The era in which artificial intelligence can help teach children has arrived in a Hialeah school.<\/p>\n
Her name is Pepper.<\/p>\n
What began as a grandfather\u2019s dream to build the best possible kindergarten for his first granddaughter has pushed William \u201cBill\u201d De La Sierra to continuously reinvent education. Twenty-four years ago, the real estate developer built the private school KidWorks USA from the ground up. Now he has introduced one of his boldest ideas yet: an AI-assisted robot teacher.<\/p>\n

\u201cWhen AI started to become popular, I said, \u2018Hey, I\u2019ve got to get them excited about artificial intelligence because that\u2019s their future,\u2019\u201d De La Sierra told the Herald. \u201cThey\u2019re going to have to deal with AI. I\u2019m not.\u201d<\/p>\n
KidWorks USA, at 8155 W. 28th Avenue, offers classroom programs from pre\u2011kindergarten through 7th grade and plans to add 8th grade next year. And now, the school is introducing AI to students in an interactive way through a robot that will be able to teach three subjects: science, math and history.<\/p>\n
On Feb. 2, Pepper was introduced to students alongside Hialeah Mayor Bryan Calvo. Rolling into the room, the robot quickly became the center of attention, with students eager to take photos. During a brief, scripted exchange, Calvo spoke with Pepper in English about education and leadership. She said she brings artificial intelligence into the classroom and helps future leaders grow up smart and confident to lead the country.<\/p>\n

Pepper, just one week old at the time, was still developing her software and learning to control her movements, but that did not stop her from showing off some dance moves. She can move her head and arms in a human-like way and is expected to eventually interact with students once she is fully trained. Initially she will teach in English, but she also has the ability to operate in Spanish. A tablet embedded in her torso displays programmed messages. On the day of the presentation, the screen showed the name of the school.<\/p>\n
Pepper\u2019s voice<\/p>\n
Behind the robot\u2019s voice is Kevin Soto, a 24-year-old mechanical engineer with a master\u2019s degree in aerospace engineering and a background in robotics research, who has been a KidWorks counselor for years. He was hired as a consultant to research and develop the AI robotic program for the school, and will train and support their teachers. Soto built the technological infrastructure that will allow Pepper to function as a teacher.<\/p>\n
She is currently being \u201ctaught,\u201d uploaded with all the information she needs to operate as a teacher. Soto said the project to fully operationalize the robot will take about two to three months.<\/p>\n

Pepper has a modular system that allows for extensive customization. While the company that manufactures the robot primarily designs it for instructional purposes, the version being used at KidWorks USA is still being developed and tailored to fit the school\u2019s needs.<\/p>\n
\u201cWe\u2019re adding the features we need for it to be successful in the classroom,\u201d Soto said. The robot can be programmed with speech recognition and text-to-speech capabilities. Because the system operates through downloadable software packages, different language modules can be installed as needed.<\/p>\n
For De La Sierra, the robot is not meant to replace teachers, but to introduce students early to the technologies that will shape their futures. The school already offers a range of hands-on STEM programs, including drone pilot training, robotics, coding, and hydroponics classrooms where students grow strawberries and tomatoes while learning about science and sustainability. It also participates in NASA\u2019s Growing Beyond Earth program<\/a>, which studies plants that could one day become part of astronauts\u2019 food supply during long-term missions in space, giving students opportunities to apply classroom learning to real-world challenges while developing critical thinking, creativity, and technical skills.<\/p>\n The robot, made by RobotLAB a Dallas-based company, currently runs on ChatGPT-based software but could operate on other platforms capable of supporting what developers call API connections. In simple terms, an API allows different software systems to communicate with one another, enabling Pepper to generate lesson plans, answer students\u2019 questions and adapt responses in real time.<\/p>\n De La Sierra said he constantly asks himself what he can bring to his students to better prepare them for the world ahead. His passion for education, first for his granddaughters and now for generations of children in Hialeah, has led him to incorporate hands-on technology into the school\u2019s curriculum. He added he is always bringing refreshing ideas, because that\u2019s what the world is about.<\/p>\n Now, artificial intelligence is the next step. \u201cWe have drone training, we have jujitsu, we have science, we have hydroponics, and now artificial intelligence,\u201d he said. \u201cI\u2019m preparing the kids for the future.\u201d<\/p>\n Captain Pepper represents a $30,000 investment for the school, and De La Sierra is already looking into the possibility of another robot, the Optimus made by Tesla.<\/p>\n \u201cWith the development of AI, we can improve how teaching works, but it\u2019s also important to know that it\u2019s not a replacement for teachers. It\u2019s just a tool.\u201d Soto said. \u201cAnd that\u2019s how it is going to be positioned.\u201d<\/p>\n Privacy, safety concerns<\/p>\n The controversial use of AI technology is raising concerns among educators, who say it could disrupt learning and undermine the emotional development of young children.<\/p>\n Because KidWorks is a private school it is not required to follow the curriculum or guidance of Miami-Dade Public Schools, a lack of oversight that worries some education advocates. Karla Hernandez-Mats, president of Educated We Stand, a nonpartisan organization focused on electing pro-public-education school board candidates, said the absence of clear standards raises questions about how the technology is going to be used and by whom.<\/p>\n Hernandez-Mats, a certified teacher and former president of United Teachers of Dade, added that introducing a humanoid robot into the classroom feels more like \u201ca gimmick for a private school\u201d than a meaningful educational strategy. She said Pepper would be unable to recognize when a child is overwhelmed or in distress.<\/p>\n \u201cA robot cannot teach you how to calm down or show empathy,\u201d she said. \u201cIf a child gets frustrated, how do you detect that? A robot cannot replace a human in that sense.\u201d<\/p>\n While acknowledging that artificial intelligence is increasingly part of education, she emphasized that public schools approach the technology with limits.<\/p>\n \u201cWe teach students how to use AI ethically, as a tool for research, note-taking and learning, not as a replacement for teachers,\u201d she said. Because KidWorks is a private school, it is hard to tell what standards, if any, are guiding the use of this technology, she said. \u201cThere are no guardrails.\u201d<\/p>\n This story was originally published February 20, 2026 at 11:12 AM.<\/p>\n
