A remotely controlled vehicle for traversing various terrains to accomplish missions in a hostile environment. This remotely controlled vehicle has a main chassis with rotatable tracks on either side thereof that supports a central body of the vehicle. Auxiliary chassis in a forward and rearward direction also carry tracks on either side, with these auxiliary chassis being pivotable to raised or lowered positions to accomplish movement over uneven terrain. The body carriers a deployable arm including a shoulder, an elbow and a wrist, with this arm being provided with five degrees of motion. The drive means throughout the vehicle for the main tracks and for the essential components of the arm are carried out through the use of motor driven planetary gear assemblies to achieve the necessary torque and speed. The body in one embodiment carries a cable drum and provision is made to rotate the drum, to allow it to be free reeling or to lock the same, in order to control the desired feed to or from the drum of a cable carrying signals to and from the vehicle. All of the motions are controlled remotely from a control station. Except for the shoulder and elbow joints, all wiring of the components is internal, and the position of various elements is determined using potentiometers and the like resistive elements.
