1000W Dual Drive Controller for Robot

The CAN bus dual-drive controller is a drive system specifically designed for mobile robot chassis, such as AGVs, inspection robots, transport robots, or agricultural robots. Its core functionality lies in synchronously controlling the independent motors of the left and right wheels via an industrial-grade CAN bus protocol, enabling precise differential steering and motion coordination. Typically integrated within the chassis system, this controller operates in conjunction with motors, gearboxes, and sensors. It supports RS485/CAN communication interfaces and PID regulation to accommodate complex terrains and operational demands.

Widely employed in robotic chassis, with a focus on demanding operational environments,

such as the uneven terrain encountered by outdoor AGVs, industrial settings with intense electromagnetic interference, or scenarios requiring high-precision navigation (e.g., warehouse logistics, inspection operations). Particularly suited for robotic chassis applications involving sudden load changes, requiring 24-hour continuous operation, and demanding stringent positioning accuracy (synchronisation error <0.1%).

These dual drive controllers for robot are typically integrated into the core of a robot's functional framework, facilitating independent management of both drives. This is crucial for achieving differential steering, a mechanism where variations in motor speed enable turning and precise path tracing without conventional steering hardware.

Independent Control: It allows users to separately control the rotational speed, direction, and torque of each motor. For instance, on a robotic chassis, a dual-drive controller enables two wheels to rotate at differing speeds, thereby facilitating steering.

Synchronous Control: Dual-drive controllers can also synchronise both motors to maintain consistent speed and torque. This is vital for applications requiring smooth operation, such as transport robotic chassis.

Differential Control: Steering is achieved by regulating the speed differential between the two motors, which is critical in robots demanding precise directional control.

Compatibility: Dual-drive controllers typically accommodate various motor types, including brushless DC motors (BLDC), brushed DC motors, or servo motors, ensuring broad applicability.

Integrated Protection Features: To safeguard equipment, dual-drive controllers commonly incorporate multiple protective functions such as overcurrent protection, overvoltage protection, undervoltage protection, and overheat protection.

Automated Guided Vehicles (AGVs) and Logistics Robots

Application Scenarios: Employed in e-commerce warehouses, manufacturing plants, or logistics centres for goods dispatch handling, cargo transportation, and inventory management.

Suitable For: Dual-wheel differential drive enables efficient 90-degree or 180-degree on-the-spot turning, adapting to narrow shelving aisles. When integrated with magnetic strips, QR codes, or SLAM navigation, it achieves precise point-to-point transport.

Tour Guide and Retail Service Robots

Application Scenarios: Tour guide robots in shopping centres, museums, or hotels, providing information, customer direction, or sales support.

Suitable For: In crowded public spaces, dual-wheel differential drive enables flexible on-the-spot rotation and slow movement to avoid collisions. Combined with voice interaction and screen displays, it reliably executes centralised routes, enhancing user experience.

Agricultural Robot Chassis

Suitable for precision farming applications within greenhouse facilities (e.g., seedling tray transport), orchard/tea plantation inspections (e.g., pest and disease monitoring), and field data collection (e.g., soil moisture detection). These applications leverage their strengths in coordinate and path planning to achieve centimetre-level precision during forming or semi-forming processes.
