Figure 7 is a shovel design that could potentially be used to help take a sediment sample. semicircle design allows the sample to easily stay in when the robot is moving. However, one possible weakness of the design may be that its untapered front design could give the robot trouble when it is trying to push the shovel into the sand. The shovel would be released using a servomotor, and dig into the sand as the robot moves forward. Once enough sand is collected, the servo will swing the shovel back into its normal position, thus containing and storing the sediment sample.
