the method comprising:

detecting a position of a surface where a human foot touches in a three-dimensional coordinate system having an origin of coordinate axes X, Y and Z as a position of the foot touch position detection art while the human is moving by foot; and

moving the foot touch position following apparatus together with the foot touch position detection part so as to follow the human that is moving by foot based on a detected result of the detecting by placing leis of the moving part at positions same as the position of the surface where the human foot touches in the three-dimensional coordinate system and three-dimensionally moving the foot touch position following apparatus.

10. The method as claimed in claim 9 , further comprising:

placing a leg part of the foot touch position following apparatus at the position where the human foot touched the surface detected by the detecting.

11. The method as claimed in claim 9 , further comprising:

determining a route, through which a wheel of the foot touch position following apparatus is to pass, based on positions where human feet touched the surface detected by the detecting,

wherein

the wheel is configured to move the foot touch position following apparatus by passing through the route.

12. The method as claimed in claim 11 , further comprising:

determining the route, through which the wheel is to pass, to be a route that passes through the positions where the human feet touched the surface detected by the detecting.

13. The method as claimed in claim 11 , further comprising:

determining the route, through which the wheel is to pass, to be a route that passes through a line that passes between the positions where the human feet touch the surface detected by the detecting.

14. The method as claimed in claim 9 , wherein

the foot touch position following apparatus is further configured to carry out a task while the foot touch position following apparatus is moving based on the detected result of the detecting.

15. The method as claimed in claim 9 , wherein

the foot touch position following apparatus is configured to carry out a task after the foot touch position following apparatus reaches a destination as a result of moving based on the detected result of the detecting.
