RoMA: Interactive Fabrication with Augmented Reality and a Robotic 3D Printer 
Why this is used?
It provides an interactive fabrication system for modeling any of the materials through its Argument Reality headset combined with the robotic hand.

Software required:  RoMA AR CAD editor
 

Key features : 
  --> design and fabrication occurs simultaneously
  --> single volume is enough for this simultaneous fabrication
  --> time efficient
 
How does it work?
The user wears the AR headset and the user have a controller on his hand, using controller user draws the required shape of the model by seeing it in VR headset, and after completion of half of the user's design, the robotic hand starts implementing it, in the meantime, the user can draw the further part of his design, and it even supports the modification of the drawn design before implementing by the robotic hand.
 
Hardware used
1) AR headset by connecting an OVR Vision stereoscopic camera to an Oculus Rift VR  headset
2) Oculus Touch controllers to serve as the input tools for RoMA
3) Adept S850 6DOF robotic arm
4) standard E3D hot-end 


Conclusion: RoMA helps in quick and efficient 3D printing of new design or addition of created design to already physically existing model/product by its VR support.
