I like to simulate how humans and animals move. Creator of SCONE (https://scone.software) and Hyfydy (https://hyfydy.com).
It’s the forward dynamics simulation that runs at 20x real-time

This model has 35 degrees-of-freedom, 120 musculotendon actuators and full contact geometry. Simulations run at around 20X real-time. No motion data was used.

The scapula is kept in place through spring forces between points on the scapula and an ellipsoid on the thorax. Springs that push the points outwards have a higher stiffness than springs that pull the points towards the ellipsoid.

The muscle activations are optimized for the hand to reach the red sphere targets; the scapular motion emerges independently.

This uses a 30-dof model with 122 compliant musculotendon units, simulated using Hyfydy and trained using depRL. No motion data was used for training.
