ATLANTA Drive Systems Inc. has expanded its range of servo worm reducers, building a high-torque, economy and basic version to go with the existing high-precision reducer. The high-torque model has 150 percent of the torque capacity of ordinary servo-worm reducers, and a backlash level of less than 1 arc-minute. It has a redesigned output for higher bearing capacity, plus an option for ISO 9409 flanged connections. The economy model has the same torque capacity of an ordinary servo-worm reducer, with a less than 6 arc-minutes backlash level. The basic version has 90 percent of an ordinary servo-worm reducer, and a backlash level of less than 12 arc-minutes. There is a range of motor couplings and mounting flanges available for almost any servo motor, and the hollow bore output works well with output shafts, pinion shafts or other drive elements.
Last year at Hannover Fair, lots of people were talking about Industry 4.0. This is a concept that seems to have a different name in every region. I’ve been referring to it as the Industrial Internet of Things (IIoT), not to be confused with the plain old Internet of Things (IoT). Others refer to it as the Connected Industry, the smart factory concept, M2M, data extraction, and so on.
Some of the biggest self-assembled building blocks and structures made from engineered DNA have been developed by researchers at Harvard's Wyss Institute. The largest, a hexagonal prism, is one-tenth the size of an average bacterium.
