Patrol Robot Controller Board
Patrol Robot Controller PCBA – Smart Patrol Robot Control Board | Source Factory Direct | Customization & Wholesale Available

Our Patrol Robot Controller PCBA supports dual‑channel BLDC hub motors (or DC geared motors) with FOC drive, achieving high‑precision speed and steering control. It integrates multiple sensor interfaces for LiDAR, vision cameras, infrared detection, rain/light sensors, etc., and includes SLAM and auto‑recharging algorithms. Optional 4G modules enable remote monitoring and cloud command. As a source factory with complete R&D and manufacturing capabilities, we offer both standardized PCBA solutions for wholesale customers to quickly select and in‑depth customization – including motor parameter matching, sensor selection, navigation algorithms, wireless protocols, PCB dimensions, and interface definitions, all can be customized as required. Whether you are an OEM/ODM manufacturer, brand owner, or wholesaler/distributor, choosing our Patrol Robot Controller PCBA gives you factory‑direct cost‑effective products, stable lead times, and flexible customization services.
Product features
High‑Precision Dual‑Motor Differential Drive
●Supports dual‑channel BLDC or DC geared motors with FOC vector control for smooth start, closed‑loop speed control, and precise steering.
●Maximum drive current up to 30A (continuous) / 60A (peak) – suitable for grass, slopes, and other complex terrains.
●Built‑in electronic differential algorithm enables in‑place turns and curved cruising, with path tracking accuracy ≤5 cm.
01
Multi‑Sensor Fusion & Environmental Perception
●Integrated LiDAR or ultrasonic array interface for 360° obstacle detection and avoidance.
●Supports RTK‑GPS/BeiDou high‑precision positioning (cm‑level), combined with IMU (gyroscope + accelerometer) for inertial navigation and attitude stabilisation.
●Optional vision camera (for human/pet recognition), rain sensor, and light sensor for weather‑adaptive patrolling.
02
Intelligent Path Planning & Auto‑Recharging
●Built‑in SLAM algorithm (supports grid maps or topological maps) for yard map construction, path planning, and dynamic re‑planning.
●Supports auto‑recharging: automatically returns to the charging station when battery is low; docking accuracy ±5 mm; automatically resumes patrol after charging.
●Configurable electronic fences and restricted zones – patrol areas can be drawn via APP.
03
Multiple Safety Protections & Remote Control
●Integrated motor over‑current, over‑temperature, stall protection; interfaces for cliff sensors (infrared/ultrasonic).
●Supports emergency stop (physical stop switch or remote emergency stop); automatic power‑off on tip‑over.
●Optional 4G/Wi‑Fi modules enable real‑time video/map viewing via APP, remote drive, patrol schedule setting, and alarm push notifications (intrusion, abnormal movement, etc.).
04
Low‑Power Management & Power System
●Integrated lithium battery charge/discharge management (supports 7‑14 series cells) with balancing, over‑charge/over‑discharge protection; max charge current 10A.
●Built‑in DC‑DC multiple voltage outputs (5V/12V/19V) to power external devices (sensors, LiDAR, cameras, etc.).
●Standby power <0.5W; patrol operating power intelligently adjusted according to load to extend battery life.
05
Applicable scenarios
Home and villa courtyard security
As an important part of home intelligent security, it realizes 24-hour automated patrolling of courtyards, stranger intrusion detection and real-time alarms to protect the safety of private residences.
Park and factory perimeter patrols
Suitable for schools, industrial parks, logistics warehouses and other scenarios. Regular and fixed-point patrols of the perimeter can replace part of the manpower, improve security efficiency and reduce management costs.
Monitoring of high-end communities and public green spaces
Automated inspections in public areas such as communities and parks, with both safety monitoring and environmental monitoring (such as fire warning) functions, to build smart city nodes.
