Robotic “Bees” Are About to Join Astronauts in Space
There are some things only humans can do in space. The rest can be left to robots. To free up valuable time for astronauts living and working aboard the International Space Station, we’re sending three robotic helpers to the orbiting outpost. Developed and built at our Ames Research Center in California’s Silicon Valley, the cube-shaped Astrobee robots will each stay as busy as a bee flying around the space station and assisting crew with routine tasks like maintenance and tracking inventory. The robots will also help researchers on the ground carry out experiments, test new technologies and study human-robot interaction in space. Learning how robots can best work with humans in close proximity will be key for exploring the Moon and other destinations. Get to know more about our new robots headed to space:
The Astrobee robots were tested inside a special lab at our Ames Research Center where researchers created a mockup of the space station’s interior.
The flying robots are propelled by fans. They can move in any direction and turn on any axis in space.
Each robot is equipped with cameras and sensors for navigating inside the space station and avoiding obstacles.
Claw power! Astrobees have a robotic arm that can be attached for handling cargo or running experiments.
Astrobee is battery powered. When its battery runs low, the robot will autonomously navigate and dock to a power station to recharge.
The robots can operate in either fully automated mode or under remote control by astronauts or researchers on Earth.
Astrobee builds on the success of SPHERES, our first-generation robotic assistant that arrived at the space station in 2006.
Two of the three Astrobee robots are scheduled to launch to space this month from our Wallops Flight Facility in Virginia! Tune in to the launch at www.nasa.gov/live.

Plants know when they’re being eaten. There are certain plants that emit toxins as a defense mechanism in response to the sounds of caterpillars chewing - even when the sound is played as a recording. Researchers hope this discovery can someday help reduce the use of man-made pesticides. Source Source 2 Source 3
A newly developed vine-like robot can grow across long distances without moving its whole body.
BY TAYLOR KUBOTA
Imagine rescuers searching for people in the rubble of a collapsed building. Instead of digging through the debris by hand or having dogs sniff for signs of life, they bring out a small, air-tight cylinder. They place the device at the entrance of the debris and flip a switch. From one end of the cylinder, a tendril extends into the mass of stones and dirt, like a fast-climbing vine. A camera at the tip of the tendril gives rescuers a view of the otherwise unreachable places beneath the rubble.
This is just one possible application of a new type of robot created by mechanical engineers at Stanford University, detailed in a June 19 Science Robotics paper. Inspired by natural organisms that cover distance by growing – such as vines, fungi and nerve cells – the researchers have made a proof of concept of their soft, growing robot and have run it through some challenging tests.
“Essentially, we’re trying to understand the fundamentals of this new approach to getting mobility or movement out of a mechanism,” explained Allison Okamura, professor of mechanical engineering and senior author of the paper. “It’s very, very different from the way that animals or people get around the world.”
To investigate what their robot can do, the group created prototypes that move through various obstacles, travel toward a designated goal, and grow into a free-standing structure. This robot could serve a wide range of purposes, particularly in the realms of search and rescue and medical devices, the researchers said.
A growing robot
The basic idea behind this robot is straightforward. It’s a tube of soft material folded inside itself, like an inside-out sock, that grows in one direction when the material at the front of the tube everts, as the tube becomes right-side-out. In the prototypes, the material was a thin, cheap plastic and the robot body everted when the scientists pumped pressurized air into the stationary end. In other versions, fluid could replace the pressurized air.
What makes this robot design extremely useful is that the design results in movement of the tip without movement of the body.
“The body lengthens as the material extends from the end but the rest of the body doesn’t move,” explained Elliot Hawkes, a visiting assistant professor from the University of California, Santa Barbara and lead author of the paper. “The body can be stuck to the environment or jammed between rocks, but that doesn’t stop the robot because the tip can continue to progress as new material is added to the end.”
The group tested the benefits of this method for getting the robot from one place to another in several ways. It grew through an obstacle course, where it traveled over flypaper, sticky glue and nails and up an ice wall to deliver a sensor, which could potentially sense carbon dioxide produced by trapped survivors. It successfully completed this course even though it was punctured by the nails because the area that was punctured didn’t continue to move and, as a result, self-sealed by staying on top of the nail.
In other demonstrations, the robot lifted a 100-kilogram crate, grew under a door gap that was 10 percent of its diameter and spiraled on itself to form a free-standing structure that then sent out a radio signal. The robot also maneuvered through the space above a dropped ceiling, which showed how it was able to navigate unknown obstacles as a robot like this might have to do in walls, under roads or inside pipes. Further, it pulled a cable through its body while growing above the dropped ceiling, offering a new method for routing wires in tight spaces.
For an article about how robots will take us with them in the future. Rather than the normal doom and gloom dystopian singularity people normally predict they thought that robots would form a mutual relationship with people. So I came up with a metaphor for positive feedback loops, hence the hand car! I looked at a lot of ‘space wheels,’ from Mass Effect’s Citadel to Elysium, and admittedly even Gundam Wing, to do the background, but Kali Ciesmier’s SEED poster had the biggest effect on the color palette.
This is TESS, Our Newest Planet-Hunter : TESS, the Transiting Exoplanet Survey Satellite, is the next step in the search for planets outside of our solar system, including those that could support life. (via NASA)
