An impact absorption type robot feet apparatus is provided to distribute impact by permitting only one end of a first slidable foot-board and a second slidable foot-board to contact ground and other ends of the first and second slidable foot-boards to be connected to an elastic member to absorb impact applied to the foot-boards. An impact absorption type robot feet apparatus(10) includes a shaft(60), and a first slidable foot-board(40) and a second slidable foot-board(50). The shaft is fastened to a lower end of a robot leg(20a). The first slidable foot-board is jointed to a lower portion of the robot leg such that the first slidable foot-board is slidable in a lengthwise direction about the shaft so as to distribute impact applied from ground. The first slidable foot-board has one end having a front contact surface(41) contacting ground and the other end connected to a rear surface of the robot leg through an elastic member(49). The second slidable foot-board has one end with a rear contact surface(51) contacting ground and the other end connected to a front surface of the robot leg through an elastic member(59). The first slidable foot-board and the second slidable foot-board have centers which are cross-linked with each other such that the first slidable foot-board and the second slidable foot-board independently slide and elastically move in accordance with the load of a robot and impact applied from ground.
