AI Technical Summary
Existing sonar and laser scanning technologies have limitations in underwater object hardness identification, including high accuracy requirements, limited resolution, susceptibility to environmental interference, and poor performance in identifying small, close-range objects.
By utilizing the current signal generated by the dynamic change of the double electric layer at the solid-liquid interface, the hardness of underwater objects is analyzed through a current detection and acquisition circuit and a microcontroller. An electric gripper is used to grasp the object and apply pressure, and the hardness of the object is determined by the rate of change of the current signal.
It achieves low-power, simple underwater object hardness recognition, is suitable for small, close-range objects, and is unaffected by underwater environmental interference.
