In the past few years, we have covered plenty of interesting robot grippers here. The KIT Gripper is also worth a look. It is a multifunctional gripper for disassembly tasks. It has 5 degrees of freedom for manipulation, a jaw gripper with 1DOF rotation joint and a 1DOF closing joint. It has a tool mounted camera for screw detection and force/pressure sensors.
As the above video shows, this robot can be taught to automatically disassemble a hard disk.
