Doctoral Dissertation

Orochi is a wearable robot that is designed for daily tasks. Orochi's versatility is enabled by its two different end-effectors and flexible body that resembles a snake-formfactor.

Designing Serpentine-Shaped Robotic Appendages for Augmenting Daily Interactions

Augmenting humans with robotic appendages have long been envisioned in sci-fi and pop-media. However, we are yet to see anyone using such wearables in our daily lives. Therefore, this doctoral dissertation uses a user-centric approach to explore and validate the usability of such systems within our daily lives, with emphasis on the versatile snake formfactor. The outcomes of this dissertation establishes an understanding and provides design considerations that cover requirements, expectations and deployability domains of these novel wearable systems.
