episode 1 the journey
From technical diagrams to adventure maps / De diagramas técnicos a mapas de aventura
Felipe and ORION present a technical diagram outlining how to make the vambrace a reality. However, David interrupts—the diagram is too rigid and uninviting for people to engage with. He refactors it into a vibrant, illustrated adventure map inspired by Doctor Stone. Now the journey is clear and exciting: from component preparation to final testing, every step becomes part of an epic quest to build the teleoperation vambrace.
Technical documentation doesn't have to be intimidating. By transforming cold diagrams into visual narratives, we make knowledge accessible to everyone—from engineers to curious minds just starting their robotics journey. The same information can inspire or overwhelm depending on how it's presented.
-
Design bridges understanding: A well-designed visual can communicate complex ideas faster and more effectively than text alone. David's illustrated map doesn't remove the technical depth—it makes it inviting.
-
Collaboration improves outcomes: Felipe's engineering rigor provided the structure, David's design thinking made it approachable, and together they created something better than either could alone.
-
The journey is the destination: Breaking down a big project into clear stages makes it less overwhelming and more achievable. Each milestone becomes a mini-adventure.
-
Refactoring isn't just for code: Ideas, designs, and plans can all be refactored to better serve their purpose. What works in one context might need re-imagining in another.
The adventure unfolds in these stages:
- 🔧 Prepare Components - Gather and test all hardware elements
- 🤖 Create ROS 2 Node on ESP32 - Start the µ-ROS application on the micro-controller.
- 🕹️ Add Joystick for Teleoperation - Implement movement control
- 🎛️ Include Potentiometers for Arm Control - Enable an easy way to move the 1DoF arms.
- ⌨️ Use Membrane Keyboard - Program default emotions and actions
- 🔗 Perform Integration - Connect all components into a unified system
- 🧪 Technical Testing - Validate functionality and reliability
- 👥 User Testing - Real-world feedback and iteration
- 🎨 Design the Vambrace - Create an ergonomic, aesthetic enclosure.
- 🔨 Build It - Physical assembly and construction
- ✅ Test It - Final validation with ORION
"Well, it is a simple workflow..." - Felipe "It is a good draft, but we can do something better..." - David
The roadmap is clear and beautiful, it gives us a better preview of the problem. But how will all these components actually talk to each other? How does the ESP32 send commands to ORION? The next chapter reveals the communication architecture that makes everything possible.
➡️ Episode 2: The Comms / Las Comunicaciones
Danna, Felipe, and David explain ROS 2 topics—the publishers and subscribers that connect velocity, arm control, display, and voice throughout the vambrace system.
