High positional accuracy in a zero-backlash gearhead
Built for OEM robotic applications, the SHD Gearhead Size 14 has a 1.5 arc-min positional accuracy and ±5 arc-sec repeatability. It has a high-precision harmonic drive gearing and high-capacity cross roller bearing, with a rated torque of 33 inches-lb and a maximum torque of 310 inches-lb. It has an outer diameter of 70 mm, is only 17 mm long, and comes in 50:1 and 100:1 gear ratios. It has necessary motion control components like the harmonic drive gear and the cross roller bearing, which allows it to be incorporated into the machine housing.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
