Title: Innovations of Mizuki Otagiri in Robotics Safety

Introduction

Mizuki Otagiri, a prominent inventor based in Kanagawa, Japan, has made significant contributions to the field of robotics through his inventive spirit. With a portfolio of 19 patents, his work focuses primarily on innovative safety devices and systems that enhance operational safety in automated environments.

Latest Patents

Among his latest inventions are the emergency stop pressure sensor, safety device, and safety system. The emergency stop pressure sensors are strategically installed on both side surfaces of a movable link of a robot arm used in assembly robots. This invention ensures that when a worker inadvertently enters the swing range of the robot arm, the pressure sensor detects this interaction and sends a signal to a control unit. Consequently, the control unit promptly shuts power transmission to the robot's driving source, effectively stopping the robot's movement.

The emergency stop pressure sensor is composed of a pair of electrodes and an intermediate layer made from rubber or a rubber composition. This intermediate layer is designed to generate power upon deformation, which is a result of contact with a worker. Depending on surface treatment methods applied to the intermediate layer, it exhibits different deformation characteristics under the same force, enhancing the safety response of the device.

Another notable invention includes an element featuring a pair of electrodes and an intermediate layer with deformability. This layer incorporates silicon compounds that possess unpaired electrons, providing essential functionality in various applications. These innovations demonstrate a compelling blend of safety and efficiency, crucial for the advancement of robotic technologies.
