Robot Controller Speed Thresholds for Strut Strength Reduction

The patent applies local quality by setting different speed threshold values for different coordinate axes based on the actual operational requirements. The robot body moves along a traveling rail supported by struts, and high-speed motion is only required along the rail direction (one axis), not in perpendicular directions. By setting appropriate threshold values for each axis, the system ensures safety where needed while avoiding unnecessary over-engineering of the struts for directions where high speed is not required, thus reducing manufacturing costs.

The patent changes the parameter of speed threshold values from a uniform single value to axis-specific differentiated values. This allows the system to adapt the safety parameters to the actual operational characteristics of the robot, where high-speed motion is confined to specific directions along the traveling rail. This parameter differentiation resolves the contradiction by maintaining safety for critical high-speed directions while reducing structural requirements for non-critical directions.

The patent applies dynamics by implementing dynamic speed threshold monitoring and control that adapts to the actual operational context. Rather than statically limiting the robot's dynamic capability, the system dynamically monitors the speed of the robot hand portion along different coordinate axes and only restricts motion when threshold values are exceeded. This allows the robot to operate at maximum speed along the traveling rail direction while preventing dangerous high-speed motion in perpendicular directions, thus maintaining productivity without compromising safety.

The patent segments the speed control into different coordinate axes, allowing independent threshold setting and monitoring for each axis. This segmentation enables the robot to achieve high speed along the traveling rail (productivity requirement) while maintaining lower speed thresholds in perpendicular directions (safety requirement). The segmented approach resolves the contradiction by allowing high performance in critical directions while reducing structural requirements in non-critical directions.

The patent changes the safety monitoring parameter from general abnormal operation detection to specific speed threshold monitoring along different coordinate axes. By setting appropriate threshold values for each axis based on actual operational requirements, the system avoids unnecessary halts during normal high-speed operation along the traveling rail while still detecting and responding to dangerous conditions in perpendicular directions. This selective parameter-based monitoring reduces false alarms and unnecessary stoppages, maintaining productivity while ensuring safety.

The patent applies local quality by implementing safety monitoring and halting control specifically for critical directions (perpendicular to the traveling rail) rather than uniformly across all directions. The robot is allowed to operate at high speed along the traveling rail where productivity is critical, while speed thresholds are set to detect and halt abnormal motion in perpendicular directions where safety concerns are paramount. This localized safety approach resolves the contradiction by minimizing unnecessary interruptions to productive operation while maintaining safety where needed.
