The Sherlock Ohms stories never fail to amaze me. I never would have considered adding a ground strap between the wagon body and axle frame. Engineers -- especially those who submit our Sherlock Ohms stories -- are an amazingly clever bunch.
It was good of the vendor to offer a solution to the customer's modification. Good vendors will help as long as safety is not concerned. As a teen, I was working on an old Chevy loosening a bolt that was too close to the frame to reach with a standard box wrench, so I ground some off of the OD which promptly broke. I then took the Craftsman wrench back to Sears who said that it had been modified, but it should have been tough anyway and gave me a replacement.
That is a very interesting story and great job about troubleshooting a field failure with an uncooperative customer...it is also a great reminder to inquire as to any modifications that a customer may have made that can introduce problems that they are blaming on the original design!
Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
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.
