The proposed gripper is specifically developed for grasping and manipulating objects that should be kept into restricted areas such as explosives, radioactive/ionized materials, and infected biological material specimens. The proposed gripper fingers can be retracted to pass through openings or slots and, once inside the restricted area, can be deployed in order to manipulate the objects without risk for the human operators.Analytical and numerical simulations are used to properly design and build a gripper prototype. Then, experimental tests are carried out to grasp objects of different sizes ranging from 5 to 10 mm. The obtained results are used to validate the gripper"s performance in terms of successful grasp and suitable accelerations and grasp forces.
