Robosen Flagship Grimlock

Robosen Flagship Grimlock is a fully automated transforming robotic interpretation of the G1 Dinobot leader.

The robot has two physical configurations:

Dino Mode
and
Robot Mode

The transformation between them is performed automatically through the coordinated movement of the robot's internal servo system.

This means users do not have to manually fold the legs, reposition the torso, or move individual body panels.

Instead, Grimlock executes the conversion as a programmed robotic sequence.

That makes the transformation itself part of the entertainment experience.

Grimlock has always been unusual within the TRANSFORMERS universe.

He is not simply another humanoid robot.

His alternate form is a dinosaur, while his robot form retains the physical characteristics of a heavily armored mechanical warrior.

Robosen's design attempts to preserve this identity while giving the character actual robotic movement.

The result is a machine that can transition between:

Dinosaur
↓
Automatic Transformation
↓
Robot
↓
Bipedal Movement
↓
Character Action
↓
Automatic Transformation
↓
Dinosaur

This dual-form architecture is the central idea behind the product.

Dino Mode is the feature that immediately distinguishes Grimlock from a conventional humanoid robot.

The dinosaur configuration measures approximately:

13.2 × 9.1 × 15.4 inches.

The form preserves Grimlock's recognizable Dinobot silhouette while incorporating the mechanical structures required for automated conversion.

Rather than being a static alternate shell, Dino Mode is a functional configuration of the robot.

The robot can be controlled while in this form through the Robosen app and supported voice commands.

In Robot Mode, Grimlock stands approximately:

15 inches tall

with dimensions of approximately:

8.6 × 13.7 × 15 inches.

The robot uses two legs for bipedal movement.

Its articulated body allows it to perform programmed poses and character actions while maintaining balance through its motion-control system.

This combination of a dinosaur alternate form and upright walking is one of the most technically interesting aspects of the product.

The defining mechanical feature of Flagship Grimlock is its automatic transformation.

Robosen describes the product as a dual-form, bipedal walking robot, with 34 high-precision intelligent servo motors coordinating the conversion and movement.

During transformation, multiple parts of the robot must move in a coordinated sequence.

The system has to control:

• Leg movement
• Body positioning
• Joint angles
• Balance
• Timing
• Final posture

The transformation therefore depends on both mechanical engineering and software-based motion control.

The result is a conversion sequence that happens without manually repositioning the robot.

The reverse transformation is equally important.

Once Grimlock is standing in Robot Mode, the control system can reposition the articulated body into its dinosaur configuration.

The process requires multiple joints to move in a specific order.

This is particularly important because the robot must transition between two dramatically different mechanical structures while maintaining controlled movement.

For a product built around a dinosaur character, this ability is fundamental to the experience.

Grimlock is designed to walk on two legs in Robot Mode.

Robosen describes it as a bipedal walking robot, with its 6-axis IMU continuously monitoring orientation and balance.

The IMU provides motion information that helps the control system manage the robot's posture.

Walking therefore requires coordinated control of:

• Legs
• Body
• Joint angles
• Balance
• Forward movement
• Turning

The result is a physical character capable of moving around rather than remaining fixed in a display pose.

Grimlock contains 34 high-precision intelligent servo motors.

These motors form the mechanical foundation of the robot.

They are responsible for coordinated movements associated with:

• Automatic transformation
• Bipedal walking
• Posing
• Character actions
• Arm movement
• Dinosaur configuration
• Programmed performances

The relatively high number of independently controlled actuators allows the robot to perform more expressive movements.

Robosen lists 85 microchips inside Flagship Grimlock.

The electronics support the robot's different hardware and software systems.

These include:

• Motor control
• Motion processing
• Transformation
• Sensor processing
• Voice interaction
• App control
• Programming
• Character actions

The important aspect is the integration between these systems.

Grimlock has to coordinate dozens of mechanical actuators while simultaneously processing movement and interaction commands.

Grimlock incorporates a 6-axis inertial measurement unit.

The IMU monitors the robot's motion and orientation.

For a bipedal robot, this is particularly important because balance changes continuously as the robot moves.

The motion-control system can use this information to help maintain:

• Stability
• Orientation
• Walking posture
• Controlled movement

This allows Grimlock to perform physical actions as a coordinated robotic system rather than a collection of independently moving joints.

Robosen's Grimlock is based on the visual language of the classic G1 character.

The design emphasizes the characteristics that define Grimlock:

• Dinobot appearance
• Mechanical dinosaur proportions
• Distinctive robot silhouette
• Metallic surfaces
• Character-specific accessories
• Crown
• Energon Sword
• Galaxial Rocket Launcher

The product is therefore recognizable in both its dinosaur and robot configurations.

The G1 connection is particularly important for this product.

Robosen lists Authentic G1 Appearance among Grimlock's major product features.

The company combines traditional character styling with modern robotic construction.

Materials listed for the product include:

• ABS
• PC
• PA66 + 33% glass fiber
• Aluminum alloy

and other materials.

This construction supports both the appearance and mechanical requirements of a transforming robot.

The crown is one of Grimlock's most recognizable accessories.

It reinforces the character's identity as the Dinobot leader and can be used as part of the robot's display and character presentation.

For collectors, this is more than a generic accessory.

It is part of the visual language that makes the robot immediately recognizable as Grimlock.

The Energon Sword is included with the robot.

The accessory can be incorporated into Grimlock's character actions and programmed performances.

It provides another way for the robot to reproduce the visual language of an animated character through physical movement.

The Galaxial Rocket Launcher is another included accessory.

Together with the sword and crown, it gives Grimlock a character-specific equipment set rather than relying on generic robotic accessories.

These details help connect the physical robot to the established identity of the G1 Dinobot.

One of the strongest character features is Grimlock's voice.

Robosen worked with Gregg Berger, the original G1 voice actor for Grimlock, to record more than 150 original TRANSFORMERS audio lines specifically for the robot.

This gives the product a direct connection to the original animated character.

The audio is not simply background music.

The voice lines can be combined with robotic movements and actions to create character performances.

Robosen lists 150+ original voice lines for Grimlock.

The voice library gives the robot a much stronger personality.

Instead of behaving like a generic machine, Grimlock can respond using character-specific dialogue and sound.

This creates a connection between:

Voice
Movement
Character
Action

The robot therefore communicates not only what it is doing, but also who it is supposed to be.

Grimlock recognizes 42 voice commands.

Voice control can be used to activate supported functions such as:

• Transformation
• Walking
• Character actions
• Other programmed behaviors

This allows users to interact with Grimlock without constantly reaching for a phone or controller.

The system is based on predefined commands rather than open-ended conversational AI.

In other words, the voice interface is designed primarily for robot control and character interaction.

One of the most natural uses of voice control is transformation.

Instead of manually operating the robot, users can issue a supported voice command and allow Grimlock to perform its conversion sequence.

The experience can therefore be reduced to a simple interaction:

Command → Transformation → Character Performance

This makes the robot feel more like an interactive character than a traditional transforming collectible.

Grimlock can also be controlled through the Robosen app.

The app supports control in both:

Dino Mode
and
Robot Mode.

Users can remotely control:

• Movement
• Transformation
• Actions
• Character performances

The connection uses Bluetooth Low Energy 5.0.

This provides more detailed control than voice commands alone.

Robosen provides four programming modes for Grimlock.

These include:

1. Block-Based Programming
2. Voice-Activated Programming
3. App Programming
4. PC Programming

The different interfaces allow users to create custom behavior at different levels of complexity.

A beginner can start with simple visual programming.

More advanced users can use PC-based tools to create more elaborate sequences.

Block-based programming provides a visual way to construct Grimlock's actions.

Instead of writing conventional code, users can assemble programming blocks to define sequences.

These can be used to control aspects such as:

• Movement
• Timing
• Actions
• Voice
• Character performances

This makes robotic programming more approachable for beginners.

Voice programming allows users to create actions using spoken commands.

It provides a more intuitive interface for people who want to experiment with custom robot behavior without starting with traditional programming concepts.

For a character-focused product, this is particularly useful because users can think in terms of:

“What should Grimlock do?”
rather than:
“How do I write the code?”

The Robosen app also provides programming functionality.

Users can create and manage custom actions directly from a mobile device.

This keeps programming integrated with the same platform used for remote control.

It makes the transition from simply operating Grimlock to creating new behavior relatively straightforward.

PC programming provides a more advanced environment for users who want greater control over custom actions.

Users can build more elaborate sequences by combining movement and other available elements.

This makes Grimlock useful not only as a collectible but also as an accessible platform for experimenting with robotic choreography.

Robosen provides a cloud-based sharing system for custom actions.

Users can:

• Create actions
• Share actions
• Discover community creations
• Download custom actions

according to Robosen's current product information.

This creates a community layer around the hardware.

The robot's capabilities are therefore not limited to the factory-installed performances.

Users can continue experimenting with new movements and sequences.

Grimlock also supports Robosen's MiniTheater feature.

The system provides two types of experiences:

SoloPlay

Grimlock performs independently as a character.

MultiPlay

Multiple compatible Robosen TRANSFORMERS robots can participate in coordinated simulations.

This turns the robots into physical performers.

Rather than simply displaying them together, users can create synchronized scenes involving movement, sound, and character actions.

MiniTheater illustrates an important aspect of Grimlock's design.

The robot is capable of combining:

Movement
Voice
Sound
Timing
Character actions

into a single performance.

This makes Grimlock closer to a robotic actor than a conventional remote-controlled figure.

Every Grimlock purchase includes a gold-painted collector's coin with a unique serial number, according to Robosen.

The coin adds a dedicated collector element to the product.

For owners who treat Grimlock as both a robot and a premium collectible, this provides a physical marker of the limited-edition nature of the product.

The engineering challenge of Grimlock comes from the need to make one physical machine operate in two very different configurations.

The robot must support:

Dinosaur Configuration

A four-legged mechanical silhouette.

Robot Configuration

A two-legged humanoid structure.

The same hardware has to accommodate both.

That requires careful coordination of:

• Joint ranges
• Servo torque
• Structural components
• Balance
• Transformation timing
• Software control

The 34-servo architecture provides the mechanical foundation for this system.

Bipedal walking introduces a fundamental robotics problem:

balance.

A stationary four-legged configuration naturally provides a broad support base.

A walking humanoid robot has a much smaller support area and must continuously manage its center of mass.

Grimlock's 6-axis IMU is used to monitor its motion and orientation as part of this process.

This is why the walking function is more technically meaningful than simply moving a pair of legs.

The robot has to coordinate its entire body.

Grimlock measures approximately:

Robot Mode

8.6 × 13.7 × 15 inches

Dino Mode

13.2 × 9.1 × 15.4 inches

Package

20.6 × 12.2 × 20.1 inches

The robot weighs approximately:

5.7 pounds.

The size makes Grimlock substantial enough to function as a display centerpiece while still remaining a portable consumer robotic product.

Grimlock uses a:

2500 mAh
11.1 V

battery.

Robosen lists an average charging time of approximately 90 minutes.

The actual operating experience can vary depending on how frequently the robot is walking, transforming, performing actions, and responding to interaction.

As with other motorized robots, intensive movement generally places greater demands on the battery than passive display use.

Grimlock communicates with the Robosen app through BLE 5.0.

This wireless connection allows users to control the robot from a mobile device.

The app functions as a central interface for:

• Remote control
• Transformation
• Actions
• Programming
• Community content

This gives Grimlock a software layer that can extend beyond its physical hardware.

The robot includes a Type-C peripheral interface.

Its power adapter is rated at up to 30W, with the product specifications listing a 15V/2A adapter configuration.

This provides the physical charging interface for the robot.

Robosen lists a combination of:

• ABS
• PC
• PA66 + 33% glass fiber
• Aluminum alloy

among the materials used in Grimlock.

The combination is designed to balance structural strength, weight, mechanical performance, and appearance.

This is particularly important for a transforming robot because its body must repeatedly withstand the mechanical forces associated with conversion and movement.

The dinosaur mode is not simply a cosmetic detail.

It changes the entire mechanical identity of the robot.

In Robot Mode, Grimlock is a bipedal character.

In Dino Mode, the same machine becomes a mechanical creature with a completely different silhouette.

That makes the transformation more meaningful than simply changing the position of a few decorative components.

The alternate form changes the way the robot occupies physical space and how the user interacts with it.

The appeal of Grimlock comes from the combination of three ideas:

Character

Grimlock is one of the defining Dinobots of the G1 era.

Transformation

The robot can automatically convert between dinosaur and robot configurations.

Robotics

It can walk, respond to voice commands, execute programmed actions, and interact through an app.

Together, these elements create something that sits between a collectible, a toy, and a consumer robot.

A traditional transforming figure is primarily concerned with mechanical conversion.

Robosen adds another dimension.

Once Grimlock transforms, it can continue to operate as a robot.

It can:

• Walk
• Pose
• Respond to commands
• Perform programmed actions
• Speak
• React through character sounds
• Participate in synchronized performances

The transformation is therefore the beginning of the experience rather than the end of it.

Grimlock represents a particularly clear example of character-centered robotics.

The machine's identity is built around a specific fictional character.

Its:

• Body
• Movement
• Voice
• Accessories
• Transformation
• Software
• Actions

are all designed around Grimlock.

This approach is different from building a generic robot and simply giving it the appearance of a dinosaur.

The robotic architecture is itself part of the character experience.

G1 TRANSFORMERS Fans

The combination of G1-inspired design and original voice recordings by Gregg Berger makes Grimlock especially relevant to longtime fans.

Dinobot Fans

The dinosaur transformation is the central physical feature of the product.

Collectors

The Collector's Edition designation, substantial construction, character-specific accessories, and numbered collector's coin make it suitable for premium collections.

Robotics Enthusiasts

The 34-servo architecture, 6-axis IMU, automatic conversion, and bipedal walking provide significant mechanical interest.

Makers and Programmers

Four programming modes and community action sharing allow owners to create their own robotic performances.

Interactive Entertainment Fans

Grimlock is designed to perform rather than simply sit on a shelf.

The best way to understand Flagship Grimlock is as a robotic collectible built around one of the most distinctive characters in the TRANSFORMERS universe.

It combines:

• G1 character design
• Automatic transformation
• Bipedal robotics
• Voice interaction
• Programmability
• Interactive entertainment

The result is a product that can function as a display piece when powered down and become a physical character when activated.

Grimlock is interesting from an engineering perspective because the product has to solve several problems simultaneously.

It needs to:

Transform

between two physical forms.

Walk

while maintaining balance.

Interact

through voice and app control.

Perform

through coordinated movement and audio.

Remain recognizable

as the G1 character throughout all of these functions.

The 34 servo motors and 6-axis IMU provide the physical foundation, while the software coordinates the individual systems.

The product can be experienced in several different ways.

As a Collector

Display Grimlock in either robot or dinosaur form.

As a TRANSFORMERS Character

Use voice commands to activate character dialogue and actions.

As a Robot

Control walking and transformation through the app.

As a Maker

Create custom movements and sequences.

As an Entertainer

Use programmed performances and MiniTheater features.

This flexibility is a major part of Grimlock's appeal.

The most interesting aspect of Robosen's Grimlock is that the company does not stop at reproducing his appearance.

The robot attempts to reproduce the physical behavior of the character.

A user can see the dinosaur.

Then command the transformation.

Then watch the machine stand upright.

Then make it walk.

Then trigger Grimlock's voice.

Then create a custom action.

The character has effectively moved from a fictional universe into physical space.
