| Concept | Date | Proposed | R/D | Description |
|---|---|---|---|---|
| Function | 22/02/2025 | I+C | R | Design and build an interactive sponge puppet with a movement mechanism synchronized with voice to enhance storytelling. |
| Dimensions | 22/02/2025 | I | R | Height: 30 cm, Width: 20 cm, Depth: 15 cm. Approximate weight: 500 grams. |
| Movements | 22/02/2025 | I | R | Opening and closing of the mouth synchronized with voice. Basic facial expressions. |
| Forces | 22/03/2025 | I | R | The servo motors apply the necessary force to move the mouth and generate expressions without compromising the structural integrity of the puppet. |
| Energy | 22/03/2025 | I | R | Powered by a rechargeable 7.4V LiPo battery or USB connection. |
| Materials | 22/03/2025 | I | R | Flexible sponge for structure, PLA or ABS 3D printed internal components, Arduino control system. |
| Signals and Control | 22/03/2025 | I | R | Input: Microphone for voice detection. Output: Servo motor control with real-time synchronization. |
| Manufacturing and Assembly | 22/04/2025 | I | D | Sponge cutting, 3D printing, electronic integration, and programming. |
| Transport and Distribution | 22/04/2025 | I | R | Designed for compact packaging with protection against impact and moisture. |
| Lifespan and Maintenance | 22/04/2025 | M | R | Estimated lifespan of 2 to 3 years with easy maintenance access. |
| Reliability | 22/05/2025 | I | R | Minimal error rate in voice synchronization and movement. |
| Costs and Deadlines | 22/05/2025 | I+C | R | Estimated manufacturing cost between 650 and 700 USD. |
