Very nice diagnosis, and it's true, as Dave says, you have to check all the parts connected with the problem. Often, like in medicine, the failure point is a symptom, not the cause. This reminds me of the stuff the guys in Gold Rush on Discovery have to deal with all the time with their second-hand back loaders.
This story is a good example of the fact that often the part that breaks is not the real problem. Sometimes, it's just an innocent bystander. This is important to remember in failure analysis. The impulse is always to focus on the part which broke, and try to find something wrong with it. But it's important to look at the entire mechanical system, rather than just one component in isolation.
I had the same thing happen to my 1985 Toyota Camry (albeit much more expensive). Luckily I was just pulling out from in front of my hour when the car stalled and refused to restart. I had the AAA tow to the local garage where they said the timing belt slipped. They replaced the belt and everything was find for a few months. Then the same thing happened again, this time I was two blocks from home. This time I had it towed to my brother-in-law's garage. The replaced the belt but also replaced both idlers. Never had a problem with the timing belt again. And I never went back to the other garage, either...
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.
