In this study, we propose a reconfigurable laminate mechanism based bistable tail for Throwbot transforming into a ball type and a wheel type. Various robots such as snake robots, drones, and throwing robots for life-saving missions on behalf of humans at disaster sites have been studied. In particu
Soft pneumatic actuators (SPAs) that can perform three-dimensional movements are being developed to perform more diverse tasks beyond simple bending. The conventional PneuNet actuators have expansion limit layers, which can obtain more tip force by limiting the expansion of the bottom. However, the
With the introduction of the Fourth Industrial Revolution and the spread of smart factories, the demand for small-quantity batch production systems is rapidly increasing. As a result, the implementation of robotic gripper systems that can handle various objects is required. Until now, grippers have…
In this study, a throwing robot equipped with an shock absorbing structure, utilizing paired-Cross Flexural Hinge (p-CFH) and an airbag, was fabricated and validated to assess the effectiveness of its impact absorption mechanism. This robot was developed in anticipation of situations where direct hu…
In recent years, the role of robots across industries has become increasingly diverse, and they are now required to perform complex missions beyond simple repetitive tasks. However, robots used in confined spaces that humans cannot reach or in disaster field missions have challenges in performing va…
In this paper, we have developed a protection module for Light Detection and Ranging (LiDAR) sensors used in outdoor unmanned vehicles. Bio-inspired wiping motion was figured to have more efficient and excellent wiping performance than conventional cleaning methods for LiDAR sensors. An water wiping…
In our daily life, when a small amount of sweat or water forms on a person's hand, we can empirically feel that the friction force of the hand increases, and the objects are gripped well. However, if sweat or water forms heavily, we can feel the friction decrease when holding an object. In this stud…
This study proposes a modular Multi-axis Elastic Actuator (MAEA) for legged robots that can effectively cope with impacts that may occur during dynamic maneuvering. MAEA has multi-axis compliance and can measure the torque without additional encoders. Therefore, effective impact resistance is possib…
This letter proposes and verifies a new method, the ring-pull mechanism, to overcome the disadvantages of existing wearable robotic gloves. By attaching a ring to the metacarpopha-langeal joint of the finger, the ring-pull mechanism supplements the grasping force of the user, while reducing the weig
By modeling the system with the mechanical, electrical, and magnetic field, we can derive the system equation for the actuator modeling. As it is not easy to conclude the output signal from the equations, we used Simulink to simulate and check the performance aspect of the system. After that, we did…
Recently, diverse research has actively been conducted to control the posture of jumping robots using an inertial tail mechanism. However, the inertial tail mechanism has a high probability of collision with obstacles. In this study, a momentum wheel mechanism is proposed to achieve the same attitud…
