Note that this is not a CG image of Marvel's new movie, but a real robot created by Disney.


It as like as two peas in the movie. The robot's height is 76 cm, 1:1 restore the "Galactic guard" in the setting of little gerut.

Disney's research on it is not just a show off. Maybe you will see this cute little grut soon. Because the original intention of developing it is to design a robot that can interact with tourists for Disneyland.


Moreover, with a little modification to the exterior, the robot can be transformed into Master Yoda in star wars or the seven dwarfs in snow white.

In 2018, they built a prototype of little grut's leg.


In 2019, little grut learned to walk under the guidance of researchers and attracted employees to stop and watch in Disney's office, although he occasionally fell.


By 2020, Disney will be putting on little grut's coat and facial expression. The little grut robot can not only stand on one foot, but also wave and dance.


At this point, little grut was basically finished.

The wire behind the little grute is used to receive the field programming instructions during debugging, which is unnecessary. Battery life is up to 45 minutes.

At that time, what tourists will see in the park is a vivid image of independent action and interaction with people.

Bring in Boston power employees

When you see this, do you think of atlas, a Boston powered robot that danced a few months ago.


That's right. The team that developed little grunt included former Boston power engineers.

In 2016, Disney recruited Scott La Valley, who developed the first prototype version of the biped atlas for Boston power. La valley was mainly responsible for atlas's leg system at that time.


After joining Disney, La valley began to develop a self balancing automatic biped robot.

Because of so many special high requirements, Disney can only develop its own robot technology from scratch.

The technology behind it

The first thing to solve is the skeleton of the robot.


The 3D printing metal skeleton is hollow, allowing air to flow inside to cool the heating parts.

In fact, today's little grunt is a heat sink: air is inhaled at the collar, pushed through the whole body by fans and exhaust pipes embedded in the framework, and finally flows out at the bottom of the trousers.

Little grut's legs use the reverse dynamic balance system, which makes the movement more efficient and faster. And even if you push it gently or put a hand on its shoulder, it can easily stay still.


To minimize the size of the robot, Disney has developed a clever gear system that allows different joints to share motors.

Next comes a special set of motors that dynamically change torque and torque and have additional sensing capabilities to improve stability and respond to uneven ground and environment.

Finally, the robot is powered by built-in batteries and can run for 45 minutes on a single charge. Disney is already developing a lighter 3D printing skeleton, which may last longer in the future.

From fantasy Engineering

Little gerut's Kiwi project is from Walt Disney imaging (WDI).


The word "imaging" comes from the combination of "Imagine" and "Engineering", which is responsible for the design and construction of Disneyland around the world.

Four years ago, Disney announced at the south by Southwest (Sxsw) music festival that it would launch cartoon robots in the park.

Disneyland values the reality and integrity of these fantasy characters. For example, tourists are not allowed to see two Mickeys at the same time, because there is only one Mickey in the world.


Disney has also stipulated that actors who play these roles in costumes should not disclose what roles they play in social media or interviews.

In addition to making these characters look more real, there is another reason for creating autonomous robot actors, which is that adult humans can't play those small characters.

As for the reason why we started from little grut, it is less difficult to interact. After all, it has only one line.



However, Disney robot actors don't need to master the difficult rolling and other movements like atlas.

Besides the smooth movement of the foundation, we need the ability to interact with tourists, especially children.

For this reason, Disney cooperated with Hanson robotics, the world's leading company in robot expression,


The Nami shaman in Avatar

Sophia, the first robot to be granted human citizenship, came from this company.


Disney has made many other efforts to bring fantasy characters to the real world through robots.

For example, this stunt robot can play spider man and roll in the air.



In addition, Disney also launched the bb-8 robot toys in Star Wars. Although they have been discontinued, they are still available now.


Fantasy Engineering Department said that it will take some time for little grute to appear in the park, and the part of interaction with human needs to be further improved to deal with emergencies.

For example, when a child suddenly rushes to hug little grute, how can the robot keep on falling to the ground without causing harm to the child.
