Proud to be part of this! SCAMPER builds on MIMIC-MJX with PULSE-like skill distillation (@zhengyiluo), improving latent motion control to enable naturalistic behavior for simulated neuroscience experiments.

1/14) Virtual animals are a long-standing goal in neuro-AI, but they should actually behave like real animals.

We present SCAMPER: a virtual rat for RL studies that moves naturally during both exploration, and goal-directed behavior.

How do you "see" with electric eyes? How does collective behavior emerge from individual interactions?
Nocturnal weakly electric fish evolved to do this, but studying naturalistic social behavior is very hard.

Our solution? Virtual 'fish' 🤖🐟⚡

The ultimate test of any physics simulator is its ability to deliver real-world results.

With MuJoCo Playground, we’ve combined the very best: MuJoCo’s rich and thriving ecosystem, massively parallel GPU-accelerated simulation, and real-world results across a diverse range of robot platforms: quadrupeds, humanoids, dexterous hands, and arms.

Best of all? You can get started today with a single command: pip install playground

With @Harvard, we built a ‘virtual rodent’ powered by AI to help us better understand how the brain controls movement. 🧠

With deep RL, it learned to operate a biomechanically accurate rat model - allowing us to compare real & virtual neural activity. → https://t.co/GaToq3AWTQ
