Robots 🤖 make and break contact all the time. So what quantifies usefulness of contacts for a robot’s understanding of its environment? Check out our latest #RSS2025 paper on contact aware fisher information maximization!! 🧵below—-.

Think of the contact aware fisher information as a sensitivity measure that we can directly optimize wrt control-contact decisions to help robots learn about their environment more effectively!.

Taking a Taylor expansion over parameters yields the contact aware Fisher information matrix that quantifies how useful contact mechanics are to understanding physical constants!!.

We posed a contact aware max likelihood problem where the goal was to correlate robot control, sensing to physical (contact) constraints.

How much information is in contact interactions and how can we optimize for them to improve robot learning?. Check out our latest work on Behavior Synthesis via Contact-Aware Fisher Information Maximization led by myself and @ianabraha at #RSS2025!. Paper:

Doing some analysis, we find observation-only gradient information actually made policy updates more challenging. Removing this term led to interesting connections with student-teacher policy distillation and huge computational gains! check out @haoxiang_you 's post for more info.

We took a good hard look at the analytical policy gradient going from vision to state to dynamics to policy and realize it is separable!! -- one part only has state/dynamics info the remaining is observation-only.

The idea was quite simple, but cleaver --- we are very good/fast at trajectory opt with diff sims, why can't the same be true for visual policy learning?.
