Advanced Sealing Systems to Shield Robots in Extreme Environments

Quick Summary

• Collaborative robots (cobots) are increasingly deployed in outdoor environments, facing challenges like extreme weather, chemical exposure, dust, and mechanical stress.
• Seals play a critical role in ensuring robotic reliability by preventing environmental ingress, mechanical wear, corrosion, and chemical degradation. Innovative sealing designs address these challenges effectively.
• Freudenberg Sealing Technologies developed IPSR (Ingress Protection Seals for robots), featuring a Z-shaped geometry designed for durability and minimal friction in robotic joints.
• Materials like Fluoroprene XP and EPDM provide excellent chemical resistance, UV protection, thermal stability, and flexibility under varying temperature conditions. Specialized coatings reduce friction to enhance precision and energy efficiency.
• Advanced simulations using Finite Element Analysis (FEA) optimized seal geometries before prototyping to predict real-world performance under extreme conditions such as high mechanical stress or temperature cycling.
• Validation tests confirmed the seals meet IP65 standards for protection against contaminants while enhancing safety in human-cobot interactions through reduced friction delays during emergency responses.

Indian Opinion Analysis
Sealing technologies play a critical role in advancing robotics used across industries such as agriculture or wind power maintenance where operational environments are harsh but reliability is non-negotiable. The innovations presented by Freudenberg-such as IPSR seals tailored to cobots-are noteworthy because they enhance both the lifespan of robots and their precision while lowering maintenance disruptions significantly. For India’s growing industrial automation markets spanning agriculture to manufacturing sectors reliant on SCARA or Delta robotics configurations highlighted here-solutions addressing resilience concerns could directly support enterprising productivity goals aligning national needs with imported technology innovations.
