Robots Makers en Acción

Build your first explorer robot

The course where the educational robot was born: an explorer built from scratch, programmed in Arduino and controlled over Wi-Fi, with parts 3D printed by the students themselves.

Robots Makers en Acción

This is the course that changed the next three. To teach robotics without depending on expensive, closed commercial kits, Elvis Andrade and I designed and built our own educational robot: chassis, electronics, an H-bridge for motor control and firmware with Wi-Fi control from the browser.

On that foundation, students do not assemble a kit by following instructions: they build their robot from scratch, program it in the Arduino IDE and design in Tinkercad the parts they need (arms, grippers, mounts) so their explorer can solve the mission they defined themselves.

The first half of the semester keeps the structure of possible futures and everyday problems; the second turns entirely to the robot, programming and prototyping, up to the final learning fair that brings together every course in the program.

Educational robot developed for this course

Together with Elvis Andrade we created our own educational robot to teach this course: frame, electronics, Wi-Fi control and printable parts. The same robot later became the base of Misión Espacial and Robot Espacial.
