# Digital Material Modeling and Simulation
Case study of the design and optimization of Macro-DICE.
Hardware Implementation:
- [VoxRob](https://gitlab.cba.mit.edu/bej/voxrob)
- [rover](https://gitlab.cba.mit.edu/ccameron/rover)
- [DM3](https://gitlab.cba.mit.edu/bej/dm3)
## Structure Simulation Integration
Using the [MetaVoxel simulation tool](https://gitlab.cba.mit.edu/amiraa/metavoxels):

## Optimization
- Two level optimization
- Shape (body) => [Hierarchal Local Online Shape Optimization](https://gitlab.cba.mit.edu/amiraa/metavoxels/-/blob/master/02_Presentation/top_opt/search.md)
- Control (mind) => [AI that grows](../AI_that_grows/AI_grow.md)
- Simultaneous optimization of shape and control
