Abstract
A robotic surgical arm including a receiver configured to receive wireless communications from a robotic surgical instrument attached to the robotic surgical arm and a shield including a plurality of fingers each having a common shape and a connector being in contact with each of the fingers. When the connector is electrically connected to ground, the shape, dimensions and arrangement of the fingers causes attenuation of the transmission of electric fields through the shield.
