Abstract: An articulated toy vehicle is capable of straight and curved motion on a surface or through water. A front and rear assemblies are supported by wheels and are joined at a steering knuckle capable of positioning the assemblies in a vertical posture when the vehicle is moving along a straight path, and positioning the rear assembly in a non-vertical posture when the vehicle is moving along a curved path. A drive motor is mounted within and engaged with one of the wheels for driving the vehicle. A steering motor is mounted within the vehicle for setting the assemblies on a selected mutual angle to provide curved and straight line motion.
