A shock absorbing disruptor mounting system for a robotic arm (102) includes a rack (112) comprised of a linear guide structure and a carriage (114) which is configured to travel on the linear guide structure. The carriage (114) is selectively movable between a retracted position and an extended position and includes a plurality of wheels (314,614) along its length. Each of the wheels (314,614) has a wheel (314, 614) axis of rotation which is transverse to the direction of the linear guide structure centerline (308,608) to facilitate rotation of the wheels (314,614) on at least a portion of the linear guide structure responsive to the travel.
