## Steps
1. Find Goal
   - CNN to learn target (instructions) from Image
   - [Progress](https://gitlab.cba.mit.edu/amiraa/physical-computing-design-tools/-/blob/master/02_Presentation/CNN/CNN.md)
   - Create/get data to train
2. Auto Encoder to find latent representation for it
3. Control Strategy based on the
   - Train using the simulator + WANN
   - [Progress](../AI_that_grows/AI_grow.md)
4. Fit Arbitrary Graph/data flow on DICE
   - [Progress](https://gitlab.cba.mit.edu/amiraa/physical-computing-design-tools/-/blob/master/02_Presentation/prob/prob.md)
5. Assembly and Testing
   - [Meso-dice assembly](https://gitlab.cba.mit.edu/zfredin/meso-dice)
   - [Robotic assembly](https://gitlab.cba.mit.edu/amiraa/swarm-morphing/-/blob/master/Science_Robotics_Paper/LOI.md)

## 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
