If you’ve ever wanted your own self-driving car, this is your chance. [Sebastian Thrun], co-lecturer (along with the great [Peter Norvig]) of the Stanford AI class is opening up a new class that will teach everyone who enrolls how to program a self-driving car in seven weeks.

The robotic car class is being taught alongside a CS 101 “intro to programming” course. If you don’t know the difference between an interpreter and a compiler, this is the class for you. You’ll learn how to make a search engine from scratch in seven weeks. The “Building a Search Engine” class is taught by [Thrun] and [David Evans], a professor from the University of Virginia. The driverless car course is taught solely by [Thrun], who helped win the 2005 DARPA Grand Challenge with his robot car.

In case you’re wondering if this is going to be another one-time deal like the online AI class, don’t worry. [Thrun] resigned as a tenured professor at Stanford to concentrate on teaching over the Internet. He’s still staying at Stanford as an associate professor but now he’s spending his time on his online university, Udacity. It looks like he might have his hands full with his new project; so far, classes on the theory of computation, operating systems, distributed systems, and computer security are all planned for 2012.

What’s better than one amazingly acrobatic quadcopter? How about a swarm of acrobatic micro-quadcopters? It’s not a rhetorical question, but an experimental reality. A team at the University of Pennsylvania are showing off their latest round of hovering robots which can move in formation and alter their orientation as a swarm.

You may remember us salivating over the unbelievable stunts the team pulled off with a single ’copter back in 2010. That device needed a sophisticated camera installation to give provide feedback, and this uses the same framework. But we don’t that detracts from the achievement; it’s simply a future hurdle for the project.

The video after the break shows some of the stunts the slew of whirring devices are capable of. Watching them move as a grid, and even landing simultaneously, we can’t help but think of the Dog Pod Grid from Neal Stephenson’s book The Diamond Age. It was used as a protection system, keeping unwanted flying intruders out. Doesn’t sound so far-fetched any more, does it?

After the terrible tragedy in Fukushima, the cleanup and damage assessment has begun. A robot operator, known only as [S.H.] has decided to write a blog about their efforts.  As pictured above, they are using [iRobot] models, including the [510 Packbot], and the [710 Warrior].

Since cleanup efforts started, [S.H.] was posting on his or her blog daily.  After word of this blog started getting out via various social media outlets, the blog was mysteriously taken down. The blog was at times critical of elements of the cleanup effort, but it’s unknown why the disappearance happened. Efforts to reach [S.H.] were unsuccessfull according to [IEEE].

Fortunately, before the takedown, [IEEE]‘s [Erico Guizzo] decided to make a copy of the posts. These have been translated into English and portions are now available at the link listed above. Be sure to check out robot training video after the break. Read the rest of this entry »

Even though abstract expressionism died out several decades ago, robots are still chugging along dripping nihilistic pigment onto a cold, uncaring canvas. [Liat] and [Assaf] created a robot named The Originals Factory to create paintings in the style of abstract expressionism, a style of painting that is arguably best represented by [Jackson Pollock] and his ‘drip paintings.’

The build is surprisingly simple – there are four containers filled with C,M,Y, and K pigments. Pumps transport these paints to a print head mounted on an aluminum rail above a canvas. The software portion of the build is rather interesting. Instead of pixels, the image is rendered in ‘vixels’ – vertical lines of a specific length and color. Although we don’t see any examples of more precise work, [Liat] tells us The Originals Factory can be used to plot graphs on the canvas.

Check out a video of The Originals Factory squirting paint down a canvas after the break.

[Pythagoras] is a delta robot built originally using RC servos. Humbly, [Aaron] “concedes” that the first version of his delta robot using hobby servos was easy to build. As anyone who has built any kind of robot knows though, there is definitely a lot of work involved in even the simplest robot. Coordinating three axes and programming it to draw a picture is a really great accomplishment.

The second version, however is currently in development and uses stepper motors instead of servos. These upgraded motors should make the robot faster, more controllable, and more accurate. This version is at least somewhat working as evidenced by the time-lapse video after the break.

Although the title page listed above is a little sparse on build details, if you dig deeper into the page, there are actually 15 articles about the ‘bot, so be sure to poke around. Read the rest of this entry »

Meet Boxie. He’s a robot videographer with levels of interaction we haven’t seen outside an episode of Dora the Explorer. The project was conceived by [Alex] as his MIT thesis project to see if robots can use humans to make themselves more useful. All we know is Boxie is freaking adorable, as evidenced by this video.

The idea behind Boxie was inspired by Afghan Explorer to capture video in an attempt to tell a story. In the videos (after the break), Boxie wanders around the halls of MIT searching for people to help him (“can you carry me up the stairs?”) and tell stories (“what do you do here?”). It’s an experiment in autonomous documentary directorial skill that was edited down into a video that made sense.

[Alex] designed Boxie to be the cutest thing we’ve ever seen so he could elicit a response from the subjects of the documentary. We’re going to say the voice helped, but [Alex] also found the cardboard robot factor also played into the success. Boxie was originally planned to have a plastic skin, but [Alex]‘s friends thought it looked really creepy. They suggested that [Alex] go back to the prototype cardboard body. All we know is there’s a robot cuter than a Keepon, finally.

This is Chippu, a robot that [Achu] has been working on for some time. His most recent addition was to give the robot the ability to respond to voice commands. This is accomplished using a variation of the open source Continuous Speech Recognition package called Julius.

The package depends on two main parts, a set of acoustic models which let it match incoming sounds and a reference library of grammar which is built from those sounds. [Achu] published another post which goes into detail about using Julius on a Linux box. It seems like this is possible with less robust hardware (ie: on an embedded system) if you narrow down the number of acoustic and grammer models that need to be matched.

For now, Chippu is getting commands from a computer that runs the CSR. But this was only used as a proof-of-concept and [Achu] plans to transition the bot over to smaller hardware like the BeagleBoard.

Check out the demonstration of Chippu responding to voice commands in the video after the break.

[Mike Li] is showing of his stair climbing robot. It’s a bot that cruises around on a pair of tank treads, but some interesting modifications gave him the traction needed to ascend a flight of stairs without slipping backward.

The image above shows this process in great detail. You can see the unaltered treads leaving the top of the image. In the foreground, strips of rubber-backed rug add some sticking power to the otherwise smooth surface. To really stop the bot from slipping, segments of CAT5 cable have been screwed to the tread at regular intervals, holding the carpeting tightly in the process.

You can see in the video after the break the little robot has no problem with rough terrain. The design was inspired by the iRobot Packbot which has a set of treaded appendages sticking off the front end. These ensure that the vertical face of an obstacle, such as the beginnings of a staircase, can still be reached by the main set of treads.
