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 …

Optimization of Preemptive Impact Mitigation without Prior Collision Testing

ICRA 2026poster

Effective impact mitigation strategies are cru- cial for preventing potential damage to both robotic sys- tems and their operational environments during high-velocity and dynamic maneuvers, as well as during the execution of high-precision tasks. The successful implementation of impact mitigation st…

State Estimation and Environment Recognition for Articulated Structures Via Proximity Sensors Distributed Over the Whole Body

ICRA 2026poster

For robots with low rigidity, determining the robot's state based solely on kinematics is challenging. This is particularly crucial for a robot whose entire body is in contact with the environment, as accurate state estimation is essential for environmental interaction. We propose a method for simul…

Integrated Grasping Controller Leveraging Optical Proximity Sensors for Simultaneous Contact, Impact Reduction, and Force Control

RA-L 2024

Grasping an unknown object is difficult for robot hands. When the characteristics of the object are unknown, knowing how to plan the speed at and width to which the fingers are narrowed is difficult. In this letter, we propose a method to realize the three functions of simultaneous finger contact, i

External Sensor-Less in-Hand Object Position Manipulation for an Under-Actuated Hand Using Data-Driven-Based Methods to Compensate for the Nonlinearity of Self-Locking Mechanism

IROS 2023poster

Dexterous manipulation using an under-actuated hand has been a challenging task due to its non-linear dynamical characteristics. For a linkage-based under-actuated hand designed to be used to grasp and manipulate large, heavy, and rigid objects stably, precision grasping is necessary, which makes th…
