Malleable Robots to Lead the Way in Space Exploration
Long before mankind sets foot on anything but the Moon, it will have already sent plenty of robots into space to explore the great unknown. Flexible tentacle robots seem to be ahead of the other mechanical device of their kind, though.
Sure, Curiosity, Opportunity and the other rovers are not only good-looking, but also highly-functional. And still, researchers have found a way of making planet exploring robots even better: equip them with tentacle-like arms. Bioinspired robotics is definitely not something new, but it’s the first time it will be applied on NASA’s rovers. More precisely, the arms of this new generation of robots look a lot like elephant trunks, octopus arms and giraffe tongues.
Grasping things and inspecting Mars crevices in a similar way a space-octopus would do weren’t exactly on NASA rovers’ to-do list. In fact, “those are all things that would be difficult for a conventional robot to do,” claimed roboticist Ian Walker of Clemson University in April at a presentation for NASA’s Future In-Space Operations group.
Until now, conventional robots have been designed to function much like humans, and their arms resembled ours, with joints and everything else. In space, that design might not be as useful, though. “What we want to do is something rather different than that,” stated Walker. Their ultimate purpose is to create “something that can adapt its shape more completely down its structure, and to be able to adapt to environments you haven’t seen before. So it’s the non-factory scenario, in many ways.”
Walker has explained that the design of the flexible NASA robots goes beyond elephant trunks and octopus tentacles: “You could reach it out into the environment and grab things, and basically use it as a tunable hook for stability. In some ways, this is inspired by various monkeys.”
An alternative to making their arms highly flexible would be to equip them with different tools with similar functionality: “They would basically have a robot lasso, or a robot rope, that would be part of their toolkit that they could deploy in situations that called for it.”
“Mechanically, these things are cheap and very versatile in what they can do,” added Walker. However, the challenge is “to extract that performance from it. So there are questions of, How much do you need to model it? How much does it need to know?”
The community of tentacle robot researchers have gone a long way in the past few years, and there will be even more progress in this field in the years to come: “The learning curve has been significantly attacked, and I would say that we know an incredible amount more now than we did five years ago. At the progress we’re making right now, I would be surprised if there aren’t things that look intelligent and [are] intelligent in, say, a decade.”

Eleven Great Space Moments Of 2013

Visualized for the Paragon Space Development Corporation, this concept capsule will take passengers to the edge of space where they will be able to observe the curvature of the earth. Inspired by luxury aircraft interiors, the design focuses on enhancing comfort onboard to create a transformative human experience!
World View plans the flights of the capsule, which can carry eight people, to over 30 kilometres (98,425 feet) by means of a helium balloon. The ascent will take between one and a half to two hours. The capsule will then spend between two and six hours at the intended altitude of 30 kilometres, before returning to Earth over the course of 20-40 minutes.
The extended length of time spent in space was a significant driver for the design of the vessel. As director Nigel Goode explains: ‘The idea of space travel naturally brings to mind traditional rocket ships and the aerodynamic forms they command. However, the World View experience is not about speed, it’s about enjoying a once in a lifetime journey. The unique advantage is that the body of work over the last 25 years, from product design to aircraft interiors and hotels, means we always design with the user at the heart. We didn’t just want to design a vessel, we wanted to define what commercial space travel could be. We wanted to create a stylish, elegant, luxurious environment for this unique experience. It was all about finding the right balance between form and function.”
The capsule’s sturdy form was designed to enhance passenger safety. The key design features are the large panoramic windows constructed from an array of small high pressure units. Goode continues ‘It was crucial to find a way to maximise the viewing windows. In our initial design meetings with the World View team, they talked about wanting to start the journey before dawn, so that as passengers rose up to space, they would be able to observe the sunrise, the curvature of the Earth, the thin blue atmosphere and the blackness of space. The windows we designed offer the maximum amount of viewing space for passengers, whilst meeting stringent safety requirements. There is also a cupola viewing dome for unrestricted view of the Earth’s curvature.”
Other features include a lightweight structure, permanently deployed parafoil to maximise safety, science capsule attached to the top of the exterior for potential scientific data readings, deployable landing gear (skids), a reserve parachute for safety and a unique trailer unit for ground transportation and launching platform.
