How can we 𝘢𝘭𝘵𝘦𝘳 😉 pretrained robot policies to coordinate without forgetting how to work alone?

On two XArm7 manipulators, ALTER achieves 90% coordination success while retaining 98% success (59/60 trials) on the original single-agent tasks.
The same adapted policy can coordinate with a partner and still work alone.

How can agents learn to coordinate without communicating when faced with multiple choices?

In our new work, MIMIC-D, we use decentralized diffusion models to achieve multi-modal, multi-agent coordination!

The results:
✅ Our decentralized policies utilize only local observations while still achieving implicit coordination. ✅ We demonstrate MIMIC-D’s capabilities across simulation benchmarks and real robot hardware.

Grabbing a set of keys, walking over ice – humans learn such tasks fairly easily. Prof. Ian Abraham wants robots to be just as adaptable. It’s a project that won him an NSF CAREER Award – congrats! https://t.co/FgcPTGowFP #YaleEngineering
