A Gripper with Extreme Stiffness Anisotropy for High-Speed Handling of Fragile Foods

ICRA 2026poster

Handling fragile objects at high speeds presents a significant challenge. To address this challenge, researchers explored hybrid grippers and grippers with adjustable stiffness. However, grippers exhibiting anisotropic stiffness have received little attention. This paper presents an extreme case of …

Physically Consistent Preferential Bayesian Optimization for Food Arrangement

RA-L 2022

This letter considers the problem of estimating a preferred food arrangement for users from interactive pairwise comparisons using Computer Graphics (CG)-based dish images. As a foodservice industry requirement, we need to utilize domain rules for the geometry of the arrangement (e.g., the food layo

A Soft Robotic Hand Based on Bellows Actuators for Dishwashing Automation

RA-L 2021

Automation in the food services industry is not as developed as in the automotive and electrical industries. This may be because (1) the tasks involve high-speed operations in unstructured environments and (2) the lack of effective robotic end-effectors. In this letter, we focus on the automation of

Development of a Pneumatically Driven Flexible Finger with Feedback Control of a Polyurethane Bend Sensor

IROS 2018poster

A pneumatically-driven flexible finger equipped with a flexible sensor is realized for improving the performance of the soft robotic hand. First, we propose a flexible angle estimation sensor. This sensor measures the change in the amount of light passing through polyurethane material and estimates…

Mechanism and control of robotic arm using rotational counterweights

ICRA 2015poster

This paper proposes an actuation mechanism of robotic arms using rotational counterweights. The robotic arm is driven by gravitational and inertia forces of the counterweight mounted on links. The joints of the robotic arms are able to rotate freely though this robot does not have any actuators on j…
