3.1 Cable Management
- Improve and organize cable routing from the initial setup stage.
- Establish a systematic layout to reduce installation time and prevent cable interference.
- Clearly separate power, signal, and control cables where practical.
01 / Overview
Purpose of this report
This report summarizes the proposed hardware, software, control, and ventilation improvements for the NaoDec equipment following the Cloud 11 exhibition in Bangkok.
The main focus is to improve cable management and system connectivity, vibration and noise reduction, odor/scent ventilation, internal Edge LED reliability, control functionality and synchronization, and system monitoring and operational logging.

03 / Hardware & Connectivity
Make installation robust by design
3.2 Chamber & Controller Connection
- Increase the distance between the Chamber and the controller.
- Use longer LAN, USB-C, and HDMI cables (~5 m) for placement flexibility.
- Provide sufficient length without excessive tension or sharp bending.
3.3 Vibration & Noise Reduction
- Add foam foot pads or vibration-absorbing pads underneath chair/platform contact points.
- Reduce impact noise and vibration when the chair contacts the floor.
- Evaluate damping materials during the next installation.
3.4 Speaker Installation
- Consider installing speakers directly into the headrest.
- Reduce cable-routing complexity and simplify installation.
- Evaluate placement, acoustic performance, and maintenance accessibility before implementation.
3.5 Vertex Unit Cable
- Change the Vertex unit cable from a 4-pin ribbon cable to a 5-pin cable.
- Integrate coil power into the main cable.
- Simplify cable management and reduce separate connections.
3.6 Internal Edge LED Reliability
- Protect and secure solder joints at both ends of each T8 LED tube.
- Prevent mechanical stress and intermittent electrical connections.
- Address glitches, flickering, or intermittent operation in the first and last LEDs on each tube.
- Add mechanical protection and strain relief for long-term reliability.
04 / Software & Control
Bring systems into sync
4.1 Lighting Control
- Add brightness adjustment for the lighting system.
- Provide flexible lighting intensity control for different demonstration sequences.
4.2 Odor/Scent Control
- Add a control-system function to stop odor/scent emission.
- Allow independent scent-system shutdown when required.
- Integrate it with demonstration sequences and emergency/manual controls.
4.3 Data Synchronization
- Develop a feedback system that sends status information to the main control software.
- Accurately reflect the current status of connected hardware.
- Improve coordination between hardware actions and software commands.
4.4 System Logging
- Add comprehensive usage and operation logging.
- Record events, commands, errors, and hardware status.
- Enable retrospective analysis and distinguish software from hardware failures.
05 / Immediate Issues & Ventilation
Resolve open concerns
5.1 GAB8 Amplifier Status LED
- Investigate the yellow status LED on the GAB8 amplifier daughterboard.
- Determine whether it indicates normal operation, a warning, protection mode, or a hardware issue.
- Verify amplifier operation and its cooling system.
5.2 Odor/Scent Ventilation
- Install additional fans to extract residual scent from the platform after each session.
- Activate fans automatically when the session ends.
- Set a ventilation duration that clears scent before the next session.
- Ensure the system does not interfere with equipment or the intended experience.
06 / Recommended Development Priorities
Prioritize the highest-value changes
| Priority | Improvement | Objective |
|---|---|---|
| High | Edge LED solder-joint protection | Prevent first/last LED glitches and improve reliability |
| High | Odor/Scent Ventilation | Remove residual scent between demonstration sessions |
| High | Cable Management | Reduce setup complexity and prevent connection issues |
| High | System Logging | Improve troubleshooting and failure analysis |
| Medium | Data Synchronization | Improve hardware/software status feedback |
| Medium | Odor/Scent Control | Improve control over scent emission |
| Medium | Vibration Isolation | Reduce noise and structural vibration |
| Medium | Vertex 5-pin Cable | Simplify cable and coil power connections |
| Low / Med. | Headrest Speaker | Simplify speaker cable routing |
07 / Conclusion
Next development phase
The next development phase should focus on improving system reliability, installation efficiency, operational control, and user experience.
The immediate priorities are Edge LED reliability, odor/scent ventilation, cable management, and system logging, as these directly address issues observed during the Cloud 11 exhibition.
The proposed hardware and software changes should be tested together during the next assembly to verify system stability and ensure that improvements in one subsystem do not introduce new issues in other parts of the NaoDec system.
