We first told you about the Navy's firefighting robot three years ago. Now, that robot is a reality… in prototype form!

Scientists unveiled a firefighting robot prototype Feb. 4 at the Naval Future Force Science & Technology EXPO, revealing details about its successful demonstrations last fall. The Shipboard Autonomous Firefighting Robot (SAFFiR), sponsored by the Office of Naval Research (ONR), walked across uneven floors, used thermal imaging to identify overheated equipment, and used a hose to extinguish a small fire in a series of experiments Nov. 3-5, 2014 aboard the USS Shadwell, a decommissioned Navy vessel.
Developed by researchers at Virginia Tech, the two-legged, or bipedal, humanoid robot is helping ONR evaluate the applications of unmanned systems in damage control and inspections aboard naval vessels, supporting the autonomy and unmanned systems focus area in the Navy's Science and Technology Strategy.
“We set out to build and demonstrate a humanoid capable of mobility aboard a ship, manipulating doors and fire hoses, and equipped with sensors to see and navigate through smoke,” said Dr. Thomas McKenna, ONR program manager for human-robot interaction and cognitive neuroscience. “The long-term goal is to keep sailors from the danger of direct exposure to fire.”

SAFFiR stands 5 feet 10 inches and weighs 143 pounds. The unique mechanism design on the robot equips it with super-human range of motion to maneuver in complex spaces.
“Balancing on any type of terrain that's unstable – especially for bipedal robots – is very difficult,” said Brian Lattimer, associate professor for mechanical engineering at Virginia Tech. “Whole-body momentum control allows for the robot to optimize the locations of all of its joints so that it maintains its center of mass on uncertain and unstable surfaces.”

As rumored back in January, Google is teaming up with both Sprint and T-Mobile for Project Fi, and the two carriers will provide the cellular service for Google's initiative. With Project Fi service, customers will be able to connect to the fastest network at any given location, whether it's Sprint LTE, T-Mobile LTE, or a Wi-Fi hotspot.
We developed new technology that gives you better coverage by intelligently connecting you to the fastest available network at your location whether it's Wi-Fi or one of our two partner LTE networks. As you go about your day, Project Fi automatically connects you to more than a million free, open Wi-Fi hotspots we've verified as fast and reliable. Once you're connected, we help secure your data through encryption. When you're not on Wi-Fi, we move you between whichever of our partner networks is delivering the fastest speed, so you get 4G LTE in more places.By positioning itself as an MVNO or mobile virtual network operator partnered with existing carriers, Google is able to provide reliable cellular service and its own pricing tiers without needing to build out its own infrastructure. Other well-known MVNO's in the U.S. include Boost Mobile, FreedomPop, and Straight Talk.
Project Fi brings phone numbers to the cloud, letting users talk and text with their personal phone numbers on any phone, tablet, or computer, and it introduces a simplified pricing structure that's easier to understand than most carriers' complicated plans.
There's a single plan that costs $20 per month for talk, text, and Wi-Fi tethering, plus an extra $10 per GB for cellular data in the U.S. and abroad. So a plan with unlimited talk and text with 3GB of data would be priced at $50. Google's also only charging for data used, so customers who pay for 3GB and only use 1GB will get a refund.
Google is debuting a Project Fi early access program that's available to customers who have a Nexus 6. According to Google, this is the first smartphone that supports the hardware and software necessary to work with Project Fi. Nexus 6 users can in areas where -- For more information read the original article here.
