1. A robot system for spraying chemical for exterminating termite, in a place under a floor of a structure, said robot system comprising:

  • a moving truck including an endless track mechanism which is able to horizontally turn, a pair of rollers operatively connected to said endless track mechanism and driven by a DC geared motor, and a main body having a tank containing the chemical and a radio circuit for outputting and inputting an electrical signal thorough radio communication;

    a lift mechanism operatively connected to said main body to lift said main body relative to said endless track mechanism, said lift mechanism including means for changing a distance between said moving truck main body and endless track mechanism;

    a detecting mechanism including an encoder operatively connected to said rollers and arranged to detect a travel distance and a rotational angle of said moving truck;

    an automatic control mechanism including an onboard computer mounted on said moving truck main body, a host computer separate from said onboard computer, and a radio modem through which said onboard computer being electrically connected to said host computer, and arranged to automatically control operations of said moving truck;

    a CCD camera mounted on said truck main body to confirm the location of the objective wood section in wood structural members under the floor;

    a monitoring mechanism for displaying an image of said objective wood section;

    corner section detecting means for searching an approach or contact of said moving truck main body to the structural members to find a corner section of the structural member;

    means for detecting a distance between said moving truck main body and said objective wood section, and including an infrared sensor; and

    an automatic operation mechanism including means for memorizing a location and shape of the wood structural members after confirmation of all the wood structural members to which chemical is to be sprayed, and means for accomplishing a next time spray of chemical in accordance with a memorized data derived from a preceding time spray.
