Available models

Arm2DEnv

Simple 2D arm environment with 2 degrees of freedom and 6 muscles. The objective is to grab a ball randomly appearing in the space every 3 seconds.

# of muscles 6
# degrees of freedom 2
reward negative distance from the requested point

3D arm environment

Toy model

Note that Arm2DEnv model is simplified and not physiologically accurate. We suggest using it only for testing purposes.

L2RunEnv

NIPS 2017 challenge model, where you are asked to build a controller to make a musculoskeletal model run as quickly as possible. Read more in the documents on the NIPS 2017 challenge.

# of muscles 18
# degrees of freedom 9
reward distance travelled in a simulation step

HUMAN environment

ProstheticsEnv

NIPS 2018 challenge model, where you are asked to build a controller to make a musculoskeletal model with a prosthetic leg follow desired velocity vector changing in time. Read more in the documents on the NIPS 2018 challenge.

# of muscles 19
# degrees of freedom 14
reward negative distance from requested velocity
