Ondrives Ltd. added to their range of HTD
pulleys and belts with a 3 mm pitch version. The 3 mm pitch HTD pulleys are
made to suit 9 and 15mm corresponding belts as standard. There are 3 different executions of pulleys
available depending on the number of teeth required. All are aluminium with one
version being plain and the other two manufactured with zinc plated steel
flanges. Numbers of teeth available vary from 10 up to 72 and different numbers
of teeth as well as other modifications are also available upon special
request. 3 mm HTD belts are available with the pulleys and belt lengths start
at 105 going up to 1863 mm. The belts are manufactured from rubber back/teeth
and are glass fibre reinforced, with a nylon fabric tooth facing to DIN/ISO
5296. The rest of the HTD range includes 5, 8 and 14 mm pitch.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
