PROBLEM TO BE SOLVED: To provide an underwater robot which is hardly detected by an ultrasonic probe machine and which can perform underwater navigation and rotation in place.SOLUTION: An underwater robot comprises: a spherical housing 1; and four thrusters 10 attached to the housing 1, in which each thruster 10 is attached with 90°C interval in a circumferential direction of the spherical housing 1, and each thruster 10 has a direction conversion mechanism capable of converting by 360°, a thrust direction. Since the housing 1 is formed into a spherical shape, even if an ultrasonic is applied to the underwater robot, the ultrasonic is not reflected to a sound source direction, so that, the underwater robot is hardly captured by an ultrasonic probe machine. By combining direction conversion of the four thrusters 10, each operation of forward and backward movements, autorotation, revolution and underwater navigation, can be performed.SELECTED DRAWING: Figure 1

    【課題】超音波探信機による発見が困難であり、かつ潜航浮上やその場回転などが可能な水中ロボットを提供する。【解決手段】球形のハウジング1と、ハウジング1に取付けられた4基のスラスター10とからなり、各スラスター10は、球形ハウジング1の円周方向において90℃間隔に取付けられており、各スラスター10は、推力方向を360°変換できる方向変換機構を備えている。ハウジング1が球形であるので、超音波を当てられても音源方向には反射しないので超音波探信機による捕捉がなされ難い。4基のスラスター10の方向変換を組合わせることで、前後進と自転と公転と浮上潜航の各動作が可能である。【選択図】図1
