Robot vacuums are starting to grow "hands." At the 2025 AWE and CES exhibitions, the Dreame 4-joint bionic manipulator and the Roborock G30 Space Explorer Edition 5-axis folding manipulator made stunning debuts, marking their entry into the era of "Embodied AI." How do these "hands," capable of gripping 400-gram objects and performing precise operations within 30 centimeters, operate stably? FOSAN reveals the secret: the solution from Fuxin Semiconductor, part of the FOSAN Group, is the key enabler behind these innovative functions.
Power Management System: The Foundation of Stable Electricity
The IC integrated circuits from Fuxin Semiconductor form the "power hub" of the robot vacuum. Models like the FS1117-adj and FS1117-3.3 accurately convert battery voltage into the stable voltages required by the main control chip and sensors, ensuring stable operation of all components and providing the power foundation for the manipulator's complex movements.
Motor Drive System: The Source of Powerful Motion
Fuxin Semiconductor's series of MOS tubes provide the core driving force for the manipulator's joints and movement mechanisms.
For motor driving, the recommended N-MOS tube FS3400M plays a key role. With a drain-source voltage of 30V and a continuous drain current of up to 5.8A, it offers excellent gate turn-on voltage characteristics and can quickly respond to drive signals, fully meeting the driving needs of the manipulator's joint motors and the robot vacuum's movement motors under various operating conditions.
When the manipulator grips objects, this MOS tube keeps switching losses at a low level. Compared to traditional components, energy consumption is significantly reduced, allowing the robot vacuum to complete more cleaning tasks on the same battery charge, effectively improving work efficiency and battery life.
ESD Protection and Signal Processing: Ensuring Stable Operation
In electrostatic discharge (ESD) protection, Fuxin Semiconductor's TVS tube SMF26CA plays a pivotal role, building a solid "protective barrier" for the circuit system. Its reverse stand-off voltage performance is excellent. When encountering electrostatic shocks, it can rapidly release the electrostatic energy, effectively protecting components highly sensitive to ESD, such as LiDAR and ToF sensors. It's crucial to note that if these components suffer from electrostatic interference, sensor data can become erroneous, components can be damaged, and the manipulator's action accuracy can be severely affected.
In the signal processing stage, Fuxin Semiconductor's FRH high-precision resistor series (accuracy ±0.1%, temperature drift ±10ppm/℃) are used for LiDAR signal conditioning, precisely controlling distance measurement errors within 2mm. The voltage regulator diode BZT52C27 provides a stable 27V±2% voltage for the ToF sensor, ensuring high-precision positioning of the manipulator within its working range. These components work in synergy, enabling robot vacuums equipped with manipulators to accurately identify targets like slippers and paper balls, plan grasping paths correctly, and effectively avoid issues like mis-grasping.
Technology Adaptation: Supporting Industry Innovation
The current "manipulator revolution" in robot vacuums places new demands on semiconductor components, such as miniaturization, low power consumption, and fast response. FOSAN actively responds by reducing component package sizes to fit the compact internal space of robots, using advanced processes to lower standby power consumption and increase switching speed to meet the needs of the manipulator's rapid movements. Components from Fuxin Semiconductor already deliver core value by improving action precision, reducing energy consumption, and enhancing reliability, driving the evolution of robot vacuums from floor cleaners to home service robots.
As manipulator technology upgrades towards higher degrees of freedom and greater load capacity, Fuxin Semiconductor has simultaneously developed a new generation of more suitable components, continuously providing device-level solutions for industry innovation, helping "handy" robot vacuums truly enter millions of households.
As a core part of the FOSAN Group, Fuxin Semiconductor adheres to the philosophy of "driving product evolution through component innovation," infusing automotive-grade quality standards into the consumer electronics field. Its comprehensive technology portfolio, from power management to motor drive, not only supports robot vacuums advancing towards new "Embodied AI" forms but also demonstrates the core strength of Chinese semiconductor companies in the field of smart home core components, providing solid localized technical support for industry upgrading.
