Project Description

Control Oriented Muscle Model for an octopus arm. The package extend the implementation of Cosserat Rod simulation done by PyElastica.

Install

The package can be installed using standard python package installer (pip):

pip install coomm

or from source code:

cd <repository directory>
git clone https://github.com/hanson-hschang/COOMM
pip install -e COOMM

Examples

Note, all the example cases written uses the original version of COOMM (v.0.0.1), with older version of PyElastica (v.0.2.2). If you are interested in reproducing the result from the paper, please match the version.
