A thought leader's perspective: Why Sensory Robotics' SR-1 outperforms traditional safeguarding solutions

Point cloud visualization from the Sensory SR-1 reveals a detailed 3D model of a factory environment, showcasing diverse structural elements through a spectrum of colors.

Sensory Robotics' SR-1 system fundamentally elevates current safety standards and significantly surpasses traditional methodologies in numerous critical areas, providing unparalleled safety, productivity, and adaptability.

1. Dynamic, Intelligent 3D Safeguarding

While traditional systems primarily rely on static, physical barriers or presence-sensing devices with fixed detection zones, the SR-1 system utilizes advanced 3D time-of-flight (ToF) sensors to create dynamic "virtual safety layers." Unlike hard guards and basic sensors, which offer rigid, binary protection, SR-1 intelligently interprets the environment in real-time. This allows the system to selectively adjust the robot’s speed or stop entirely, depending on the precise proximity and trajectory of detected humans.

Key Advantage:

• Flexibility & Responsiveness: Traditional fences or static sensors can’t adapt without manual reconfiguration. In contrast, the SR-1 can simply have the configuration changed in the GUI which adjusts its protection zones in response to changes in the environment.

2. Comprehensive, Real-Time Risk Mitigation

Traditional safeguarding methods rely heavily on stop-time analysis and spatial mapping to determine safe distances and reaction zones. While these practices are important, they are inherently static and reactive, often based on theoretical assumptions and periodic measurements. In contrast, SR-1 continuously maps its environment in real time using 3D data, effectively performing these analyses on a rolling basis. This eliminates the need for scheduled recalibration or manual updates and allows the system to adapt immediately to changes in the environment or workflow.

Key Advantage:

• Continuous Safety Analysis: SR-1 eliminates the need for manual periodic stop-time evaluations and pre-defined spatial mapping updates by automating and continuously updating these parameters, ensuring persistent compliance with ISO standards.

3. Increased Productivity through Intelligent Safeguarding

Traditional guarding (hard barriers, light curtains) interrupts productivity because they rely on full shutdowns when breaches occur. Sensory Robotics’ system uniquely differentiates between human presence and other objects or disturbances. For example, if a human operator briefly approaches a critical area, traditional safeguarding methods stop the robot entirely, leading to unnecessary downtime and productivity loss. The SR-1, conversely, reduces or temporarily pauses robot motion only in the precise area affected, maintaining productivity throughout the rest of the cell.

Case in Point (Automotive Installation):

• Sensory Robotics deployed SR-1 systems at an automotive manufacturer, successfully addressing human-robot-AMR collaboration challenges by selectively pausing robot motion, rather than performing complete stops. The result was significantly improved productivity and reduced nuisance stops, directly validating SR-1's superior ROI compared to traditional fencing or basic safety sensors.

4. Reduced Footprint and Enhanced Efficiency

Traditional safety barriers require substantial floor space, limiting operational efficiency and flexibility. The SR-1 system virtually eliminates this space constraint by utilizing unobtrusive ceiling or cell-mounted 3D sensors. The result is greater cell density, reduced facility footprint, and improved overall operational efficiency.

Reference:

• According to ISO/TS15066, collaborative robot applications (cobots) must ensure adaptive, real-time monitoring to achieve safe human-robot coexistence. SR-1 naturally extends these principles to larger industrial robots and robot cells, enabling flexible automation without sacrificing safety.

5. Simplified Installation and Maintenance

Integrators recognize the complexities involved in configuring physical barriers, placement calculations, and multiple safeguarding layers. SR-1 dramatically simplifies these processes through software-driven setup, minimizing the engineering effort associated with safeguarding design. Adjustments and recalibrations happen digitally, rapidly, and seamlessly, significantly reducing long-term maintenance costs and downtime.

Implementation Advantage:

• Installation time with SR-1 is substantially lower compared to traditional systems due to digital spatial definitions rather than physical installations, extensive wiring, and sensor alignments.

6. Scalability and Future-Proofing

Traditional safeguarding methods face limitations as automation needs evolve, requiring substantial retrofitting or costly expansions. SR-1’s software-based approach allows effortless scalability. As automation cells expand or reconfigure, the system can adapt with the click of a button, ensuring sustained compliance with evolving standards and changing industrial demands.

Future-Ready Insight:

• SR-1 inherently meets emerging safety criteria from ISO 13849 providing a robust foundation for future expansions, and significantly simplifying regulatory compliance as standards evolve.

Our customers acknowledge the importance of visibility in robot cells, emphasizing viewing considerations when using physical barriers. SR-1 offers comprehensive digital visualization through real-time 3D point cloud mapping, enabling operators, engineers, and maintenance teams to precisely understand the robot environment, improving diagnostics, troubleshooting, and safety verification.

Operational Advantage:

• Real-time visibility reduces the risk of safety bypass attempts (a problem noted in physical guarding methods) by providing clear and instant visual feedback on safety conditions and cell operations.

Conclusion: Elevating Safety Standards through SR-1

The traditional safety methods outlined, while historically effective, are increasingly inadequate for modern manufacturing demands that emphasize flexibility, productivity, and intelligent automation. Sensory Robotics' SR-1 system surpasses traditional safeguards across every dimension:

• Adaptability: Dynamic virtual safeguarding versus static physical barriers.

• Productivity: Intelligent safety stops versus total shutdowns.

• Compliance: Automated, continuous risk analysis versus periodic manual assessments.

• Scalability: Effortless digital expansion versus expensive physical retrofits.

• Efficiency: Minimal installation and footprint versus extensive hardware requirements.

Sensory Robotics, through the innovative SR-1 system, has redefined robot safeguarding, setting a new industry benchmark that traditional safety methods can no longer match. As manufacturing continues to evolve towards Industry 5.0, forward-thinking safety solutions like SR-1 are no longer merely beneficial, they're essential.
