How it works

A gearbox connected via crank plates to the kangaroo’s rear legs transforms motor rotation into walking/hopping. You can choose between two different gear ratios for the gearbox assembly.

When using the high-speed gear ratio, linkage rods should be attached to the lower holes of front legs and kangaroo hops upright while balancing on its tail. Changing the position of the tail allows the kangaroo to keep balance during high-speed running and enables it to change direction. Putting the tail straight will make the kangaroo go straight while setting it to the right/left will make the kangaroo turn to the right/left.

When using the low-speed gear ratio, linkage rods should be attached to the upper holes of front legs and the kangaroo walks on all fours. Attaching the rear legs to different holes in the crank plate gives you four different speed possibilities within slow speed mode.

The body is made from a transparent orange ABS resin that allows you to see all of the motors, gears, cranks, and linkage rods in action.
