Embodiments of a patient trans- port device comprise a rigid structural member; a patient support member coupled to the rigid structural member, a propulsion assembly coupled to the rigid structural member, wherein the rigid structural member comprises a motor operable to oscillate between frontward rotation and backward rotation, first and second continuous tracks responsive to the motor and rotatably coupled to the rigid structural member, and a power source configured to energize the motor and exchange electrical energy with the motor, and at least one controller communicatively coupled with the power source and programmed to execute machine readable instructions to oscillate the motor between frontward rotation and backward rotation, the oscillation of the motor being operable to cause the first continuous track and the second continuous track to stop. |
