Supernumerary Robotic Limbs (SRLs) are robotic limbs that, when worn, give you more limbs than you’d normally have. In other words, they’re not robotic limbs designed to replace biological limbs that you might be missing, but rather robotic limbs designed to augment the number of limbs that you have already.
MIT researchers have been developing SRLs that can help you do stuff that would be annoying, uncomfortable, or impossible to do on your own. Today at the IEEE International Conference on Robotics and Automation (ICRA) in Hong Kong, they presented their latest SRL prototypes, with one model featuring a pair of limbs that spring from your shoulders and another with limbs that extend from your waist.
The Cubli: a cube that can jump up, balance, and ‘walk’.
The Cubli is a 15 × 15 × 15 cm cube that can jump up and balance on its corner. Reaction wheels mounted on three faces of the cube rotate at high angular velocities and then brake suddenly, causing the Cubli to jump up. Once the Cubli has almost reached the corner stand up position, controlled motor torques are applied to make it balance on its corner. In addition to balancing, the motor torques can also be used to achieve a controlled fall such that the Cubli can be commanded to fall in any arbitrary direction. Combining these three abilities — jumping up, balancing, and controlled falling — the Cubli is able to ‘walk’.

Last year NASA’s Jet Propulsion Laboratory revealed a Spiderman-inspired grippy clawthat would let spacecraft easily grab onto passing asteroids and comets. Since then the technology has been further refined and now integrated into a rock-climbing robot called the LEMUR IIB that could put Sir Edmund Hillary to shame.
Each of the robot’s four articulate arms is capped with a gripper that uses 750 tiny claws—apparently all hand-crafted by JPL’s summer interns—to grab onto rough surfaces like rocks. The claws are actually strong enough to hold the robot to a surface even upside-down, but in zero gravity there’ll be less forces trying to break its grip.
Tokyo’s Ishikawa Oku Laboratory has created a research robot that can play rock-paper-scissors against a human and win 100% of the time. It cheats.
This $1,350 3D printed spider is about as creepy as it gets.
"The T8 is a bio-inspired 3D-printed octopod robot that can mimic the movements of a real spider. Its movements are courtesy of the Bigfoot™ Inverse Kinematics Engine, which uses complex calculations to control multi-legged robots. The robotic spider uses 26 servo motors and can be pre-programmed with movements or controlled in real-time with a wireless Robugtix™ Controller.”
Engineering at its creepiest?
Twelve-year-old maker Quin already has a company of his own–Qtechknow. He founded a hackerspace in his garage on California’s Central Coast. He helps teach Arduino classes for kids and adults. And he developed the “gas cap,” a baseball hat that detects human methane emissions. (What 12-year-old wouldn’t want that?) And now he’s created the FuzzBot, a cool little robot that not only turns on a dime to avoid obstacles, it helps his mom out by dragging a dust cloth as it makes its rounds.
To build the bot, Quin used the Pololu ZumoBot Chassis Kit for Arduino, an Arduino Leonardo, a pan/tilt small servo, and a Parallax Ping Ultrasonic Distance Sensor. He used wire to attach the servo to the chassis and hot glue to secure the Ping sensor to the top of the servo. He programmed most of the code himself using the Arduino IDE, the ZumoBot library, and the Ping library for Arduino.
Cheetah Robot runs 28.3 mph; a bit faster than Usain Bolt
Last night, I watched a live feed from a command center in Pasadena, California, piped through the Internet 1800 miles to me in St. Louis, Missouri. I heard telemetry and ‘heart-beat’ confirmation tones from a 2.5 billion dollar Mini Cooper sized science lab (the largest ever for a mission) launched 253 days ago, from 353 million miles away, above the surface of another planet. That science lab hit the Martian atmosphere at 13,200 miles per hour. It burned through the atmosphere, and expended a 15 foot diameter heat shield (the largest ever for a mission) that had withstood temperatures of 3,500 degrees Fahrenheit (hot enough to melt every metal you can think of). It rode down on a 51 foot diameter parachute (the largest ever for a mission) designed to withstand speeds of 1450 miles per hour (there was no backup chute). Then the chute was abandoned, and the craft went into free fall for a few seconds. A rocket pack was activated to allow the car sized object to hover over the surface, while a skycrane lowered the entire thing gently to the rocky soil. It landed within a 12 mile by 4 mile ellipse, or around 38 square miles (the size of Barcelona, Spain*), within planetary spitting distance of a 3.5 mile high mountain.
All with zero command input from any human being watching, running on less computing power than the phone in your pocket.
*So take a sheet of paper, fold it in half longways. Now walk about 5,600 miles away. Now hit it with a bullet the width of a strand of DNA (~4 nanometers). That’s what it’s like to land the rover in such a small area from such a long distance.
I know this is a little late to the game but this is the best description of the Curiosity Rover success that I have read.
Easton LaChapelle is now a Junior in high school, he made his first robotic hand, controlled remotely by a glove with sensors sewn into it, won him 3rd place in the Colorado state science fair as a freshman, which reserved him a seat at the national fair in Los Angeles as an observer. This also won him some nice coverage in Popular Mechanics…
