Yes, there's a fleet of camera-equipped, remote-controlled blimps live-streaming a bird's-eye view of Google I/O on YouTube, right now. It's called Google AirShow and it's taken over the airspace within Moscone Center. We briefly chatted with Chris Miller, a software engineer with AKQA (the company that put the dirigibles together for Google), about the technology used in each aircraft. It all begins with an off-the-shelf model airship that's flown manually via standard a 2.4GHz radio. Each blimp is outfitted with a servo-controlled USB camera and 5GHz USB WiFi dongle which are both connected to a Raspberry Pi board running Debian, VLC and Python. A custom-designed Li-polymer battery system powers the on-board electronics. The webcam encodes video as motion-JPEG (720p, 30fps) and VLC generates a YouTube-compatible RTSP stream that's broadcast over WiFi. Python's used to pan the servo-controlled camera via the Raspberry Pi's PWM output. The result is pretty awesome. But don't just take our word for it -- check out the gallery and source link below, then watch our hands-on video after the break.

Cornell University may be the host of the Cornell Cup competition, but that doesn't mean it can't bring its own robots to join in on the fun. This year, students brought along a few bots, dubbed dunebots, outfitted with all-terrain wheels and equipped with laser tag turrets. The rugged rig features a pair of cameras, a dustproof and water resistant chassis, air intakes capped with filters, and other components for suspension and steering. Not only does the team plan on releasing code and documentation for the project, but the hardware was designed with modularity in mind, so others can build their own modified versions.

Taking the robot into battle requires two pilots armed with Xbox 360 controllers: one directing where it travels, and another aiming the turret and firing. Driving the buggy over the web is also possible, though it takes a few seconds for it to react. The group also baked in voice controls, to boot. If you're not watching the car duke it out in person, you can even tune in over the web and watch a live video stream from one of its onboard cams. Its top speeds haven't been firmly nailed down, but the team says the bot was running at approximately 35 percent of its full potential, since it was deemed too fast for conference attendees. Hit the jump to catch us talk with the effort's Computer Science lead Mike Dezube, and to see a dunebot in action.

TitanArm already took home silver in a competition for senior projects at the University of Pennsylvania, and now the team behind it is visiting Orlando to compete in the Intel-sponsored Cornell Cup for embedded design. We stopped by the showroom and snagged a few minutes with the crew to take a look at their creation: an 18-pound, untethered, self-powered exoskeleton arm constructed for less than $2,000.

To wield the contraption, users attach the cable-driven mechanical appendage to themselves with straps from a military-grade hiking backpack, and guide it with a thumbstick on a nunchuck-like controller. If a load needs to be held in place, the wearer can jab a button on the hand-held control to apply a brake. A Beagle Bone drives the logic for the setup, and it can stream data such as range of motion wirelessly to a computer. As for battery-life, they group says the upper-body suit has previously squeezed out over 24 hours of use without having to recharge.

These days, music and technology are inexorably linked -- from creation and recording, to distribution and discovery, it's hard to imagine a song reaching our ears that hasn't made its way through some electronic filter. Being the huge music nerds we are, we figured we'd use our April episode to explore the state of the music industry in 2013 and the roles technology has played in its successes and failings. This month, we start things off with a visit to Santa Cruz, where UCSC professor emeritus David Cope has spent decades developing classical music composing computer programs, work he began after one particularly bad bout with writer's block. We also stop by Seattle's Experience Music Project, where we speak to curator Jacob McMurray about the role technology has created in building a better music museum.

Next up, we've got a trio of interviews with artists who are using technology to very different ends in the creation and distribution of their music. John Vanderslice is the founder and proprietor of San Francisco's Tiny Telephone, one of the last remaining analog-only recording studios in a world increasingly dominated by Pro Tools. He's also a successful musician in his own right, who recently opted to eschew the traditional record label model for the release of his two new Kickstarter-backed albums. Hip-hop producer and emcee Black Milk, meanwhile, has taken to recording and producing recordings in his Dallas apartment. We discuss his crate digging, love of analog tools and the role of YouTube and Shazam in his production. And we meet up with indie electronic music Dan Deacon outside of LA's Natural History Museum to talk about his live rig and innovative iPhone app.

What about radio stations, you ask? We pay a visit to Jersey City's WFMU and Santa Monica's KCRW, two of the most prominent freeform stations in a space dominated Clear Channels and internet and satellite radio, to discuss the importance of human curation and embracing the same technology that has spelled the end of so many of their peers. We've also got interviews with Seattle's Sub Pop Records, music criticism site Pitchfork and California record store Amoeba, plus trips to music app developer Smule, internet radio pioneer Pandora and the legendary Moog factory. All that plus another installment of "John Roderick: Famous Prognosticator" and art by cartoonist Jim Rugg.

Oh, and we'd be remiss if we didn't remind you that today is the last day to vote for us in the Webby Awards! In the meantime, check out the full show, after the break.
