Tamper-indicating device having robotic application features

A method of applying a tamper-indicating device to a drum enclosure using a robotic system, the drum enclosure including a drum body, a lid, a lid ring extending from a first flanged end to a second flanged end, the lid ring securing the lid to the drum body, a closure bolt having a head and a body extending through the first flanged end and the second flanged end, the method comprising:

• gripping a tab of the tamper-indicating device with a gripping assembly of the robotic system;
• positioning the tamper-indicating device such that it at least partially surrounds the closure bolt by moving the gripping assembly with the robotic system, the tamper-indicating device defining a cavity sized to receive at least a portion of the closure bolt and a bore, wherein the tamper-indicating device includes a mid-body portion, a first arm extending from the mid-body portion and partially surrounding the first flanged end, and second arm extending from the mid-body portion opposite the first arm and partially surrounding the second flanged end, wherein the mid-body portion includes a first side wall, a second side wall extending generally parallel to the first side wall, and an end wall extending between the first side wall and the second side wall, and wherein the tab extends from the mid-body portion of the tamper-indicating device;
• and
• inserting a pin with an actuator of the robotic system into the bore, the pin including a pin head and a pin body, the pin head extending into first side wall and the pin body extending across the cavity and into the second side wall such that the first side wall, the second side wall, the end wall, and the pin body collectively surround the body of the closure bolt.
