ReSim is now SignalFlag
ReSim, the test infrastructure platform for physical AI, is now SignalFlag. Test across field data, hardware, replay and simulation. Why the name changed.

From sim to insight: How SignalFlag supercharges Isaac Sim for scalable, cost-efficient testing
NVIDIA's Isaac Sim, a robust robotics simulator, can be integrated with SignalFlag's evaluation platform to automate and scale testing. This collaboration offers robotics developers swift and economical insights into their advancements.

Building The SimOps pipeline for Physical AI
Running a single robotics simulation on your laptop is useful. Running millions of simulations in parallel in the cloud is a game changing unlock for physical AI. Here's a guide to the challenges (and solutions) of a building SimOps pipeline to enable this.

Perception case study: Analyzing object detection systems using SignalFlag
How do robots understand the world around them? The perception module is key — processing sensor data to detect and locate objects like cars and trucks in real time. Cameras and deep learning models play a central role in this stack, but evaluating these models at scale can be challenging. That’s where SignalFlag comes in — a simulation platform purpose-built for testing and analyzing robotic behavior.

An Infrastructure for Testing Embodied AI
Virtual experiences are the unit tests of Embodied AI. Here we explore the infrastructure and tooling required to unlock rapid insights, through testing with virtual experiences.

Testing Times Ahead for Embodied AI
Software 1.0 testing is insufficient for ensuring embodied AI is reliable and safe. The time is now for software 2.0 testing.
