A shock absorbing disruptor mounting system for a robotic arm includes a rack comprised of a linear guide structure and a carriage which is configured to travel on the linear guide structure. The carriage is selectively movable between a retracted position and an extended position and includes a plurality of wheels along its length. Each of the wheels has a wheel axis of rotation which is transverse to the direction of the linear guide structure centerline to facilitate rotation of the wheels on at least a portion of the linear guide structure responsive to the travel.
