When to pick which
Choose the Covariant RFM-1 Pick Cell for high-mix e-commerce fulfillment or pharmacy dispensing where the primary challenge is item perception rather than transport. In an apparel warehouse handling thousands of unique SKUs, the RFM-1’s foundation-model intelligence allows it to pick items it has never seen before without manual training. While the 5kg payload is lower than the KUKA, its specialized inference API and 6-axis precision make it superior for stationary kitting or returns processing where SKU variability is the main bottleneck. It is the optimal choice for high-throughput sorting centers requiring advanced computer vision.
Select the KUKA KMR iiwa for dynamic manufacturing environments like automotive assembly or electronics line replenishment where mobility is essential. Unlike the stationary Covariant cell, the KMR iiwa combines a 14kg payload cobot arm with an AMR base, allowing it to navigate between workstations and transport components across the factory floor. With 7 degrees of freedom and an 8-hour runtime, it excels in inter-cell logistics and lab automation where the robot must interact with humans safely and perform tasks at multiple locations. Its Java-based Sunrise.OS provides the deterministic control needed for complex assembly sequences.
