The same company behind the popular Roomba robocleaner is producing an underwater robot that can stay below the surface for months.

Forget sending huge, expensive, remote-controlled robot probes to Mars--could a swarm of smaller, cheaper units that roam the surface using honeybee-like thinking actually do part of the exploration better and more cheaply?

Japan's $480 million investment in Vietnam's fledgling space industry will improve Japan's galactic public image and give Vietnam its own set of eyes in outer space.

  Find hope in this, NASA, science and Mars fans: President Obama's new stance on NASA's funding will likely pump no less than $6 billion into the agency to create a new heavy rocket sooner than we'd hoped. Mars is its target.

All pointers say that in the next budget from the Obama government, NASA's moonshot Constellation program will be axed. It's not necessarily the end of the dream, though: The plan is to involve private space companies much more.

Update: NASA's 'Moon Bombing' A Smashing Success

NASA's always trying to push the envelope, and tomorrow the space agency's got a really big push: It's going to bomb the Moon. Seriously, and it's all in the name of science, the search for water, and space exploration.

The Tribot may look a little like something you'd find barring traffic at a construction site, but actually it's a sophisticated robot designed to gather data for climate and environmental research from difficult-to-reach places.

Designed by Jonathan Herrle, Josef Niedermeier and Ralf Kittmann, Tribot disposes with the wheels and treads found on conventional robots and instead uses a very weird locomotion tech. Basically it's an adaptive tetrahedron, with actuators in each "leg" capable of adjusting the overall geometry.

To move in a particular direction it changes shape until its new center of gravity tips it over--a way of moving that's particularly effective in the mountainous and glaciated locations it's intended for. At its core sits its webcam-equipped control unit that will also house sensors. Clever stuff, which is probably why it's up for a 2009 iF design award.

All-terrain robotics isn't new. Late last year a robot designed by a British PhD student hit the news. Dubbed the Jollbot, it too uses an alternative drive mechanism: It's a collection of springy metal bars in a spherical shape that also has adaptive geometry. In this case it's powerful enough to let the robot leap over potential obstacles--exactly the sort of all-terrain roving ability well suited to robotic exploration of other planets.

And then there's the continued research into swarm robotics. These are machines with multiple smaller component robots that combine Transformers-like into a larger machine with the ability to traverse terrain that an individual bot couldn't: exactly like this technology demonstrator built by University of Pennsylvania scientists.
