Muscle sensors may let you control a drone by clenching your fist

There might be a more intuitive way to control robots and drones than waggling joysticks or tapping at a screen. MIT CSAIL researchers have developed a control method, Conduct-A-Bot, that uses muscle sensors and motion detection for more ‘natural’ ro...

MIT’s ‘RoboRaise’ helps you lift things by studying your muscles

It's all well and good having a virtual assistant like Alexa or Siri in your lounge, but they make for a pretty useless robotic companion when it comes to shifting a sofa or getting a heavy box from a cupboard. MIT CSAIL has a solution in its sights...

Columbia University's low-cost robotic arm is controlled by facial muscles, we go face-on (video)

We've seen Emotiv's Epoc headset control cars and trapeze acts, but now a small posse of students at Columbia University is teaching it how to control a robotic arm. The appendage, aptly named ARM for Assistive Robotic Manipulator, was envisioned as a wheelchair attachment to help the disabled. According to the team, the goal was to keep costs in the neighborhood of $5,000 since insurance outfits Medicare and Medicaid won't foot a bill for assistive tech that's much more than $10,000. To keep costs low, the crew built the limb from laser cut wood, and managed to keep the final price tag at $3,200. Since picking up EEG signals and interpreting them accurately can be tricky, the group says it settled on monitoring EMG waves, which are triggered by muscle movements, for additional reliability.

Lifting your eyebrows makes the device open its grip, clenching your teeth shuts it and moving your lips to the left and right twists the claw, while other motions are currently handled by using a PlayStation 2 controller. In the lab, the contraption has seven degrees of freedom, but it was reduced to five when we took it for a spin. It was hit or miss when this editor put the headgear on, between making sure facial gestures were spot on and the equipment's attempts to pick up clear signals.

DIY cyborg appendage is less exciting than it sounds (video)

DIY cyborg appendage is less exciting than it sounds (video)

When we envision our transhumanist future, it's a little more profound than simply adding a sixth finger... but we suppose you've gotta start somewhere. Instructables user and employee Frenzy gave himself a rather primitive extra digit as part of a project for an Electronics and Robotics class at San Francisco State University. Sadly he doesn't provide step-by-step instructions for building your own cyborg appendage, but it doesn't seem too difficult. Frenzy borrowed heavily from other projects, using EMG sensors to trigger a servo controlled by an Arduino, which he strapped to the back of a glove. Like we said, doesn't seem particularly hard, once you figure out how to get the microcontroller to play nice with the sensors. Obviously this is just one small step step for DIY cyborgs. Next, we need to graph on a few extra arms to make one-man liveblogging a much simpler endeavor. To see Primitive Transhumanism #2: Sixth Finger in action, head on past the break.

Microsoft granted patent for wearable EMG device

Microsoft granted patent for wearable EMG device

Those muscle spasms? They're now good for something. Okay, so Microsoft's just-granted patent for a wearable EMG device doesn't really thrive off of involuntary twitching and such, but it does use your movements to control your smartphone, notebook and other gadgets. The "Wearable Electromyography-Based Controller," which we first glimpsed back in 2010, uses sensors to interpret the electrical signals generated by a user's muscles, and then communicates with the wearer's computer via a wireless (or wired) connection. Redmond envisions the wearable device in various incarnations: as an armband equipped with sensors, a shirt, eyeglasses and even nodes attached directly to the user's body. In the armband example, motion control could be used to interact with a PMP while the user is jogging. No matter the setup, a calibration process allows the system to locate specific sensors and collect information based on specific gestures or movements, which means playing Guitar Hero with only an air guitar may someday be a reality after all.
