The OMRON robot is equipped with:

Use Case 1: Pick and place operation in collaboration with non-OMRON robots
The LD250 takes a defined route between stations where it transports goods. These goods are picked and placed by other robots that are not part of the OMRON eco system. Therefore, the ARCL interface of the LD250 is used to get the location data every 100ms. If the LD250 approaches a pick & place station, he informs the cobot at that station to get in position for a faster pick & place operation. When the LD250 arrives at the station, the cobot picks/places the good. After the picking/placing operation is done, the LD250 gets a message that the operation is finished and moves on to the next station.
The communication is done over 5G by sending messages via a MQTT broker. The cobots and the LD250 subscribe to topics to which they react with appropriate operations.
The 5G connection is realized via a Quectel 5G module that is interfaced to the Ethernet port of the LD250. The necessary software for running the module as well as the retrieving of the location data is done by a Raspberry Pi 5. The power for running all devices on the LD250 is supported by DC-DC converters that are directly connected to the Battery of the LD250.
Additionally, the LD250 continuously sends a low-latency 4-camera HD live stream over the 5G connection to a server. For the moment the camera streams are only stored for later analysis of incidents, for example, after an accident. But in the future it would be an idea to use this camera data for environmental awareness.
Use Case 2: Network coverage measurements at the SAL 5G Testbed using the LD250
The LD250 was used to automate measurements of 5G performance parameters in the LIT factory. Every 100ms the position/rotation of the LD250 as well as the 5G performance parameters like RSRP (Received Signal Power), MCS (Modulation Coding Scheme), etc. have been collected and sent to the server for processing and visualization.
Alexander Croce (OMRON) about the cooperation with SAL:
“We are excited to work together with SAL on the future of 5G communication and its possibilities. Now after the first tests in the SAL 5G testbed, we are absolutely convinced that we want to address further use cases. It is important to us to test practice-orientated applications from industry under scientific conditions. And SAL is the right partner for this. Many thanks to Stefan Wimmer and the SAL team for the integration of Omron Robotics.”
