In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you’d like to pitch a project, please send us a tip with “Insert Coin” as the subject line.

Everybody loves robots, but the initial ardor for building one can quickly be snuffed out by the complex reality of actually programming it to do anything. That’s where Linkbot comes in, a new project from the Barobo team that brought us the Mobot. It’s designed as a modular system that can be expanded infinitely with accessories like a camera mount, gripper, and wheels, thanks to three separate mounting surfaces — which also have standard #6-32 screw attachment holes on the mounting plate to attach personality-enhancing cutouts. Despite the expansion potential, though, it can still be used right out of the box to do robotics without touching a lick of code. That’s thanks to several built-in modes like BumpConnect, which permits wireless connections between the modules by touching them together; and PoseTeach, to program complex motions by hand in a similar (but less time-consuming) manner to stop-motion animation techniques.

For those who want to step it up a notch, the system lets you go far past basic mech fun. The Linkbot itself has two rotating hubs with absolute encoding, along with an accelerometer, buzzer, multicolored LCD and ZigBee wireless system with a 100m line-of-sight range. There are also optional breakout and Bluetooth boards to connect sensors like range finders, IR proximity sensors, photo detectors and thermostats. The outfit’s BaroboLink software for Mac, PC or Linux is included to program the Arduino-compatible bot in several languages as well, and can even translate previously created PoseTeach motions into computer routines. So far, the company has created working prototypes and even shipped them to local schools, so if you’re interested, you can pledge a minimum $129 toward the company’s $40,000 target to grab one. That’ll net you a Linkbot, two wheels, the BaroboLink software, access to the MyBarobo community — and hopefully a jolt to your robotics confidence.

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.

The verdict’s still out on whether or not androids dream of electric sheep. But their ability to feel? Well, that’s about to approach levels of human sensitivity. We’re of course talking about the sense of touch, not emotions. And thanks to work out of Georgia Tech, tactile sensitivity for robotics, more secure e-signatures and general human-machine interaction is about to get a great ‘ol boost. Through the use of thousands of piezotronic transistors (i.e., grouped vertical zinc oxide nanowires) known as “taxels,” a three-person team led by Prof. Zhong Lin Wang has devised a way to translate motion into electronic signals. In other words, you’re looking at a future in which robotic hands interpret the nuances of a surface or gripped object akin to a human fingertip and artificial skin senses touch similar to the way tiny hairs on an arm do.

What’s more, the tech has use outside of robotics and can even be levereged for more secure e-signature verification based on speed and pressure of a user’s handwriting. And the best part? These sensors can be manufactured on transparent and flexible substrates like the one pictured above, which allows for various real-world applications — just use your imagination. Pretty soon, even robots will have the pleasure of enjoying the touch… the feel of cotton and maybe even hum that jingle to themselves, too.

Artificial sense of touch gets smarter, lets robots really feel

The latest seafaring robot from Liquid Robotics got an unveiling this morning. Dubbed the Wave Glider SV3, the mobile, amphibious robot is targeted at the (thoroughly unexciting) usual suspects: big oil, the government, and scientific researchers. Apparently those halcyon days of seeking out Guinness World Records are over. Compared with the previous SV2 model, the latest ship runs faster (2.5 knots top speed), carries more (100 pounds, compared to a paltry 40 in the previous ship), and lasts longer (an additional 40 percent of surface area on the deck allows for many more solar cells). All that extra oomph should allow Liquid Robotics’ customers to spend even more time plumbing the Earth’s waters for … well, whatever they’d like. And for the mock G.I. Joe battles that are assuredly taking place with the Wave Glider. Like, come on.
