Figure 5 - Brainstorming/Alternate Solutions - 3D Claw Design 2

 Although Figure 5 is a promising design, its pointed design would only allow it to grab large samples.  Another concern with the design of Figure 5 is that it would not be able to grab the plant sample efficiently.  To help it hold onto the sample better, the inside edges would be coated in rubber or another high friction material.  The claw would hold onto the sample until it returns to the operator.  The claw would be operated using a geared down servomotor.
