Robots developed at the Massachusetts Institute of Technology (MIT) are working everywhere and can move without human assistance in a variety of settings, according to this article from the MIT News Office, "Robots serve humans on land, in sea and air." For example, the famous PackBots were conceived at the MIT and are now used by the U.S. Army in Afghanistan and in Iraq. But engineers and robotic designers at MIT also are developing submarine-like vessels to help the U.S. Navy in mine warfare and battlespace preparation. And others are building 'intelligent' aircrafts, such as a 'robochopper' which would be better suited than surface robots to move in chaotic urban environments. Read more, especially about their 'robotoddler'...Please read the article mentioned above to learn more about robots working on land. This section mainly talks about Professor Rodney Brooks, known for the humanoid Kismet robot, but also for being one of the founders of iRobot, which produces the Roomba, a robotic vacuum cleaner for home use and the PackBots used by the U.S. Army.
But don't miss this page about Rodney Brooks pet projects and this other one about the MIT Computer Science and Artificial Intelligence Laboratory (CSAIL) which plans to develop prototypes of autonomous vehicles and humanoid robots for exploration on the Moon and Mars.
Now, let's go in the sea to check what robots can do there.
Professor Chryssostomos Chryssostomidis, director of the Autonomous Underwater Vehicles Laboratory (AUV Lab), envisions "robots filling the vast void of oceans, roaming around, observing, communicating, and reporting back." His lab has spent the past 15 years developing AUVs that have carried out missions ranging from surveying shipwrecks to testing underwater navigation and communication software.
The lab developed the Odyssey class of submarine-like vessels, which evolved into AUVs produced commercially by Bluefin Robotics, a company that spun out of the AUV Lab and still works closely with it. BlueFin vehicles aid research, survey offshore oil fields, and assist the U.S. Navy in mine warfare and battlespace preparation.
If you want to know more about the Odyssey class of submarine-like vessels, here are two links to its history and to a photo gallery.
Finally, let's look at the sky, for which another group is developing intelligent aircrafts, such as this helicopter.

Eric Feron and his research group in the Laboratory for Information and Decision Systems are working on several projects that may lead to more airborne robots. Those projects include intelligent aircraft, communication among multiple air vehicles, and automated takeoff and landing.
The group has already made progress in two of these areas. The "robochopper," a model helicopter outfitted with a sophisticated instrumentation box, can perform autonomous aerobatic maneuvers at the flip of a remote-control switch. Feron, an associate professor of aeronautics and astronautics, also led the development of an intelligent aircraft guidance system that allows a pilot in one airplane to guide another unmanned airplane by speaking commands in English.
Here are two links to the 2002 announcement of this robotic helicopter, "MIT's robotic helicopter makes first acrobatic roll" and to a gallery of pictures and videos on Aerial robotics.
And for more information about all these MIT robots, you can read the full March 2, 2005 issue of MIT Tech Talk (PDF format, 8 pages, 824 KB). It contains two articles, "Robot's gait mimics toddlers'" (Pages 1 and 4), and "Robots serve humans on land, in sea and air" (Page 4).

Finally, if you're interested by this 'toddler' but don't want to load a PDF document, you also can read "Teams build robots that walk like humans" (February 17, 2005, but updated on March 2, 2005).

Famous quotes containing the words mit, robots, serve and/or humans:
“This summertime must be forgot
MIt will be, if we would or not....”
—Philip Larkin (1922–1986)
“The danger of the past was that men became slaves. The danger of the future is that men may become robots. True enough, robots do not rebel. But given man’s nature, robots cannot live and remain sane, they become “Golems,” they will destroy their world and themselves because they cannot stand any longer the boredom of a meaningless life.”
—Erich Fromm (1900–1980)
“O unbelievers,
I serve not what you serve
and you are not serving what I serve,
nor am I serving what you have served,
neither are you serving what I serve.
To you your religion, and to me my religion!”
—Qur’An. The Unbelievers, 109:1-5, ed. Arthur J. Arberry (1955)
“All humans have a heart that can tell right from wrong.”
—Chinese proverb.
