One Robot Changes Tires. Another Danced On A Runway. Which Is A Business?

Robots were in the news a lot this week. Three stories stood out, and put side by side, they teach one of the most important ideas in business.

Robot one changes car tires. A San Francisco startup called PitPro installed its first tire-changing robot at a tire shop in Calgary, Canada. The company says it can swap all four tires on a car in under 15 minutes.

Robot two tightens bolts on big pipes. A startup called Nexterity built a small robot that loosens and tightens the heavy bolts holding pipes together in factories and plants. It was picked as one of 200 startups to show off at TechCrunch Disrupt in October.

Robot three danced. At Vogue World, a big fashion show in Milan, humanoid robots walked out, waved their arms and asked the crowd to clap. TechCrunch reported that many people were not impressed.

All three are impressive machines. Only some of them are solving a problem someone will pay for. Let's figure out which, and why.

Changing tires is hard, heavy work. PitPro's founder, Jeremy Conrad, told TechCrunch that tire shops have trouble finding and keeping workers. Many new hires leave within a few months to a year.

He shared a story from one shop manager. When a fast food restaurant opened across the street, about half the shop's workers left to work there instead. The shop had to get special permission to raise pay.

Now add Canada's weather. In many parts of Canada, drivers switch to winter tires every fall and back again every spring. That means shops get a huge rush of the same job twice a year.

So the problem looks like this:

• The job is physically tiring.
• It is hard to hire enough people.
• The same task repeats thousands of times.
• Demand spikes at predictable times.

That is a strong setup for a robot. PitPro's system is two machines about the size of an oven that fit into a normal repair bay. They find the lug nuts, remove the wheels and put new ones on.

Nexterity's founder, Lindsey Elliott, used to be an engineer at a large energy company. She spent years around the pipes that carry oil, gas, water and chemicals.

Those pipes are joined together with heavy bolts. Loosening and tightening them takes a lot of force, and it is a common source of injuries for pipefitters, the workers who do the job. Elliott told TechCrunch that crews sometimes work 12 hour days for months in a row, and there are not enough workers.

Then she found a clue. By talking to experts, she learned that about 80 percent of pipes are in a small range of sizes, between two and eight inches wide. When the same task happens over and over at the same few sizes, it becomes a great job for a machine.

Her robot fits around a pipe, runs on batteries and handles four bolts at once. It is small enough to fit in a carrying case, so one worker can bring it to a job site. Nexterity plans to rent the robots out, the same way construction companies rent other equipment.

The dancing robots at Vogue World were real, working machines made by a company called Unitree. So why the cold reaction?

TechCrunch reported a few reasons. The show was supposed to celebrate human craftsmanship, so robots felt out of place. Some people felt uneasy about robots and jobs. And one founder asked a simple question: what were the robots even modeling?

That question is the key. The robots were not solving a problem for the audience or for the designers. They were there to be surprising. Surprise gets attention for a moment, but it does not usually turn into a business on its own.

To be fair, entertainment robots can be a real business. People pay for shows, toys and games. The lesson is not "fun robots are bad." It is that every product needs a clear answer to "who needs this, and why?"

Engineers often use a simple rule for deciding what robots should do. Look for jobs that are dull, dirty or dangerous.

• Dull means the same motion repeated again and again. Tire changes and bolt tightening both qualify.
• Dirty means messy, dusty or unpleasant conditions. PitPro had to design for shop bays with open doors, dust and weather. The team even found its robots covered in dandelion seeds.
• Dangerous means people can get hurt. Heavy bolts on pipes are a common cause of injuries.

A good robot idea usually hits at least two of the three. Then add two business questions:

1. Is someone already paying for this job? Tire shops and pipe crews already pay workers. A robot that helps them saves money they are already spending.
2. Does the task repeat the same way many times? Robots are best at jobs that look alike each time.

Try it on the runway robots. Dull? No. Dirty? No. Dangerous? No. Someone paying for a solution? Not clearly. That is why they felt like a show, not a business.

Time to be an inventor. This works for ages 8 and up, alone or with a group.

Step 1: Hunt for tasks (15 minutes). Walk around your home, school or a family member's workplace. List ten jobs people do. Include chores, like folding laundry or taking out trash, and work tasks you have seen.

Step 2: Score each job. Give one point each for dull, dirty and dangerous. Give another point if someone already pays for it, and one more if it repeats the same way. The top score is five.

Step 3: Pick your winner. Choose the task with the highest score.

Step 4: Sketch the robot. Draw what it looks like, how big it is and how it moves. Label the parts. Where does the power come from? How does it know where to go?

Step 5: Make a model. Use cardboard, tape, craft sticks or building bricks. It does not have to move. It has to show the idea.

Step 6: Answer the business questions. Who would buy or rent it? How much do they spend on this job now? Would they rather buy it or rent it, like Nexterity's customers?

When your robot design is done, you can use the planning lessons on Foundra Kids to write a one page pitch for it.

Some kids worry that robots will take everyone's jobs. It is a fair question, and the robot stories above show both sides.

Both PitPro and Nexterity describe their robots as help for workers, not replacements. The tasks they automate are the hardest on people's bodies, and both industries have more work than workers. A pipefitter with a bolt robot can spend less energy on the heaviest lifting and more on the parts of the job that need judgment.

At the same time, the reaction at Vogue World shows that many people feel uneasy about machines replacing human skill and creativity. Those feelings are real and worth talking about.

A good family discussion question: "If you could hand one part of your day to a robot, which part would you keep for yourself, and why?"

Do kids need to know coding to design robots? No. Designing starts with finding the right problem and sketching a solution. Coding and electronics can come later through clubs, kits or classes.

What is TechCrunch Startup Battlefield? A competition where 200 early stage startups from around the world are selected to exhibit at TechCrunch Disrupt. Nexterity is one of them this year, along with robotics startups working on things like snow removal and mosquito control.

Why would a company rent a robot instead of buying it? Renting costs less upfront, and job sites change often. Construction companies already rent many tools this way.

Are robots going to replace tire technicians? Not soon. PitPro's robots handle the heavy removal and installation steps, and shop staff still run the bay and do other repairs.

What is a good first robotics project for kids? Start with the design challenge above. Then try a beginner robotics kit or a school club where you can build something that moves.
