Kuchibashi: 3D-Printed Tweezers Bioinspired by the New Caledonian Crow's Beak

TL;DR

This paper introduces Kuchibashi, a 3D-printed, crow-beak-inspired tweezer, demonstrating its superior ability to handle large spherical objects and positive user perceptions of safety.

Contribution

The study presents a novel bioinspired tweezer design and evaluates its usability, showing advantages over traditional tools in specific object manipulation tasks.

Findings

Kuchibashi outperforms hands and conventional tweezers in handling large spherical objects.

Participants perceived Kuchibashi as safe and secure.

The prototype was successfully implemented and evaluated through user studies.

Abstract

In this study we implemented Kuchibashi, the New Caledonian Crow beak-like tweezers, and conducted a user study to evaluate the prototype's usability. We proved that Kuchibashi is superior in interacting with large spherical objects than hands and tweezers. Also, impressions of security and safeness were perceived positively by the participants.
