This is the Mechanical Tiger Tamiya71109

Power from the rotating motor is transferred to the legs via crank plates to make the tiger walk. Two possible gear ratios coupled with four different strides let you choose eight different speeds. A reverse switch also allows backward movement. Coil spring tail wags when the model walks. The tiger's body parts have been molded with yellow semi-transparent plastic, giving the tiger a futuristic look. Assembly is very simple with use of screws and snap-lock parts. Soft foam "boots" are used on the legs to keep from damaging floors as this robot tiger walks. Run on flat, smooth surfaces. Avoid running over slopes, on bumpy roads or on thick carpet. The length is 155mm and the weight is 3.7oz. This is another robot that I would like to build because our school is the Auburn Tigers and I think that it would be a nice project to do for me and it represents our school.
