Introduction to robotics

How it started

Following the success of the ESP32 RC boat project, the idea of running a local workshop for younger audiences took shape. The goal was simple: show that robotics and technology are not distant or abstract — they are things you can touch, build, and understand. The local association HLC and the La Cañada town council backed the initiative by providing the venue and helping spread the word.

The projects

Three different projects were on display, each chosen to show a different side of robotics and digital fabrication:

• ESP32 RC boat: the project that sparked the workshop. Participants could handle the boat and understand how an ESP32 microcontroller drives the motors over Bluetooth.
• Servo robot arm: an articulated arm controlled by servo motors that demonstrated the basics of robotics in an accessible, hands-on way.
• 3D-printed hand prosthesis: a functional prosthetic hand made with a 3D printer, which opened a conversation about how maker technology can have a real impact on people's lives.

The experience

The session was dynamic and interactive. The children didn't just observe — they got to engage directly with the projects: moving the robot arm, trying out the boat controls, and seeing how the prosthesis works. Each project was accompanied by a straightforward explanation of the technology behind it.

The response was overwhelmingly positive. The curiosity, questions, and enthusiasm of the participants confirmed that this kind of activity has an important place in local education.

What we learned

In-person workshops are one of the most effective ways to pass on maker culture. Seeing and touching a real project creates an immediate connection that no video or tutorial can replicate. This workshop showed that with well-chosen projects and an approachable presentation, it is possible to spark an interest in technology at any age.
