6 River Systems
6 River Systems, part of the Ocado Group and today sold as the Ocado Mobile Robot System under the Ocado Intelligent Automation umbrella, builds collaborative mobile robots that work alongside warehouse associates to streamline picking, putaway, and sorting. Their "Chuck" robots guide workers through optimized pick paths, reducing training time and increasing throughput. The platform supports batch and discrete picking workflows and integrates with leading warehouse management systems.
Our verdict
The Chuck collaborative-picking system retains a loyal user base, but ownership churn — Shopify to Ocado, then wind-down of the business — makes this a support-and-roadmap diligence exercise before anything else. Existing fleets deserve a maintenance strategy; new buyers should compare actively supported alternatives.
Strengths and risks
Strengths
- Well-liked associate-guided picking workflow
- Proven productivity gains in each-pick operations
- Simple deployment model for brownfield sites
Risks to manage
- Ownership and continuity turbulence — verify current support commitments before buying
- Roadmap investment uncertain relative to active competitors
- Fleet expansion and parts availability need contractual protection
