Steering-by-Wire (SBW) technology is an advanced robot chassis steering technology that uses algorithms to eliminate the mechanical connection between the control handle and the moving mechanism, achieving steering control through electrical signals. This technology makes control safer, more flexible, and more precise, while also providing a technical foundation for advanced autonomous driving or autonomous mobility.

On robotic chassis, the application of SBW technology enables more flexible steering and movement, enhancing the robot's maneuverability and adaptability. Additionally, eliminating mechanical connections reduces the weight and cost of the robotic chassis, thereby improving its overall performance.

Operational Advantages

The operational advantages of wire-controlled steering technology in robots are mainly reflected in the following aspects:

Wireless steering technology, in simple terms, refers to controlling steering through electrical signals rather than traditional mechanical connections. On the robot chassis, the advantages of this technology are primarily reflected in the following aspects:

Enhanced Flexibility: SBW enables the robot chassis to perform more flexible steering maneuvers, adapting to various complex scenarios.

Weight Reduction: By eliminating mechanical connections, the overall weight of the robot chassis is reduced, which significantly aids in improving the robot's mobility and efficiency.

Safety Redundancy: Dual controller + multi-power backup design automatically switches in case of failure, ensuring the safety of emergency braking or evasive maneuvers.

Intelligent Collaboration: Seamless integration with navigation systems (such as lidar, SLAM) enables autonomous path planning and real-time adjustments, improving automation efficiency.

Cost Reduction: The maintenance cost of the steer-by-wire system is relatively low, as it reduces wear and replacement needs for mechanical components.

Scene Adaptability: Suitable for industrial AGVs, robot chassis, special-purpose robot chassis, and other scenarios, supporting stable steering in extreme environments such as high/low temperatures, underwater, and steep slopes.

On a robot chassis equipped with line control steering technology, the setting of safety boundaries is critical. The following are some principles for setting safety boundaries:

Redundant Design‌: To ensure the reliability of the steering system, a redundant design is adopted. That is, when the main steering system fails, the backup system can immediately take over and continue to perform the steering task.

Fault Detection and Handling‌: The steer-by-wire system is equipped with fault detection and handling mechanisms that monitor the system's operational status in real time and take appropriate measures when faults occur.

Speed and Travel Limits‌: Based on the specific application scenarios and performance characteristics of the robotic chassis, reasonable speed and travel limit parameters are set to prevent safety incidents caused by loss of steering control.

Personnel Training and Monitoring‌: Personnel operating the robot chassis should undergo professional training and assessment to ensure they are familiar with the robot's operating procedures and safety standards. Additionally, personnel should monitor the robot chassis in real time during operation to ensure safety.
