1. POSITION-CORRECTING TOOLS FOR 2D DIGITAL FABRICATION

2. Digital Fabrication

3. Motivation The current digital fabrication is too expensive for
personal use, we aim to reduce the cost of digital fabrication.
Leverage human’s mechanical range

4. Challenge Localization -- Determining the current position of the tool
Actuation
-- Correcting the tool’s position

5. Localization(1/3) Based on computer vision
-- A tool with camera can tracks the material
over which it moves
Zitova and Flusser [2003] and Szeliski[2006]

6. Localization(2/3)

7. Localization(3/3)
We leverage specially-printed tape marked with high-contrast patterns
to make it possible to track materials that have no visual features
of their own (such as sheet metal or plastic) and to increase
robustness under varying lighting conditions.
