We are on the cusp of a transportation revolution. From the warehouse to the consumer's converting transportation needs, change is afoot. For years, this has been a labor-intensive area with tremendous capital investment. This is rapidly changing. I thought I would start out this month by relating my personal experience in one area of rapidly changing transportation--lawnmowing.

We live on a pie shaped lot on a cul-de-sac. The front is 25 feet wide, and the rear is 250 feet wide. That is measured at the top of a bank that drops off to a creek. The bank is covered with pachysandra and is not mowed, nor is any part at the water's edge mowed. The front yard is flat, and the sides drop down by one floor, so the basement exit is at the back yard level. The back yard is flat from side to side as well.

Six years ago, I bought a Husqvarna Robotic Mower ($4,500), encapsulated by a buried wire, much like a dog fence. The mower had no particular path; it just ran around inside of the wire boundary. It was acceptable in mowing and time of mowing. It used blades that look half the length of old-fashioned safety razor blades (I have since found out these are the blades of choice for all robotic mowers, at least all the ones I have experienced). This mower was OK, but after a while the boundary wire would break, and I spent a lot of time looking for the breaks.

The wire breaks reminded me of an autonomous cart system we had at the Procter & Gamble diaper plant in Cape Girardeau, Missouri fifty years ago. These carts followed a wire buried in the cement floor which was prone to breakage at the slab joints.

A couple of years ago, I bought a Mammotion Robotic Mower ($3,000+). This mower did not have a wire boundary. It was guided by 33 satellites (I kid you not) which triangulated off an RTK (Real-Time Kinematic) stationary antenna. I suspect this would work fine in an open area, but with trees around, it was a disaster. It had to detect all 33 satellites, or it would not move.

This spring, the number of robotic mower brands available has blossomed to close to a dozen or more. I don't walk so well any longer, so this method of cutting grass has become critical unless I want pay $250/month, the going rate here. I went to ChatGPT and did my research. I bought a Segway I250 ($1,300 on sale at Home Depot). This mower is guided by Lidar (Light Detection and Ranging) and works beautifully. ChatGPT recommended this brand because of Segway's experience in electronic drives (remember their scooter?). It actually gave me the choice of another brand, as well, but pointed out that company did not have the experience of Segway.

I think other advanced transportation systems are developing in a parallel path to these mowers. We will examine in the balance of the month.

Be safe and we will talk next week.

__________

Part II: Quiz Answer Key

1. The transportation shift: The author identifies that we are on the cusp of a "transportation revolution" moving away from labor-intensive areas requiring massive capital investment. This change is occurring across the industry, from warehouse logistics to individual consumer needs.
2. Property layout: The lot is pie-shaped, measuring 25 feet wide at the front and 250 feet wide at the rear, featuring a bank that drops off to a creek. The terrain includes flat areas in the front and back, but a one-floor drop on the sides, making automated maintenance a complex task.
3. Husqvarna limitations: The Husqvarna mower relied on a buried boundary wire similar to a dog fence and followed no particular path within that boundary. Its primary drawback was the frequent breaking of the wire, which required significant time and effort to locate and repair.
4. Historical parallel: The author compares the wire-guided Husqvarna mower to autonomous carts used at a Procter & Gamble diaper plant in Missouri fifty years ago. Those industrial carts followed wires buried in cement that were prone to breaking at slab joints, much like modern residential wire boundaries.
5. Mammotion guidance and failure: The Mammotion mower utilized Real-Time Kinematic (RTK) technology, triangulating its position from a stationary antenna and 33 satellites. It failed in the author's yard because the system required a connection to all 33 satellites to move, which was impossible due to the presence of trees.
6. Segway recommendation: ChatGPT recommended Segway because of the company's extensive established experience in electronic drives, specifically citing their history with scooters. While other brands were available, ChatGPT noted they lacked the specific engineering experience possessed by Segway.
7. Economic motivations: The author notes that he has difficulty walking, making manual labor difficult, and the alternative cost of hiring a mowing service is $250 per month. By purchasing a mower like the Segway I250 for $1,300, the technology becomes a cost-effective long-term solution.
8. Navigation technology difference: While the Mammotion mower relied on satellite triangulation and an RTK antenna, the Segway I250 utilizes Lidar (Light Detection and Ranging). This allows the Segway to function "beautifully" without the satellite connectivity issues that plagued the Mammotion model.
9. Robotic mower blades: The author observes that robotic mowers use blades that resemble roughly half the length of "old-fashioned safety razor blades." He notes that these specific blades appear to be the industry standard for all robotic mowers he has encountered.
10. Broader significance: The author views the rapid development and blossoming of robotic mower brands as a "parallel path" to other advanced transportation systems. He suggests that the innovations seen in residential lawn care are indicative of the wider changes occurring in the transportation revolution.

Part III: Essay Format Questions

Instructions: Use the source context to develop comprehensive responses to the following prompts. (Answers not provided).

1. Comparative Analysis of Navigation Technologies: Evaluate the progression from buried wire systems to satellite-based RTK and Lidar. Discuss the environmental factors that determine the success or failure of each system based on the author's experience.
2. The Economics of Automation: Discuss the financial trade-offs between capital investment in autonomous machinery and recurring labor costs. Use the price points of the Husqvarna, Mammotion, and Segway models to support your analysis.
3. The Role of Artificial Intelligence in Consumer Research: Analyze how the author utilized AI (ChatGPT) to navigate a "blossoming" market of close to a dozen brands. What does this suggest about the future of purchasing complex technical equipment?
4. Reliability and Maintenance in Autonomous Systems: Examine the recurring theme of "breakage" and system failure in the text. Contrast the physical maintenance of the Husqvarna's wire system with the connectivity requirements of the Mammotion's satellite system.
5. Technological Continuity over Time: Explore the author's observation that autonomous cart technology from fifty years ago shares fundamental similarities with modern robotic mowers. How does this reflect the nature of engineering evolution?
