Battery-powered motor

Battery-powered motors are 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.

Toys with battery-powered motors

The Transformers

• Omega Supreme (1985)

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. The Encore line in 2008 included both a reissue of Omega Supreme and a redeco of that figure into Guardian Robot.

• Sky Lynx (1986)

The Sky Lynx shuttle drives itself forward, while Sky Lynx's cat or combined beast modes walk quadrupedally. This toy also received a fully-functional Encore rerelease in 2008.

• Trypticon (1986)

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. This toy was retooled into Gigastorm in 1998's Beast Wars II toyline, and eventually the original Trypticon design would be reissued in the Platinum Edition series in 2015.

• Rumbler (1991)

The ones that aren't in your parents' attic.

• Slicer (1991)

European-exclusive Action Masters Rumbler and Slicer each included battery-powered motorized exo-suits. Action Master figures could ride these exo-suits either in a four-wheeled vehicular or two-wheeled upright configuration. The front wheels of the exo-suits had attachments for melee weapons (spiked flails for Rumbler, spreading blades for Slicer) that would spin as the wheels turned. The two exo-suits were the same base design, differing only in plastic colors and weapon accessories.

Fight! Super Robot Lifeform Transformers

• Dai Atlas (1990)

The first Transformer toy with working rubber tank treads, Zone 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.

• Grandus (1991)

Uniquely among Transformers, Return of Convoy 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 (1991)

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. This toy was reissued in 2005.

Armada

• Super Base Optimus Prime (2002)

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 signals the trailer to raise itself up off the ground and become a pair of immobile, statuesque legs. There were at least 7 different versions of this toy released over the years, all retaining the motorized features.

Transformers (2007)

• Ultimate Bumblebee (2007)

In robot mode, Ultimate Bumblebee has motorized features that turn its head, raise its arms, and flap its door-wings. This toy was slightly retooled for the Revenge of the Fallen toyline in 2009.

Robosen Collector's Edition

• Optimus Prime Auto-Converting Robot (2021)

Robosen Optimus Prime represents a blurring of the line between toys and high-end showroom electronics. 27 servo motors powered by rechargable lithium-ion batteries allow the programmable robot to drive itself in truck mode, transform, and walk and assume a wide variety of poses in robot mode. Users are encouraged to develop and share new movement programs for Optimus Prime, downloading them through the included USB. The toy is vulnerable to damage if commanded to move or transform on surfaces that are too rough (i.e. concrete) or that don't provide uniform traction (i.e. thick carpets).

• Optimus Prime Auto-Converting Trailer and Roller (2022)

This version of Optimus Prime's trailer is a companion piece to the Robosen Optimus Prime, above. It measures 3 feet long in trailer mode, with internal and external lighting, and upon voice command or app control it uses 60 microchips and 18 motors to move some of its 2,000 individual parts, self-transform and rise into its interactive battle station / repair tower mode, move its various doors and ramps, and deploy a remote-controlled Roller.

• Grimlock Auto-Converting Robot (2023)

Robosen Grimlock is another very "extra" motorized display piece like the Optimus Prime above. Its 85 microchips and 37 servo motors allow it to fully move about and transform in response to voice commands or the app interface.

• Megatron Auto-Converting Robot (2024)

At 21" tall, Megatron is the largest of the Robosen interactive programmable Transformers, and turns into a tank mode with working treads. Features include 112 different LED functions, 36 servo motors, 118 microchips, and over 200 lines of dialogue.

• Bumblebee G1 Flagship (2025)

"G1 Flagship" Bumblebee stands 15" tall in robot mode and transforms on command into a licensed VW Beetle. The figure responds to user input with 37 servo motors, 67 microchips, and over 200 lines of dialogue.
