One takeaway from #
IROS2026# : the core of embodied RSI (recursive self-improvement), is what a robot can already do shapes what it can learn next.
Think of how data collection changes as a policy gets better. Once a trained policy can handle most of a task on its own, human operators move past full demonstrations and step in only where it fails, correcting those moments. The data shifts from broad imitation to targeted, high-value snippets that would be far more expensive to source from scratch.
Simulation can provide the initial skills that get this process moving.
The important design choice is deciding which physical details matter for the skill being learned. A simplified environment can be useful when it preserves the relevant constraints and interactions. Real-world testing then reveals where those assumptions stop holding.
That suggests a practical development cycle:
Train an initial capability in simulation.
• Use it to support more informative data collection.
• Study failures to find missing experience or wrong assumptions.
• Update the setup and test again.
At Axis Robotics, this connects closely to how we think about scaling robot data. Alongside dataset size, we should ask what new situations the data covers and which weaknesses it helps resolve.
A useful simulation pipeline should make the next experiment more informative. A useful dataset should make the next policy more capable.
The opportunity is to build those two processes together, so each improvement helps create the conditions for the next one.
