Title
(EN) PERSONAL PROTECTION DEVICE FOR ROBOT
(FR) DISPOSITIF DE PROTECTION INDIVIDUELLE POUR ROBOT
(JA) ロボットの対人保護装置
Abstract
(EN)
This personal protection device for a robot has a simple configuration comprising: a wearable device (3) attached to an upper garment (15) of a worker (2) who works around a robot (1), the wearable device (3) being configured to apply an alternating electric field in the vicinity of the body surface of the worker (2); a detection electrode (4) provided on the robot (1); and a measuring instrument (5) that measures the voltage of the detection electrode (4). When the robot (1) and the worker (2) come into close proximity and the voltage of the detection electrode (4) increases, a control signal corresponding to the voltage value measured by the measuring instrument (5) is sent to a controller (6) of the robot (1), and the robot (1) is caused to perform an operation for personal protection on the basis of the control signal received by the controller (6).
(FR)
Dispositif de protection personnelle pour un robot, lequel dispositif a une configuration simple, comprenant : un dispositif portable (3) fixé à un vêtement supérieur (15) d'un travailleur (2) qui travaille autour d'un robot (1), le dispositif portable (3) étant configuré pour appliquer un champ électrique alternatif au voisinage de la surface du corps du travailleur (2) ; une électrode de détection (4) disposée sur le robot (1) ; et un instrument de mesure (5) qui mesure la tension de l'électrode de détection (4). Quand le robot (1) et le travailleur (2) se retrouvent à proximité immédiate et que la tension de l'électrode de détection (4) augmente, un signal de commande correspondant à la valeur de tension mesurée par l'instrument de mesure (5) est envoyé à un dispositif de commande (6) du robot (1), et le robot (1) est amené à effectuer une opération de protection individuelle sur la base du signal de commande reçu par le dispositif de commande (6).
(JA)
ロボット(1)の周囲で作業する作業者(2)の上衣(15)に装着され、その作業者(2)の体表面近傍に交流電界を付与するウェアラブル装置(3)と、ロボット(1)に設けられる検知電極(4)と、検知電極(4)の電圧を計測する計測器(5)とからなる簡単な構成で、ロボット(1)と作業者(2)とが接近して検知電極(4)の電圧が高くなると、計測器(5)が計測した電圧値に応じた制御信号をロボット(1)の制御器(6)に送り、制御器(6)が受信した制御信号に基づいてロボット(1)に対人保護のための動作を行わせる。
