50 years ago: On the way to the Moon
In the race to fly humans to the Moon in the 1960s, the Soviet Union supported two separate programs. One based on the Saturn-V class N1 Moon rocket planned to land a single cosmonaut on the Moon. The other, the L1 or Zond program (modified Soyuz spacecraft), planned to send two cosmonauts on circumlunar missions without a Moon landing. [Countdown Series: 50th anniversary of Apollo 11]

Molded threads and how to design them
Molded threads are everywhere as part of mass-produced plastic parts we encounter every day, parts that were made using multi-cavity, highly automated molds costing hundreds of thousands of dollars and requiring many months to design and manufacture. But what if you don't have that kind of time or money? No worries, that's what contract manufacturers like Protolabs are for. Just follow some basic design guidelines, and understand that the threads found on molded parts are a bit different than the ones made in a machine shop.

Robots can now pick up any object after
inspecting it

Breakthroughs in computer vision have enabled robots to make basic distinctions between objects, but even then, they don't truly understand objects' shapes, so there's little they can do after a quick pick-up. But researchers from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) say they've made a key development in this area of work.

Alternative to traditional drive systems
Nexen Group has introduced a stainless steel version of its patented precision roller pinion system (RPS). The Nexen RPS engages two teeth simultaneously to achieve superior accuracy with zero backlash at any length. The system is also extremely quiet and 99 percent efficient. Stainless steel makes the system corrosion resistant, with a long life of up to 36 million meters. Nexen's RPS provides a low-maintenance, durable alternative to rack and pinion, ball screw, and belt drive technology. The RPS is used for a wide range of applications including laser cutting, plasma cutting, and gantry applications.

Top Tech Tip: Choosing between brush and brushless DC motors -- What are the tradeoffs?
Designing a system that involves motion and performs as intended requires choosing the right motor. The most fundamental decision involves commutation type. In some cases, mechanically commutated brush motors provide the best solution for the budget. In other cases, only brushless DC (BLDC) motors will do. Allied Motion provides a comprehensive review of the technology, along with tips and tricks for choosing the right solution for a given application.

50 years ago: NASA solves the 'pogo effect' -- gets one step closer to moon landing
On July 18, 1968, NASA announced that engineers had found a solution to the problem that occurred near the end of the Saturn V rocket's first stage during the uncrewed Apollo 6 mission. During the last 10 seconds of that first-stage burn, the rocket experienced longitudinal oscillations called "pogo effect." Had a crew been onboard, they would have experienced severe vibrations and even possible injury.
