MATERIALS: The small spring applied brake series from Ogura (models MCNB 2, 5, and 10) have been redesigned and will now have a thinner profile. The brakes overall reduction in thickness is around 30 percent. Advances in friction material have allowed the brakes to maintain their same torque rating while eliminating the need for higher force springs and a correspondently higher wattage coil. The new thinner spring applied holding brakes are ideal for the servo motor and robotics industries where size and weight is always a concern. Since less steel is used in the coil shell and less copper in the windings, cost of the brakes are also lower than the current MCNB series. On some of the models, the outside diameter has been slightly reduced but all of the models have the same through whole mounting dimensions as the current MCNB brakes, so brake models will be interchangeable.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
