Shape-Shifting Robots: Blurring The Lines Between Science Fiction And Reality

It’s tough to illustrate shape-shifting, what came to mind is the shapeshifting Terminator android T-1000 of Terminator 2. I decided to sketch a bionic woman cyborg, that has the robotics element, similar to T-800, character played by Arnold Schwarzenegger.

When it comes to the idea of shape-shifting, the concept is somewhat bounded by what we’ve seen, for example, on the big screen: The elusive yet charming Mystique in the highly successful Marvel series and DC’s Beast Boy – with his immaculate shape-shifting skills. It is hard to fathom how such an ability, or even the science behind it, can be mimicked and replicated by researchers in the real world, let alone achieve any feasible form of tangible success. That is, until today.

Researchers from Sun Yat-sen University, Zhejiang University, and Carnegie Mellon University have made a significant breakthrough in robotic technology, developing a deformable, magnetically controlled liquid metal for manufacturing robots. As can be seen in the demonstration video that was released, a humanoid robot made of liquid metal managed to escape a cage by simply melting inside the “jail cell”, exit, and then restoring its figure.

The shape-shifting sea cucumber

Unbeknownst to many, the impressive shape-shifting feat was inspired by an unassuming, humble source – the sea cucumber. An echinoderm often found on the ocean floor, the sea cucumber can reversibly alter the stiffness of its tissue to improve its load capacity. By replicating this unique ability in robots, researchers have taken a step closer to bringing the shapeshifting android Terminator assassin, the T-1000 is the main antagonist of Terminator 2: Judgment Day, to life, as well as offer promising applications in various fields such as biomedical technology and even space exploration.

To enable this shape-shifting ability, researchers embedded a magnetoactive phase transitional matter in liquid metal, allowing it to switch between solid and liquid states through heating with an alternating magnetic field and ambient cooling. This breakthrough concept, described in the journal Matter, yields a robot with high mechanical strength, load capacity, and rapid locomotion speed in its solid phase, as well as excellent shape adaptability in its liquid phase – including elongation, splitting, and merging.

Combining strength and flexibility

Traditional robots have limitations in manoeuvrability and flexibility due to their stiff and hard-bodied structures. Soft robots offer more flexibility but are weaker and harder to control. To address these shortcomings, the research team created a material that could shift between liquid and solid states. Gallium, a metal with a low melting point of about 86 degrees Fahrenheit, was used, and magnetic particles were embedded within it. Scientists can use magnets to control the robots, causing them to move, melt, or stretch.

The magnetic particles also make the robots respond to an alternating magnetic field, producing electricity inside the metal, raising its temperature. This induction heating causes the phase change, while ambient cooling solidifies the material again. The research team calls their invention a “magnetoactive solid-liquid phase transitional machine.”

In a series of tests, the new robot could jump up to 20 times its body length, climb walls, solder a circuit board, and escape from a mock prison. It could support an object about 30 times its weight in its solid state.

The robot was also used to remove a ball from a model human stomach in order to demonstrate its capability. The solid robot moved quickly to the ball, melted down, surrounded the ball, coalesced back into a solid, and travelled out of the model with the object. Gallium, as mentioned earlier, was used in this experiment, but a real human stomach has a temperature of about 100 degrees Fahrenheit, which is higher than the melting point of the metal. More metals, according to the authors, could be added to the material to raise its melting point.

  1. Origami-inspired robots

Researchers at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have developed a series of robots inspired by origami, the Japanese art of paper folding. These robots can fold into various shapes and perform a variety of tasks such as gripping, lifting, and moving objects. In fact, such a technology has the potential to be used in areas such as search and rescue operations, where robots must navigate tight spaces and adapt to changing environments.

  1. Soft robotics and artificial muscles

Soft robotics is another approach to create shape-shifting robots. Soft robots are made of flexible materials, making them more adaptable and better suited for tasks that require delicate handling. Researchers at Harvard’s Wyss Institute for Biologically Inspired Engineering have developed soft robots that can change shape and function using artificial muscles. These robots are capable of performing tasks like gripping, lifting, and even crawling, making them suitable for applications in healthcare, agriculture, and environmental monitoring.

  1. Modular robots

Modular robots consist of multiple interconnected units, allowing them to reconfigure themselves into different shapes and structures to perform various tasks. Researchers at the University of Pennsylvania’s GRASP Laboratory have developed a modular robot called SMORES-EP, which can autonomously change its shape and function. This type of robot can potentially be used in construction, disaster relief, and space exploration.
