3Laws Robotics Office Hours

Join 3Laws for Office Hours every Wednesday at 8:30 a.m. Pacific.

To make it easy globally, that’s:

• 11:30 a.m. – New York / Toronto (ET)
• 4:30 p.m. – London
• 5:30 p.m. – Paris / Berlin

These sessions are tightly focused on how to run high-performance, safe autonomous systems with 3Laws. Join to ask questions about

• Configuring dynamic safety guardrails around AMRs and manipulators so they avoid rather than just slow or stop.
• Tuning zones, speed limits, and behaviors in mixed human–robot environments (forklifts, blind aisles, loading docks).
• Improving fleet operations and throughput without increasing incident risk.
• Integrating 3Laws with your existing stack (fleet managers, WMS/ERP/PLC, safety hardware).
• Measuring impact using concrete KPIs like utilization, MTBI, near-miss rate, and OEE.

Dynamic Safety Guardrails for NAV2/ROS Are Now Available

Supervisor ROS is available in a free community tier, but still requires a license key to be used. The license key can be obtained by requesting a key from the 3Laws Robotics page or by navigating from the 3Laws home page and clicking ‘Get Started’ in the upper right corner. Once approved, the license key will be sent to the email address provided in the request form.

Key Benefits of NAV2 / 3Laws Integration

Maximize Throughput and ROI with Dynamic Safety
Dynamic Safety modifies commands just enough at runtime to keep the robot moving at the highest safe speed. Compared with static or purely kinematic safety, this yields higher throughput and better asset utilization.

Robust in Multi-Agent, Complex Environments
The Supervisor enables automatic behaviors to route around blocked paths and obstacles, reducing gridlocks and deadlocks. It supports blind aisles, mixed-fleet interactions, and human co-existence by leveraging continuous sensing and continuous control.

Lower Autonomy Stack Complexity
By decoupling goal pursuit from obstacle avoidance, the Supervisor sharply reduces behavior tree complexity and brittle “if-this-then-that” logic. Teams can focus on product differentiation instead of special-case safety glue code.

Open-Source Core, Flexible Integration
You can build on NAV2’s production-grade, modular framework maintained by Open Navigation. Integration is straightforward: remap topics from the collision monitor, remove it, and insert the 3Laws Supervisor. This architecture lets you swap in components—such as the new Navigation Graph Routing and Tracking Server—without destabilizing the stack.

Enterprise-Grade Reliability with Provable Safety
The Supervisor enforces safety constraints in real time using Control Barrier Functions (CBFs), supporting compliance and risk reduction against standards like ISO 13849 and ISO 10218. The Supervisor ROS Community Edition is free for all R&D use; startups with ≤$500,000 in annual revenue can also use it free in production.

Using the New Route Server for Advanced Planning

This integration pairs with NAV2’s Navigation Graph Routing and Tracking Server, which enables lane-aware routing with application-specific rules. It supports progress tracking, place-based triggers, and use in mixed environments like agriculture or roadways.

You can use the Route Server as:

1. A drop-in global planner, or
2. The first stage in a three-step pipeline: fast high-level lane selection, followed by local goal planning over the next segment, and then dense local planning for a feasible trajectory. This is especially effective in large facilities.

Getting Started

A detailed tutorial is available on docs.nav2.org for integrating 3Laws Supervisor into your NAV2 stack.

• Download NAV2: Available under Apache 2.0 (for most components) at nav2.org.
• Download 3Laws Supervisor ROS CE: Access the free Community Edition at 3laws.io/supervisor.

The NAV2 and 3Laws integration is designed to make NAV2-based robots safer and more robust in real deployments—and to get more systems successfully out of the lab and into the field.
