Wireless Safety for AMRs at the Goods Transfer Station
An automotive plant operates around the clock and has several production lines that are supplied by autonomous mobile robots (AMRs). The transfer station serves as the central interface between the warehouse and the production line. Hundreds of transfers are handled here per shift.

Task Description
Autonomous Mobile Robots (AMRs) transport goods from the warehouse to the production line and hand them over to workers. Safety during interactions between humans (workers) and machines (AMRs) must be ensured at all times. Highly reliable and safe (safety) communication between humans and machines is therefore essential for smooth operation.
Implementation
The goal of the implementation is to ensure the safe handoff of production goods from the AMR to the workers. The AMR may only approach the platform after receiving explicit confirmation from the workers. Without confirmation, the AMR waits just outside the safety zone.
“Thanks to EchoRing, we have successfully implemented a wireless emergency stop system for our AGVs at a European car manufacturer, which has some of the strictest IT requirements in the automotive industry. The quick and smooth integration of the BRIDGE Es was supported by excellent assistance.”

Result
The goods transfer station now operates in full compliance with safety regulations while ensuring high throughput. The radio-based solution for the transfer and the position-dependent emergency stop ensures both a safe working environment and efficient transport within the warehouse. This is made possible by the use of the Bridge E with Black Channel communication for the CIP Safety protocol. The location-specific emergency stop function has significantly increased efficiency, as AMRs in the warehouse are not affected by downtime.
