Major Components:
As is specified in the Pollen Onshape drawings, the chest is intended to provide support for the electronics and also for the orbita and head. However, it was determined that an FDM-printed chest isn't able to provide such support.
Because of this, the torso evolved to use a set of 80/20 rails to provide strength and structure to the torso, as well as a frame to hold the electronics.
Some of the electronic mounting pieces were modified to fit with the 80/20 rails/brackets.
While the Pollen Reachy uses metal poles for supporting the torso within a setup, we instead added a baseplate to provide overall support.
