Erratic Kicker The erratic kicker was designed to mimic the thrashing lower body movements of a dying victim. We accomplished this by designing a body armature with custom linkages that provided 90 degree swivel movements in key locations. The addition of independent cylinders plumbed unevenly to created random movements even when triggered in a steady programming sequence. The armature also allowed for the customer to dress the body as they saw fit and had separate stiffening bars that connected at the hip and ankle areas to provide less violent movement when used un-suspended. The kicker performs extremely well inverted, lying, or in a standing position.
