This level pretends to enable the making of electrical connections and allow the selection of the best solutions that exist on the market depending on the robot you intend to create. It is also intended to enable people to design 3D parts for the robot's structure. For this, the course explores the core components and strategies for building a high-performing robot. Topics include motor control and driver integration, microcontroller platforms, object transport mechanisms, and the design and fabrication of custom 3D-printed parts. Each unit combines technical insights, practical applications, and decision-making guidance tailored to advanced robotic systems.
