Canada's main contribution to the US Space Shuttle program has been the Canadian Space Agency robotic manipulator arms, Canadarm and Canadarm2.
Also called the Space Station Remote Manipulator System, the second-generation Canadarm2 helped build the International Space Station, and has been used there to support astronauts working in space, move equipment and supplies, perform maintenance, and manipulate large payloads.
The CSA has unveiled its third-generation Canadarm prototypes, known as the Next-Generation Canadarm (NGC) project. It consists of four robotic elements -- the Large Canadarm, Small Canadarm, Proximity Operations Systems Testbed, and Semi-Autonomous Docking System -- and the Missions Operations Station. The testbed comprises two industrial robotic systems that will simulate bringing two moving spacecraft within a few meters of each other. The mission operations station allows all of the NGC systems to be operated remotely. Combined, all five form a facility the CSA says will help it test and develop new mission concepts and hardware.

The NGC Large Canadarm is a 15m robotic arm that fits inside a minivan when its segments are telescoped together. Although its reach is as long as Canadarm2's, it is lighter and folds up more compactly to fit on future, smaller spacecraft. It will be used on Earth as a testbed to simulate arm deployment during tasks such as capturing and docking spacecraft for refueling. (Source: NASA)
Rob, the Canadarm was designed to work in a weightless, zero-G environment, as we discussed below regarding Lou's comment. So the only "crossover" apps would be others in space, since the arms are too heavy to operate in Earth's 1G.
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
