Frequently Asked Questions

Sublayer vs Locus Robotics: which should you choose?

Locus Robotics and Sublayer serve entirely different domains: physical warehouse automation vs. Ruby AI software development. Choose Locus Robotics if you operate a high-volume warehouse needing 2-3x productivity gains via AMRs; choose Sublayer if you're a Ruby developer wanting a model-agnostic framework to build AI agents. They are not direct competitors.

Can I use Locus Robotics in a small warehouse with low order volumes?

Locus Robotics' RaaS model may not justify ROI for low-volume operations; it is best for high-volume fulfillment.

Does Sublayer support Python or JavaScript?

No, Sublayer is a Ruby framework. Non-Ruby developers should look at alternatives like LangChain.

What WMS systems does Locus Robotics integrate with?

It integrates with SAP EWM, Manhattan, Blue Yonder, Oracle, JDA, HighJump, Körber, Infor, Microsoft Dynamics 365, NetSuite WMS, and PSI Logistics.

Can Sublayer be used for production-scale multi-agent systems?

It is designed for experimentation and integration into Ruby apps; for large-scale orchestration, consider more mature platforms.

What is the pricing model for Locus Robotics?

Locus Robotics uses a Robots-as-a-Service (RaaS) subscription; contact them for a quote.

Does Sublayer offer a visual agent builder?

No, it is a code-based DSL for Ruby developers.

Which tools are best for automating warehouse picking?

Locus Robotics is purpose-built for warehouse picking automation with AMRs.

Is Sublayer free?

Yes, it is open-source and free. You only pay for LLM API usage if using cloud providers.
