Yes, Nancy, location is everything. a couple months ago there was a discussion about problems with a European car that was not holding up in the desert Southwest. While the car maker was happy to sell cars here, they were not testing their cars for our climate.
I was just in Clovis a couple of weeks ago, Rob. It sure was nice - much cooler during the day and especially in the evenings than Texas at the same temperature. I think Texas humidity is a factor as well. Just goes to show that when you are designing for outdoor environments, there are all kinds of variables that need to be considered! Location, location, location!
Good point on the cold weather, Nancy. It could be that the repetitive swing from hot exposure to cold exposure breaks down the material. So UV resistance may not be enough. In my New Mexico backyard, plastics don't last long. While the temperature may only be 95, the sun beating on the plastic goes to a much higher temp.
Probably so, Rob. The nice thing about our obstacles is that they are portable - they are easy to put up and break down in five minutes or less. If riders store them in their duffle bag out of the sun after using them - they should last for years. I think anything left baking in this heatwave will eventually have an effect. Same problem leaving them out in cold weather - pvc is known to get brittle.
I agree Rob, I really like Flow-Rite's innovation and careful consideration of both environmental factors and seeking ways to error proof connections. The Texas sun is brutal as well - I am wondering how long one can expect the UV protection to hold up and what the specs are for that type of testing...we have UV protected furniture grade pvc pipe for some of our horse obstacles to protect against degradation but extended exposure will eventually have some effect. Of course horse obstacles aren't made to withstand acid so I am guessing these couplers are pretty tough in comparison.
I also really like their ease of use - it is so nice to be able to carry out a task without having to wrestle with the connectors first!
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.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
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.
