Robonaut 2
ISS030-E-135161 (13 March 2012) --- A fisheye lens attached to an electronic still camera was used to capture this image of Robonaut 2 humanoid robot during another system checkout in the Destiny laboratory of the International Space Station. Teams on the ground commanded Robonaut through a series of dexterity tests as it spelled out "Hello world" in sign language.
WASHINGTON -- A new robotic space technology spinoff derived from NASA's
Robonaut 2 project someday may help astronauts stay healthier in space
and aid paraplegics in walking here on Earth. Robonaut 2, the first
humanoid robot in space, currently is working with astronauts aboard the
International Space Station.
NASA and The Florida Institute for Human and Machine Cognition (IHMC) of Pensacola, Fla., with the help of engineers from Oceaneering Space Systems of Houston, have jointly developed a robotic exoskeleton called X1. The 57-pound device is a robot that a human could wear over his or her body either to assist or inhibit movement in leg joints.
In the inhibit mode, the robotic device would be used as an in-space exercise machine to supply resistance against leg movement. The same technology could be used in reverse on the ground, potentially helping some individuals walk for the first time.
"Robotics is playing a key role aboard the International Space Station and will be critical in our future human exploration of deep space," said Michael Gazarik, director of NASA's Space Technology Program."What's extraordinary about space technology and our work with projects like Robonaut are the unexpected possibilities space tech spinoffs may have right here on Earth. It's exciting to see a NASA-developed technology might one day help people with serious ambulatory needs to begin to walk again, or even walk for the first time. That's the sort of return on investment NASA is proud to give back to America and the world."
Worn over the legs with a harness that reaches up the back and around the shoulders, X1 has 10 degrees of freedom, or joints -- four motorized joints at the hips and the knees, and six passive joints that allow for sidestepping, turning and pointing, and flexing a foot. There also are multiple adjustment points, allowing the X1 to be used in many different ways.
X1 currently is in a research and development phase, where the primary focus is development, evaluation and improvement of the technology. NASA is examining the potential for the X1 as an exercise device to improve crew health both aboard the space station and during future long-duration missions to an asteroid or Mars. Without taking up valuable space or weight during missions, X1 could replicate common crew exercises, which are vital to keeping astronauts healthy in microgravity. In addition, the device has the ability to measure, record and stream back in real-time data to flight controllers on Earth, giving doctors better insight into the crew's exercise.
X1 also could provide a robotic power boost to astronauts as they work on the surface of distant planetary bodies. Coupled with a spacesuit, X1 could provide additional force when needed during surface exploration, providing even more bang for its small bulk.
Here on Earth, IHMC is interested in developing and using X1 as an assistive walking device. Using NASA technology and walking algorithms developed at IHMC, X1 has the potential to produce high torques to allow for assisted walking over varied terrain, as well as stair climbing. Preliminary studies using X1 for this purpose have already started at IHMC.
"We greatly value our collaboration with NASA," said Ken Ford, IHMC's director and CEO. "The X1's high-performance capabilities will enable IHMC to continue performing cutting-edge research in mobility assistance and expand into rehabilitation."
The potential of X1 extends to other applications, including rehabilitation, gait modification and offloading large amounts of weight from the wearer. Preliminary studies by IHMC have shown X1 to be more comfortable, easier to adjust, and easier to put on than older exoskeleton devices. Researchers plan on improving on the X1 design, adding more active joints to areas such as the ankle and hip, increasing the potential uses for the device.
Designed in an extremely short timeframe, X1 came from technology developed for Robonaut 2 and IHMC's Mina exoskeleton. NASA's work in robotic exoskeleton systems complements work done by other government agencies, such as the Defense Advanced Research Project Agency's Exoskeletons for Human Performance Augmentation Program.
NASA's Game Changing Development Program, part of NASA's Space Technology Program, funds the X1 work. NASA's Space Technology Program focuses on maturing advanced space technologies that may lead to entirely new approaches for space missions and solutions to significant national needs.

R2 Accomplishes Its First Work In Space
03.14.12
Commander Dan Burbank works with Robonaut 2. The robot humanoid
demonstrated its dexterity performing sign language. Credit: NASA TVRobonaut 2 is one step closer to earning its keep on the International Space Station.
R2 – as the robot is called – got its first taste of real work on Wednesday. The crew and ground team had completed all its initial checkouts, and Tuesday installed heat sinks in both of the robot’s forearms to allow it to better dissipate heat and work for longer periods of time.
The first humanoid robot in space was sent to the space station with the intention of eventually taking over tasks too dangerous or mundane for astronauts, and the first such task identified for it was monitoring air velocity. Astronauts onboard the space station generally have to measure the air flow in front of vents inside the station to ensure that none of the ventilation ductwork gets clogged or blocked. The task involves holding a gauge in front of vents in five different locations on the station and taking several measurements of the air flow every 90 days or so.
It’s not exactly a job that requires a rocket scientist – or astronaut – to accomplish, but there are a few things that make it difficult. For one, the gauge has to be held very steady – a challenge for a human being bobbing up and down in microgravity. And the samples can be misleading if there’s another source of air flow in the area – such as a human being’s breath.

Holding still and not breathing happen to be two areas that R2 excels
in, so in some ways the robot is a natural choice for the work. Which is
why Commander Dan Burbank handed the tools over to the robot (after
powering it up and letting the ground controllers command it into
position) on Wednesday to let it give the task a try.
The robot successfully gave the team watching from the ground two good samples taken in front of a ventilation diffuser in the Destiny Laboratory. It wasn’t able to work through the samples as quickly as an astronaut could, and without legs (which are in development on the ground) it could only take samples in one area, rather than all five. But back in Mission Control, the effort was definitely counted as a success.
“I was pretty impressed with the robot’s ability,” said Mari Forrestel, the Environmental and Thermal Operating Systems flight controller analyzing the data R2 sent down. “I think we have some tweaking to do, some fine tuning, but we are definitely looking forward to the robot helping us.”
Ron Diftler, the Robonaut 2 project manager, agreed.
“We’re definitely on the right path,” he said. “Robonaut 2 had a chance to use its first tool today. This experiment is the first step in the robot relieving the crew of every dull task and, in time, giving the crew more time for science and exploration.”
