Abstract: A robot especially adapted for use in hazardous environments, and particularly adapted for explosives disposal, includes a wheeled platform carrying a winder mechanism which ensures that the remote control cable will not be fouled by the robot or its attachments. Coaxial with the winder mechanism is a turret mechanism that can rotate indefinitely and which carries thereon a manipulator arm section which, includes a first arm pivotable through about 110.degree. and which carries thereon a second arm which is pivotable through about 120.degree. and carries a bulkhead to which any of a plurality of end effectors can be connected by way of a quick connect and disconnect mechanism. The end effectors include a set of links having different lengths, one or two extension links, a wrist and gripper mechanism, an aiming and disruptor mechanism, and a relocatable surveillance camera.
