A transformable robot comprises an arm structure, a leg structure and a head of the robot which are fixed to a ribcage structure. The arm structure includes a left arm and a right arm; the leg structure includes a left leg and a right leg; the ribcage structure includes a first steering gear fixed on an upper part of a second fixing frame; a rotating output shaft of the first steering gear successively passes through a top wall of the second fixing frame and a first backing plate to fixedly connected to a first steering wheel fixed on a first rotating frame; the first steering wheel is provided with an arc-shaped limited opening; a limited column on the first backing plate is movably passed through the limited opening; the rotating output shaft of the first steering gear rotates to drive the first rotating frame to rotate.

The present invention comprises two or more rotatable three-dimensional bodies and a linkage between the bodies. By means of the linkage, the rotation of a first body causes a second body to rotate. In at least one of the rotational positions of the two or more bodies, the shapes of the bodies are designed to create a shaped cavity between a first body and a second body. The shaped cavity may be a tunnel, or the shaped cavity may be a recess or niche. As the at least two bodies are rotated, the shaped cavity may appear or disappear or may change shape, position, or orientation as the bodies are rotated.

A toy vehicle track configuration includes a closed loop track extending from a first end to a second end, a booster, and a flexible diverter. The booster includes a booster wheel positioned to both: (i) propel a toy vehicle towards the second end as the toy vehicle moves from the first end towards the second end; and (ii) propel the toy vehicle towards the first end as the toy vehicle moves from the second end towards the first end. The flexible diverter is configured to guide the toy vehicle and an additional toy vehicle towards the booster in sequence as the toy vehicle and the additional toy vehicle move from the first end towards the second end. The flexible diverter is configured to pivot between gate positions and to move between a rest position and a compressed position.
