KISS — Keep It Simple Stupid
Early in my career I was assigned the task of commissioning an $70,000 electric paint robot. Unfortunately at that stage of robot evolution, the seal design at the robot joints prevented it from painting more than the first part. The vapors shorted it out. What I learned is that it is more effective to tackle automating the simplest tasks first. Simple tasks take less investment to automate. Even though modern 6 axis robots can now handle painting tasks, combining them with required sophisticated guard enclosures places them far from the KISS category in my mind.
I was watching a 2 axis gantry “robot” carry engine cylinder heads at a Honda assembly plant in Alabama. Reminded me of a dog playing fetch with a stick. The jaws of the gripper opened and the human at the end was presented with the retrieved cylinder head. I install gantry robot transport systems for the same benefit, their simple motion and guards allow humans to safely work along side them. These robots do not care that I am comparing them to a dog. As Ada Lovelace wrote as her work began the digital age “The Analytical Engine has no pretensions whatever to originate anything. It can do whatever we know how to order it to perform”

Kiva robots are even simpler. They race to the other end of the warehouse and wait like puppy dogs for us to collect the item they have retrieved. All of this without the clutter of the rails and guards of gantry retrieval systems.
Moore’s law marches on. The cost of computers has dropped to the point where we can afford to automate even simple tasks. It is easy to write down date, starting odometer, location, finishing odometer and purpose for one business trip. You get pissed off enough to invent a better way when you spend a chunk of every Christmas vacation inputting a list of a thousand or so business trips so that you qualify to keep the $8000 to $9000 dollar business mileage deduction. I want to use the KISS principle to fix all the aggravations in my life.

I have to admit that many years of installing robots to reduce labor has blinded me into thinking of automation as robots to be installed. This matched the marketplace because the $200,000 robots morphed into $50,000 robots opening the door for new applications with each price drop. Shop floor manufacturing cost which was $.50 of every sales dollar in the 1950’s has steadily declined to $.20 of every sales dollar today. Since 80% of the current business costs are not on the manufacturing floor, it is not surprising that the best opportunities for reducing cost by automating are no longer on the shop floor.
It would be naive to claim that no automating activity has occurred off the shop floor. The PC, then smart phone revolutions, have brought the efficiency of software to our fingertips. We would not even consider typing and mailing a letter anymore. PC Office suite software is now available as “free” open source downloads. The more recent smartphone market is equally mature. Even as early as 2010, 90% of the smart phone apps sold less than 100,000 copies, which suggests that they failed to cover their development costs.
The 80% share of business cost off the shop floor shows that the current opportunities are still away from the shop floor. The developers agree and the latest excitement is centered around innovations that combine software and hardware. This is consistent with what I am seeing. Somewhere in the future your cars will have enough connectivity and spare computers or your cell phone will have enough battery capacity to handle extra tasks. In the short term dedicated devices such as the mileage trakker http://mileagetrakker.com that I market are good examples of the latest trend. Business people who travel are happy that a device plugged into the car handles most of the assembly of an IRS format mileage report so that they can receive their significant mileage deduction at income tax time
