Beyond Metal and Humanoid Forms: The Astonishing Future of Diverse Robots
Inspired by the insightful explorations of Veritasium, when we typically think about robots, images of metallic, humanoid figures, perhaps akin to those from Boston Dynamics, often come to mind. However, the robots poised to integrate into our daily lives in the future may look drastically different. Common sense suggests that for frequent human interaction, a soft, flexible design in various shapes and sizes might be preferable to something sharp, delicate, and heavy.
Instead of the science fiction archetype, advanced robots might prioritize safety and adaptability. Perhaps the gentle form of "Baymax" from Big Hero 6 offers a more accurate glimpse into our robotic future than the rigid "Sonny" from I, Robot.
This article, drawing inspiration from Veritasium's engaging approach to science, compiles insights into the surprisingly varied appearances of robots and the compelling reasons behind their unique designs.
A Word from the Innovator: Dr. Elliot Hawkes
We had the opportunity to reconnect with Dr. Elliot Hawkes, the brilliant scientist behind some of these fascinating robots, to get an update on their development. Regarding the remarkable jumping robots, he teased a new project:
"We have a whole nother project on jumping, and it doesn't even use springs. So I won't give away our secrets yet. But keep an eye out for that one too, 'cause that's gonna be
fun."
This hints at a revolutionary jumping robot design that promises to surpass their previous achievements.
Non-Humanoid Advantages: Specialization and Novel Abilities
The shift towards non-humanoid robots isn't just about safety. One of their most significant advantages lies in their ability to transcend the limitations of mimicking human actions. Instead, they are often specialized to master entirely new capabilities, tasks that no human can readily undertake.
The Unstoppable Vine Robot: Growth as Locomotion
Consider the "Unstoppable Vine Robot." This remarkable creation can extend to hundreds of times its initial size and remains unfazed by adhesives or sharp obstacles. Despite its seemingly simple construction, it holds significant potential for real-world applications, perhaps even in life-saving scenarios.
Powered by compressed air, these robots grow from their tip, allowing them to navigate tight spaces and traverse sticky surfaces with ease. Unlike wheeled robots that would become ensnared, the vine robot simply extends. Even punctures are often overcome by maintaining sufficient air pressure.
While the basic extending tube is not a complete robot, it forms the foundation upon which steering, cameras, sensors, and intelligence can be integrated.
The concept for this robot was inspired by the natural growth of a vine reaching for sunlight. The elegant solution involves an airtight tube folded upon itself, extending from the tip when inflated. Strategic taping allows for controlled bending, even creating deployable antennas.
Retraction is more complex, often requiring pulling on the "tail" of the material. Engineers have developed methods using internal rollers to prevent buckling during this process. The tube's diameter can also vary, allowing for inflatable sections that demonstrate the surprising power of low pressure exerted over a large area. This softness combined with strength makes these robots safe for interaction while capable of significant force.
Applications for vine robots are diverse, ranging from navigating collapsed buildings to medical intubation and even exploring other planets. Their ability to carry sensors into confined spaces makes them invaluable for search and rescue or archaeological exploration. Their burrowing capability in sand, achieved through fluidization with compressed air, opens doors for planetary surface studies.
The simplicity of the vine robot's design, inspired by nature, is striking. Basic versions can be quickly assembled, yet this fundamental concept has led to a wide array of specialized robots. Ongoing research includes projects focused on anchoring, inspired by the strength of plant roots, with potential applications in space exploration. Medical trials for intubation using miniature vine robots have also shown promising results.
The Highest Jumping Robot: Defying Gravity
A later visit showcased another incredible creation: a tiny robot that has achieved unprecedented feats in jumping. Weighing less than a tennis ball, this robot can leap to heights exceeding any other in the world.
In the competitive field of jumping robots, the previous record was 3.7 meters. This new design can reach an astonishing 31 meters. A true jump requires propulsion from the ground without any mass expulsion.
Inspired by the jumping prowess of animals like the galago, this robot utilizes a unique mechanism to achieve its remarkable height. While animals rely on a single powerful muscle contraction, this engineered jumper employs "work multiplication." It stores energy from multiple revolutions of a small motor over time, releasing it in a powerful burst. This is made possible by a latch mechanism that holds the spring under tension until the optimal moment.
The robot's lightweight construction (30 grams), the high energy storage capacity of its hybrid carbon fiber and rubber spring, and the principle of work multiplication are key to its performance. The spring design offers a nearly flat force profile, maximizing energy storage. Surprisingly, adding a small amount of weight to the top can also enhance jump height by optimizing energy transfer during launch.
While engineered jumping initially aimed to mimic biological systems, the introduction of work multiplication has provided a significant advantage. By decoupling the power output from the instantaneous capability of a single "muscle," robots can achieve feats beyond the natural world. Research continues to push the boundaries of jumping robot technology, with new spring-less designs on the horizon and potential applications in space exploration.
The Future is Diverse: Beyond Humanoid Forms
Inspired by the innovative spirit highlighted by Veritasium, the landscape of robotics is rapidly evolving. We are moving beyond the traditional image of metallic humanoids towards a future populated by robots of diverse forms, each uniquely engineered for specialized tasks. From the growing vine robot navigating complex environments to the record-breaking jumping robot defying gravity, science and engineering are constantly pushing the boundaries of what's possible. This exploration into these non-traditional robots reveals a future where ingenuity in form directly translates to remarkable and often unexpected capabilities.
