Soft robotic gripper shows valuable role in those tasks where robotic gripper met delicate objects. Comparison with rigid grippers, soft robotic gripper can grip/manipulate variety of target objects. This paper presents soft robotic actuators fabricated with three different low-cost silicones. These robotic actuators show fast actuation at low operating pressure. Three soft robotic grippers were assembled and tested through different tests to compare their performance. Different objects were chosen to test the grasping ability of gripper. Grippers shows the ability to grasp objects from 80.99 g to 4.07g at 30-13 kPa. Results shows that robotic gripper assembled with RTV 225 and RTV 4503 silicone shows the more reliable gripping as compared to Elastosil M4600 silicone. This work shows that these low cost and fast actuation of low-pressure grippers have great potential application in food industry, fruits industry and in daily life.
