Multi-Axis Kinetic Installation at Sentosa: High-Performance ESP32-S3 Integration

The Challenge: High-Stakes Visual Immersion

For a high-profile permanent installation at Sentosa, Singapore, the client required a kinetic system that could achieve perfect synchronization across multiple moving parts.

The primary hurdles were:

• Latency: Wireless solutions were too interference-prone for a public space.
• Precision: Standard motors lacked the feedback needed for smooth, repeatable "visual immersion."
• Scalability: The system required multiple controllers to work in perfect unison over a dedicated local network.

Our Engineering Approach

We moved beyond standard "maker" solutions to provide an industrial-grade electronics architecture:

Real-Time Reliability (RTOS & ESP32-S3)

We utilized FreeRTOS on the ESP32-S3 to handle multi-tasking. This ensured that motor control pulses remained jitter-free while the controller simultaneously handled background API calls and LED animations.

Hardwired Stability (Ethernet & Static Networking)

To guarantee the lowest possible latency, we bypassed Wi-Fi in favor of Ethernet connectivity. Each controller was configured with a custom static IP, gateway, and subnet, allowing the units to communicate with a central server via API calls with sub-millisecond response times.

Precision Motion (Closed-Loop Steppers)

We implemented closed-loop stepper motors, controlling RPM, speed, and direction with high granularity. Unlike standard steppers, the closed-loop system ensures no steps are lost, maintaining the installation's physical alignment even after thousands of cycles.

Custom PCB & Enclosure Design

The entire system was housed on a custom-designed PCB tailored for the ESP32-S3 ecosystem. We handled the electrical engineering from schematic to fabrication, ensuring the final units were fitted into robust, site-ready enclosures for the Sentosa environment.
