Figure 4 - Brainstorming/Alternate Solutions - 3D Claw Design 1

Figure 4 would be an easy to operate claw design.  Although the design is simple, its straight inner edges would allow it to grasp onto almost anything with ease.  Like the other designs, Figure 4 would have its inner edges coated in rubber or a high friction material to prevent objects from falling out during transport.  The claw would hold onto the sample until it returns to the operator.  The claw would be operated using a geared down servomotor.
