An Astronaut Controls a Robotic Dog From Orbit

DLR's four-legged robot Bert explores and monitors the unfamiliar environment. The Surface Avatar Experiment rehearsed an important scenario for future exploration missions on the Moon and Mars. Bert is being developed at the DLR Institute of Robotics and Mechatronics and can walk, trot, gallop, perform a passing gait and even climb. This enables him to cover long distances and at the same time move around in rough terrain or small caves. Credit: DLR.

Swedish astronaut Marcus Wandt took control of a series of robots in Germany while on board the International Space Station, zipping around the Earth at 28,000 kilometers per hour (17,500 mph.) Researchers want to understand how time delays can affect the remote control of robots from an orbiting platform. Future astronauts could control rovers on the Moon’s or Mars’s surface from a spacecraft in orbit. Until now, only wheeled rovers have been part of the tests, but now they have added a dog-like robot called Bert.

NASA Tests a Robotic Snake That Could Explore Other Worlds

Rovers have enabled some amazing explorations of other worlds like the Moon and Mars. However, rovers are limited by the terrain they can reach. To explore inaccessible terrain, NASA is testing a versatile snake-like robot that could crawl up steep slopes, slither across ice, and even slide into lava tubes. Called Exobiology Extant Life Surveyor (or EELS), this robot could cross different terrains and create a 3D map of its surrounding to autonomously pick its course, avoiding hazards to reach its destination.

Lunar Rovers Could be Dropped Into Lava Tubes to Explore Their Depths

Technical challenges abound when doing space exploration.  Some areas are so remote or isolated that engineers need to build a special purpose-made vehicle to visit them.  That is certainly the case for some of the more remote parts of the moon – especially the as-yet unexplored caves on the moon.  Now a graduate student at the Ecole Polytechnique Federale de Lausanne (EPFL) seems to have developed just such an access system.

Swarms of Robots Could Dig Underground Cities on Mars

Underground habitats have recently become a focal point of off-planet colonization efforts.  Protection from micrometeorites, radiation, and other potential hazards makes underground sites desirable compared to surface dwellings. Building such subterranean structures presents a plethora of challenges, not the least of which is how to actually construct them.  A team of researchers at the Delft University of Technology (TUD) is working on a plan to excavate material and then use it to print habitats.  All that would be done with a group of swarming robots.

A Robot Made of Ice Could Adapt and Repair Itself on Other Worlds

This illustration of Jupiter's moon Europa shows how the icy surface may glow on its nightside, the side facing away from the Sun. Variations in the glow and the color of the glow itself could reveal information about the composition of ice on Europa's surface. Credit: NASA/JPL-Caltech

Some of the most tantalizing targets in space exploration are frozen ice worlds. Take Jupiter’s moon Europa for instance. Its warm salty subsurface ocean is buried under a moon-wide sheet of ice. What’s the best way to explore it?

Maybe an ice robot could play a role.

The Woods Hole Oceanographic Institution (WHOI) says their underwater robot has just completed the first-ever automated underwater sampling operation. The robot is called Nereid Under Ice (NEI) and it collected the sample in Greece. WHOI is developing Nereid in association with NASA’s Planetary Science and Technology from Analog Research (PSTAR) program.

Check out this image of the Canadian Space Agency’s (CSA) Canadarm2 on the International Space Station. The CSA’s Dextre is attached to one end of the arm. The Canadarm2 played a vital role in assembling the ISS, while Dextre helps maintain the ISS, freeing astronauts from routine yet dangerous spacewalks, and allowing them to focus on science.

Aquatic Rover Drives on the Underside of the Ice in Antarctica

An underwater rover called BRUIE is being tested in Antarctica to look for life under the ice. Developed by engineers at NASA-JPL, the robotic submersible could one day explore ice-covered oceans on moons like Europa and Enceladus. BRUIE is pictured here in an arctic lake near Barrow, Alaska in 2015. Credit: NASA/JPL

Not all rovers are designed to roam around on the surface of other worlds like Mars. One rover, at least, is aquatic; a necessary development if we’re going to explore Enceladus, Europa, and the Solar System’s other watery worlds. This rover is called the Buoyant Rover for Under-Ice Exploration, or BRUIE.

Shape-shifting Robots Like These Could Be Just What We Need to Explore Titan

When it comes to space exploration, it’s robots that do most of the work. That trend will continue as we send missions onto the surfaces of worlds further and further into the Solar System. But for robots to be effective in the challenging environments we need to explore—like Saturn’s moon Titan—we need more capable robots.

A new robot NASA is developing could be the next step in robotic exploration.
