The robot named Frank was assembled with scrap parts by a street vendor who works on the beaches of Praia Grande and now pulls the popcorn cart by himself while emitting sounds and talking to bathers, attracting crowds along the São Paulo coast
A robot built entirely from scrap motorcycle, scooter, and washing machine parts is attracting attention on the beaches of Praia Grande, on the coast of São Paulo. The inventor is Ed, a street vendor who created the machine named Frank to pull his popcorn cart through the sand, making daily work easier and turning sales into a spectacle.
According to a report from Balanço Geral, Frank is not just a traction assistant. The robot emits sounds, reproduces phrases, and interacts with customers on the beach, functioning as an attraction that draws curious onlookers and buyers at the same time. The result is that a simple street vendor from Praia Grande has become a well-known figure on the coast, proving that creativity and necessity can generate inventions that no factory ever imagined.
From welder to inventor: how Ed learned to bring scrap to life
Ed’s story with inventions began in childhood. As a child, he would take cans and pieces of wire to build little cars, airplanes, and even miniature tanks, demonstrating a manual skill that caught attention at school science fairs.

China is testing a train that will operate at 400 km/h in daily service, which is 80 km/h faster than the French TGV, and uses carbon fiber, magnesium alloys, and more than 4,000 sensors to become the fastest commercial train on the planet.
As an adult, Ed worked as a welder, and it was in this trade that he learned the necessary techniques to join, repair, and shape materials that others discarded.
What many people saw as trash, Ed saw as potential to transform into technology.
This combination of natural talent with professional experience created the foundation for the street vendor from Praia Grande to become an inventor capable of building a functional robot from scrap.
Frank, the scrap robot that pulls the popcorn cart on the sand
The great inventive leap for Ed happened when he started working as a street vendor on the beaches of Praia Grande.
Dragging a popcorn cart through the sand every day is physically exhausting, and it was precisely this difficulty that motivated the creation of Frank.
The robot was assembled with a motorcycle channel, an old scooter motor, a refrigeration motor, and washing machine parts.
Each scrap component gained a new function within Frank’s structure, which today autonomously pulls the popcorn cart along the sandy path. The visual inspiration came from the cartoon Woody Woodpecker, which gives the robot a fun appearance that especially captivates children at the beach.
A robot that sells popcorn and talks to customers
Frank is not limited to pulling the popcorn cart. The robot emits sounds and reproduces phrases like “look at the popcorn, we have sweet, we have salty” and “who wants some? I am Frank”, turning the sales approach into entertainment for those passing by on the beach.
This interaction with the public completely changed Ed’s sales dynamics.
Bathers stop to film, children approach curiously, and the popcorn cart ends up selling more precisely because the robot acts as an attention magnet.
The street vendor who once competed for customers with dozens of other workers on the beach now has an advantage that no one can replicate: a robot made of scrap that turns each sale into a small show.
Creativity from Praia Grande that went viral on the São Paulo coast
Ed and Frank’s fame has already surpassed the sands of Praia Grande. The story of the street vendor who created a scrap robot to pull his popcorn cart went viral on social media, attracting the attention of locals and tourists who make a point of finding Ed on the beach to see Frank in action.
Ed’s case is an example of how practical necessity can generate innovation outside of laboratories and large companies.
With parts that would cost cents at a junkyard, a worker from Praia Grande built a machine that solves a real problem, entertains the public, and increases his sales.
No engineering course or funding was needed: just the same curiosity that, in childhood, turned cans into little airplanes.
Have you seen any invention like this in your city?
Ed proved that talent and scrap can be transformed into something that no assembly line would produce.
The robot Frank pulls the popcorn cart, entertains customers, and gave the street vendor from Praia Grande a unique identity on the São Paulo coast.
And you, have you encountered any inventor like this at your beach or in your city? Do you know someone who transforms what would be trash into a working tool? Share in the comments the most creative story you have ever seen.
