Modeling and Generative-AI-Based Design of Load-Adaptive Gravity Balancing Mechanisms
Ryotaro Kayawake, Kazuki Abe, Shota Miyake +2
Load-adaptive gravity balancing mechanisms (LA-GBMs) can accommodate various loading conditions by passively changing their characteristics in response to payload variations. Howev…
Passive Luminescent Bellows Mechanism
Naoto Kikuta, Issei Onda, Kazuki Abe +2
The use of robots in disaster sites has rapidly expanded, with soft robots attracting particular interest due to their flexibility and adaptability. They can navigate through narro…
Reflexive Input-Output Causality Mechanisms
Ryotaro Kayawake, Haruto Miida, Shunsuke Sano +6
This paper explores the concept of reflexive actuation, examining how robots may leverage both internal and external stimuli to trigger changes in the motion, performance, or physi…
A Modular, Tendon Driven Variable Stiffness Manipulator with Internal Routing for Improved Stability and Increased Payload Capacity
Kyle L. Walker, Alix J. Partridge, Hsing-Yu Chen +5
Stability and reliable operation under a spectrum of environmental conditions is still an open challenge for soft and continuum style manipulators. The inability to carry sufficien…
Biological Organisms as End Effectors
Josephine Galipon, Shoya Shimizu, Kenjiro Tadakuma
In robotics, an end effector is a device at the end of a robotic arm that is designed to physically interact with objects in the environment or with the environment itself. Effecti…
Flexible and slim device switching air blowing and suction by a single airflow control
Seita Nojiri, Toshihiro Nishimura, Kenjiro Tadakuma +1
This study proposes a soft robotic device with a slim and flexible body that switches between air blowing and suction with a single airflow control. Suction is achieved by jet flow…
Soft robotic hand with finger-bending/friction-reduction switching mechanism through 1-degree-of-freedom flow control
Toshihiro Nishimura, Kensuke Shimizu, Seita Nojiri +4
This paper proposes a novel pneumatic soft robotic hand that incorporates a mechanism that can switch the airflow path using a single airflow control. The developed hand can contro…
Sound masking degrades perception of self-location during stepping: A case for sound-transparent spacesuits for Mars
Jose Berengueres, Maryam Al Kuwaiti, Ahmed Yasir +1
Most efforts to improve spacesuits have been directed towards adding haptic feedback. However, sound transparency can also improve situational awareness at a relatively low cost. T…
Inflated Bendable Eversion Cantilever Mechanism with Inner Skeleton for Increased Payload Holding
Tomoya Takahashi, Masahiro Watanabe, Kenjiro Tadakuma +3
Inflatable structures used in soft robotics applications exhibit unique characteristics. In particular, the tip-extension structure, which grows from the tip, can grow without fric…
Hundred Drones Land in a Minute
Daiki Fujikura, Kenjiro Tadakuma, Masahiro Watanabe +3
Currently, drone research and development has received significant attention worldwide. Particularly, delivery services employ drones as it is a viable method to improve delivery e…
Retraction Mechanism of Soft Torus Robot with a Hydrostatic Skeleton
Tomoya Takahashi, Masahiro Watanabe, Kenjiro Tadakuma +2
Soft robots have attracted much attention in recent years owing to their high adaptability. Long articulated soft robots enable diverse operations, and tip-extending robots that na…
Fire Resistance Deformable Soft Gripper Based on Wire Jamming Mechanism
Kenjiro Tadakuma, Toshiaki Fujimoto, Masahiro Watanabe +1
Able to grasp objects of any shape and size, universal grippers using variable stiffness phenomenon such as granular jamming have been developed for disaster robotics application.…
Internally-Balanced Magnetic Mechanisms Using Magnetic Spring for Producing Large Amplified Clamping Force
Tori Shimizu, Kenjiro Tadakuma, Masahiro Watanabe +3
To detach a permanent magnet with a controlled force much smaller than its original attractive force, the Internally-Balanced Magnetic Unit (IB Magnet) was invented and has been ap…
Radial-Layer Jamming Mechanism for String Configuration
Rio Mukaide, Kenjiro Tadakuma, Masahiro Watanabe +4
Grippers can be attached to objects in a rigid mode, and they are therefore used in various applications, for example granular jamming gripper. This paper introduces a cutting-edge…
Floating Displacement-Force Conversion Mechanism as a Robotic Mechanism
Kenjiro Tadakuma, Tori Shimizu, Sosuke Hayashi +4
To attach and detach permanent magnets with an operation force smaller than their attractive force, Internally-Balanced Magnetic Unit (IB Magnet) has been developed. The unit utili…
Smartphone-based Home Robotics
