental to the Constellation architecture which were duly incorporated. The Ares rocket family was patterned after the Von Braun Modular concept so essential to the success of the Saturn 1B and the Saturn 5. A number of components in the Ares 1 rocket would become the foundation of the very large heavy lift Ares V, thus reducing the total development costs substantially. After the Ares 1 becomes operational, the only major new components necessary for the Ares V would be the larger propellant tanks to support the heavy lift requirements.

The design and the production of the flight components and infrastructure to implement this vision was well underway. Detailed planning of all the major sectors of the program had begun. Enthusiasm within NASA and throughout the country was very high.

When President Obama recently released his budget for NASA, he proposed a slight increase in total funding, substantial research and technology development, an extension of the International Space Station operation until 2020, long range planning for a new but undefined heavy lift rocket and significant funding for the development of commercial access to low earth orbit.

Although some of these proposals have merit, the accompanying decision to cancel the Constellation program, its Ares 1 and Ares V rockets, and the Orion spacecraft, is devastating.

America’s only path to low Earth orbit and the International Space Station will now be subject to an agreement with Russia to purchase space on their Soyuz (at a price of over 50 million dollars per seat with significant increases expected in the near future) until we have the capacity to provide transportation for ourselves. The availability of a commercial transport to orbit as envisioned in the President’s proposal cannot be predicted with any certainty, but is likely to take substantially longer and be more expensive than we would hope.

It appears that we will have wasted our current $10-plus billion investment in Constellation and, equally importantly, we will have lost the many years required to recreate the equivalent of what we will have discarded.

For The United States, the leading space faring nation for nearly half a century, to be without carriage to low Earth orbit and with no human exploration capability to go beyond Earth orbit for an indeterminate time into the future, destines our nation to become one of second or even third rate stature. While the President’s plan envisages humans traveling away from Earth and perhaps toward Mars at some time in the future, the lack of developed rockets and spacecraft will assure that ability will not be available for many years.

Without the skill and experience that actual spacecraft operation provides, the USA is far too likely to be on a long downhill slide to mediocrity. America must decide if it wishes to remain a leader in space. If it does, we should institute a program which will give us the very best chance of achieving that goal.

Open Letter to President Obama Regarding Space Policy

This open letter first appeared in wide circulation on the Orlando Sentinel’s blog and has since made the rounds elsewhere.

Dear President Obama;

America is faced with the near-simultaneous ending of the Shuttle program and your recent budget proposal to cancel the Constellation program. This is wrong for our country for many reasons. We are very concerned about America ceding its hard earned global leadership in space technology to other nations. We are stunned that, in a time of economic crisis, this move will force as many as 30,000 irreplaceable engineers and managers out of the space industry. We see our human exploration program, one of the most inspirational tools to promote science, technology, engineering and math to our young people, being reduced to mediocrity. NASA’s human space program has inspired awe and wonder in all ages by pursuing the American tradition of exploring the unknown. We strongly urge you to drop this misguided proposal that forces NASA out of human space operations for the foreseeable future.

For those of us who have accepted the risk and dedicated a portion of our lives to the exploration of outer space, this is a terrible decision. Our experiences were made possible by the efforts of thousands who were similarly dedicated to the exploration of the last frontier. Success in this great national adventure was predicated on well defined programs, an unwavering national commitment, and an ambitious challenge. We understand there are risks involved in human space flight, but they are calculated risks for worthy goals, whose benefits greatly exceed those risks.

America’s greatness lies in her people: she will always have men and women willing to ride rockets into the heavens. America’s challenge is to match their bravery and acceptance of risk with specific plans and goals worthy of their commitment. NASA must continue at the frontiers of human space exploration in order to develop the technology and set the standards of excellence that will enable commercial space ventures to eventually succeed. Canceling NASA’s human space operations, after 50 years of unparalleled achievement, makes that objective impossible.

One of the greatest fears of any generation is not leaving things better for the young people of the next. In the area of human space flight, we are about to realize that fear; your NASA budget proposal raises more questions about our future in space than it answers.

Too many men and women have worked too hard and sacrificed too much to achieve America’s preeminence in space, only to see that effort needlessly thrown away. We urge you to demonstrate the vision and determination necessary to keep our nation at the forefront of human space exploration with ambitious goals and the proper resources to see them through. This is not the time to abandon the promise of the space frontier for a lack of will or an unwillingness to pay the price.

Sincerely, in hopes of continued American leadership in human space exploration.
