Battery-powered motor

Motorized movement is a type of gimmick occasionally seen on Transformer toys, intended to make the toy seem more interactive and "alive" to its owner.

Since the electronic components for the battery pack and internal motors take up a lot of space within the toy and can be rather costly, this feature is usually seen on large toys with high pricepoints.

The relatively complex electronic features are vulnerable to breaking, and in addition the battery pack may require either large numbers of batteries or the rather "heavy" C-cells, which over time are particularly prone to leaking corrosive acid onto the toy's innards.

Additionally, this gimmick can limit a toy's articulation when it is located on a toy's robot mode joints, as the motors can restrict movement if the involved joints are moved without using the electronics. Due to this, motorized movement is often considered undesirable by collectors.

Toys with motorized movement

1985

Omega Supreme (reissued 2008)

Omega Supreme's tank mode drives itself across its trackways using rubber wheels; as it moves, the tank turret rotates 360 degrees while raising and lowering its cannon. In robot mode, Omega Supreme walks by very slowly inching its toes ahead.

1986

Sky Lynx (reissued 2008)

The Sky Lynx shuttle drives itself forward, while Sky Lynx's cat or combined beast modes walk quadrupedally.

Trypticon (reissued 2015)

Trypticon's dinosaur mode walks forward with a lumbering, front-heavy gait. In city and battle station modes, the motorized features make the radar dishes and cannon emplacements spin 360 degrees.

1990

Dai Atlas

The first Transformer toy with working rubber tank treads, Dai Atlas can roll forward in its robot, jet, and tank modes, and in the latter its drill nosecone will spin as well. In base mode, the tank treads form conveyor belts that can carry Micromasters around, and the central gun turret spins 360 degrees. Dai Atlas' motor also lends movement to the combined super-vehicle Big Powered.

1991

Grandus

Uniquely among Transformers, Grandus has motorized features but lacks the power source to activate them. When purchased as a stand-alone toy, users can manually raise and lower the elevator and rotate the radar dishes. These features can become motorized by linking Grandus to his in-story teammate Star Convoy (see below).

Star Convoy (reissued 2005)

Star Convoy features rubber treads that propel the toy forwards and backwards in truck or robot mode, as well as a radar dish that spins 360 degrees. When transformed into base mode, the motorized trailer can link up with Grandus, now powering the movement of its elevator and radar dishes.

2002

Armada Super Base Optimus Prime

The toy's primary gimmick is its auto-transforming trailer, which assumes one of three configurations when triggered by an infra-red signal transmitted from the cab robot. Transforming the cab into robot mode will cause the trailer to automatically flip open into a battle station. Transforming the cab into the torso portion sends the transformation command to the trailer, which raises itself up off the ground to become a pair of immobile, statuesque legs.
