A method of discriminating between different materials, the method comprising presenting a sample (4a, 4b, 4c) formed of a material to an electroadhesive gripper (1), and discriminating the material of the sample (4a, 4b ,4c) dependent upon whether the electroadhesive gripper (1) grips the sample. Typically, the method comprises driving the electroadhesive gripper (1) at a voltage, a frequency and duration and varying at least one parameter selected from the group comprising the voltage, the frequency and the duration with which the electroadhesive gripper (1) is driven, and then discriminating between the material of the samples (4a, 4b ,4c) dependent on whether it is gripped by the electroadhesive gripper (1) as each parameter is varied. |
