  • Patent number: 8146695
    Abstract: A sled travels back and forth along a path established by a ground laid wire, the sled using a wire sensor to detect the presence of the wire in order to keep the sled on track. Steering of the sled is controlled by having a pair of motors, each operatively connected to a wheel on opposing sides of the sled, with the motors changing relative speed with one another for turn control. A ramp is located atop the sled to allow a garbage receptacle to be able to be rolled on and off the sled. Operation of sled travel is programmable or controlled by a remote control or a combination thereof.
