How it works

Motor rotation is transferred to the legs via crank plates and linkage rods, causing the Mechanical Tiger to walk. The tiger’s stride depends on the crank holes to which the front legs are attached, which means there are four possible strides for you to choose from. Put this together with the two possible gear ratios and you get eight possible speeds. A reverse switch also allows backward movement. The body is made from a transparent yellow ABS resin that allows you to see all of the motors, gears, cranks, and linkage rods in action.
