• Moore's Law has long applied to advancements in technology-based industries. Servo- and Automation have benefited particularly from exponential advancements in memory as well as processing power, and most recently, astounding gains in sensor technology performance vs. price.  Here is one definition of a servo system that I will use to limit the scope of what I share in this and future blog posts.

  • In my last blog post, I discussed drive-by-wire in a car. Essentially, the mechanical linkage between you and the steering wheel clutched in your white-knuckled fists is going away-replaced by sensors on the steering wheel that tell an actuator motor which way, how hard, and how far to turn the car's wheels based on how far and how hard you are turning the steering wheel. Let's turn the concept inside out now. Suppose instead of wheels, a machine was holding surgical needle and thread. Or a camera. Or a scalpel. Or a stent.

  • Although my blog entries will generally call attention to new ideas we think will end up someday on the factory floor, drive-by-wire actually lags industry: this type of following, such as electronic gearing (a.k.a. cam profiling or camming), has been available in Industrial Automation for years.
