Marine robot is a valuable resource available to explore the treacherous uncertain waterbodies and enhance the understanding of the benthic. The robot’s operational environment is uncertain and dynamic that it necessitates an active emergency buoyant system to recover the robot from hazardous environment. A high nitrile rubber coated Nylon 6,6 bladder of 2 mm thickness is fabricated by means of hand layup method. To achieve this, the fabricated material is evaluated for its mechanical properties using ASTM D412 test methods and ISO 37:2011 standards. The test result indicates resounding success for the design by exhibiting a maximum tensile strength of 49.148 N/mm2 as per ASTM D412 and ISO 37:2011 test standard, an air permeability of 0 liter per hour (LPH) and was able to withstand pressures exceeding 68.67 bar without bursting. The tested material can serve as bladder for underwater operation, helping to protect the marine robot from severe damage in hazardous conditions.
