This manuscript describes a pressure sensor equipment for underwater robot external attachment. It is difficult to add sensors to many underwater robots. Most pressure sensors have a diaphragm plate, and the pressure sensor must be exposed to the environment to deform the diaphragm plate. Therefore, to add a pressure sensor to an underwater robot, it is generally necessary to redesign both the outer shell and the robot’s inner structure. To solve this problem, we propose encapsulating a pressure sensor in a plastic film bag. Vacuum packaging technology is applied to fabricate the sensor equipment. This technique is called the robot packaging method, and it is possible to fabricate the sensor equipment rapidly and inexpensively. This manuscript shows experimental results that it is necessary to encapsulate a sufficient amount of insulating fluid in the plastic film bag to fabricate the pressure sensor equipment by the robot packaging method. |
