German robots could team up to explore lunar craters

While Japan is gearing up to send a miniature humanoid robot to the International Space Station, the DFKI Robotics Innovation Center and the ZARM (Center of Applied Space Technology and Microgravity) are working on a pair of robots that may one day help explore craters on the Moon in search of water ice. The RIMRES (Reconfigurable Integrated Multi Robot Exploration System) project combines a six-legged robot that can be picked up and moved with a faster wheeled transporter.

The SHERPA rover, a 2.4-meter (7.8-foot) long, 200-kg (440-pound) transporter moves using a hybrid wheel-leg system with adaptive suspension. It is therefore able to quickly move over bumpy terrain on its wheels, but can lift each of its four legs independently to climb over boulders or free itself should it become stuck. Its primary duty is to transport a scout robot to and from lunar craters, which it can lift and carry under its belly or with a 1.8-meter (5.9-foot) long arm.

The CREX (Crater Explorer) hexapod measures one meter (3.2 feet) in length and weighs just 27 kg (60 pounds). It's much too small and slow to get around the lunar expanse on its own, which is why it relies on SHERPA to get from place to place. Each leg has four joints and multiple sensors which help it walk on uneven terrain, allowing it to negotiate the steep slopes of a crater's rim. During transportation, it curls its legs up into a neat and tidy package to stay out of the way.

The RIMRES project builds on an earlier project called SpaceClimber, which ran from 2007-2010. That robot was a hexapod similar to CREX that could handle slopes up to 80 degrees and was semi-autonomous, capable of finding its way using built-in sensors. Of course, it will likely be years before these robots make the trip to the Moon, but for now they give us an enticing glimpse into what future space missions may look like.

Google to build green-roof California HQ

An image has been released of what looks set to become Google's new California HQ. Named Bay View, the nine-building campus is designed to maximize the likelihood of innovation-friendly chance encounters between the workforce. "You can't schedule innovation," Google's David Radcliffe tells Vanity Fair . "We want to create opportunities for people to have ideas and be able to turn to others right there and say, 'What do you think of this?'" This philosophy has fostered the design's angular office blocks, arranged back to back like nodding clergy. Despite the 1.1 million sq ft (102,000 sq m), employees will be a maximum of a 2.5-minute walk away from one another, Vanity Fair reports. Perhaps most remarkable is that this is Google's first build. In its 15-year history, Google has only ever occupied buildings previously used by others. "We've been the world's best hermit crabs: we've found other people's shell

Connectify Dispatch combines multiple internet connections into high speed bandwidth

Connectify, a company known for software that can turn your computer into a wireless hotspot, is at work on a new project called Dispatch that will turn all internet connections available to your device into one glorious (and hopefully faster and more stable) stream of high-speed bandwidth. The project appears to take some of its cues from live video broadcasting companies like LiveU , which sells custom made backpacks wired up with 3G/4G and Wi-Fi transceivers. These backpacks then spread the traffic load over whatever available networks it can connect to in order to maximize bandwidth, which is obviously a major plus if you're streaming live video. Dispatch, however, is planned as a software-only solution for the masses – no special backpack required. It will dynamically manage the traffic based on which networks provide the greatest bandwidth and have the clearest signal, which also means that even if one of the networks drops out entirely, you'll still have interne

Holovision aims at life-size 3D projections

Close on the heels of the 21st century complaint of “Where’s my jetpack?” is “Where’s my holographic projector?”. Nothing spells “future” like having a conversation with someone whose life-size image is beamed into the room. Provision of Chatsworth, California wants to bring that one step closer to reality, with its Holovision life-size holographic projector. The company is currently running a Kickstarter campaign aimed at raising US$950,000 to fund the development of new technology for the projector, with hopes of unveiling it next year. The Holovision projector uses what is called aerial or volumetric imaging, which is a way of producing 3D images without special glasses, lenses or slits. It uses a digital LCD screen and a concave mirror to produce the illusion of a 3D image floating outside the projector. In the smaller versions currently made by Provision, this is about 30 cm (12 in) from the display surface, but in the life-size Holovision, this will be further. According
