Key IC selection
main controller and wireless SoC
- Need: Dual-core processing, Wi-Fi/BLE connectivity, rich GPIOs for motor PWM, encoder inputs, and I2C/SPI sensor interfaces.
- Class: Wi-Fi/BLE enabled 32-bit Microcontroller SoC
- Shortlist: Espressif ESP32-WROOM-32, Realtek Ameba series
- Pick: Select module variant with appropriate flash size (e.g., 16MB) based on OTA firmware and SLAM local map caching requirements.
power input and charging interface
- Need: Standardized high-voltage/high-current DC power input port for charging system batteries and powering internal rails.
- Class: USB Type-C Power Delivery (PD) Receptacle with ESD protection
- Shortlist: Amphenol USB-C receptacle, Molex high-durability USB-C
- Pick: Choose a robust, mechanically anchored mid-mount USB-C connector rated for high insertion cycles and supporting USB PD up to 20V.
Risk register
| ID | Area | Severity | Detail | Mitigation |
|---|---|---|---|---|
| r1 | firmware | high | ESP32-WROOM-32 lacks the RAM and compute power required to run heavy SLAM mapping algorithms and real-time 6-axis arm kinematics concurrently. | Offload high-level SLAM and arm trajectory planning to an external companion processor (e.g., Linux-based SoC) and use the ESP32 strictly as a real-time I/O and communication co-processor. |
| r2 | power | high | Powering high-torque stair-climbing actuators and vacuum motors via a system architecture dependent on a USB-C Power Jack will cause severe voltage sags and brownouts on the 3.3V MCU rail. | Isolate the high-power motor rails directly from the main battery pack with dedicated high-current power paths, utilizing heavy bulk capacitance and robust DC-DC buck regulators. |
| r3 | emi | med | High-frequency switching noise from multiple brushed/brushless motor drivers for the arm and climbing tracks will interfere with the ESP32's onboard Wi-Fi antenna, causing dropped cloud telemetry packets. | Ensure strict PCB layout separation between high-current motor traces and RF sections, use solid ground planes, and add adequate decoupling and common-mode chokes on motor lines. |
