In this research, we developed a "sledding type walking machine" that can prevent flail mainly in snowy areas by using a force sensor and an optical three-dimensional motion analysis device. Using the further developed walking machine, It was evaluated mechanically by an analyzer. Using the measurement data of the motion analysis device, the position of the center of gravity on the Z axis, the floor reaction force, and the moment applied to the knee obtained by applying Plug-in gait were measured. The position of the center of gravity was lower than that of normal walking, and it was confirmed that the floor reaction force decreased and each moment and reaction force decreased. Furthermore, the results with the wheel type walker were almost the same, and the validity of the sled type walker could be confirmed.
