BIWIN Embedded Storage for Robot Vacuums

Overview

As one of the most popular products in the smart home sector, robotic vacuums have entered millions of households worldwide. Storage solutions for robotic vacuums cover critical aspects such as data recording and garbage collection, directly shaping both the user experience. While facing multiple challenges, innovations like high-capacity memory chips and advanced algorithms enable smoother performance, greater efficiency, and higher reliability.

Requirements

Real-Time Perception in Complex Home Environments: Multiple obstacles and surface types demand high-speed read/write performance to support real-time sensor fusion and computation.
Long-Term Reliable Recording: Maps, routes, and logs require continuous, concurrent writes with zero tolerance for data loss.
Serviceability & Cost Control: The complex environment makes troubleshooting difficult for end users, increasing the cost of individual service events.

Highlights

Real-Time Bandwidth: Memory supports concurrent high-speed read/write and caching for vision, LiDAR, odometry, and path-planning data streams.
Low Power Consumption: Low-voltage I/O combined with system-level power-saving strategies reduces power consumption in both standby and active modes, extending cleaning cycles and battery life.
Wide Temperature Range: Reliable operation from -25°C to +85°C, covering typical indoor and edge conditions.
Data Integrity: Firmware integrates ECC, validation, and recovery mechanisms to ensure long-term data accuracy and system stability.
