6 Principles for Designing New Age Robots
Understanding Moravec's Paradox in Robotics and Defining 6 Principles to Avoid The Trap
Today I would like to talk about a delightful conundrum that has long baffled the brightest minds in robotics – Moravec's Paradox. Imagine a world where your robot can casually discuss quantum mechanics at the level of Einstein like its no big deal but fall on their faces when asked to put on a sock or a glove. Yes, we've engineered AI that can beat grandmasters in chess but ask it to pass the salt, and suddenly, it's in existential crisis mode.
You see, we've inadvertently stumbled upon an ironic twist: our creations are wizardly mathematicians but clumsy apprentices in the art of the mundane. It's like building a supercomputer that can predict weather patterns but can’t make heads or tails of an umbrella.
This paradox is not just a whimsical oddity; it's a window into the complexity of human intelligence and the often-overlooked genius of our everyday abilities. This is the very conundrum that Hans Moravec was trying to address when he formulated the paradox. When it comes to machines, the tasks that are cognitively challenging are easier to achieve than the simpler mundane tasks of day to day life. A tool like ChatGPT may be creative enough to draft the architectural plan for the next Burj Khalifa, but try creating a robot that could build a sand castle as good as a child.
In this article, I have addressed this paradox and designed 6 principles to apply when building new age robotics to avoid getting trapped if not completely escape this paradox.
Understanding Moravec's Paradox
Let's break it down, shall we? Picture this: a robot can calculate the complex mathematics required to navigate a spacecraft through an asteroid belt. Impressive, right? But ask it to make sense of a child's crayon scribbles, and it's as baffled as a penguin at a desert party.
What Exactly is This Paradox?
In the 1980s, when hairstyles were questionable and computers were the size of small elephants, Hans Moravec, along with his contemporaries, observed something peculiar. They noted that high-level reasoning requires relatively little computational effort compared to low-level sensorimotor skills. In human terms, it's easier for a robot to play chess than to walk without bumping into furniture.
This paradox sprang from the early days of AI, a time when optimism was high, and computers were low (in processing power, that is). Researchers thought that replicating human intelligence was a hop, skip, and a jump away. They soon realised, however, that the hop was more like quantum physics, and the skip resembled neurosurgery.
The Relevance Today
Fast forward to today, and this paradox still taunts us. Our AI can diagnose diseases and trade stocks, yet struggles to grasp the subtleties of a handshake or the art of brewing a decent cup of tea. It turns out, the things we humans do without a second thought – recognising faces, interpreting body language, catching a ball – are incredibly complex to encode into algorithms.
So, why is this paradox more than just an amusing party fact for tech geeks? Because it highlights a fundamental truth about AI and robotics: understanding and replicating human sensory and motor skills is a Herculean task that we’re still trying to master.
Atlas from Boston Dynamics
Now, let's turn our gaze to a real-world marvel, a robotic celebrity - Atlas from Boston Dynamics. This humanoid robot, more agile than some of us on a Monday morning, gives us a front-row seat to the spectacle of Moravec's Paradox.
First things first, Atlas is no ordinary robot. This bipedal bundle of wires and metal can do backflips, navigate complex terrain, and even perform impressive gymnastic routines. If robots had Olympics, Atlas would be eyeing the gold medal in acrobatics.
While Atlas might be the Michael Jordan of robots in a gymnastics hall, put it on a running track, and you’ll see a different story. Despite its acrobatic flair, Atlas can't match even a modest human running pace.
This shortcoming isn't just about speed; it's about the nuanced, adaptive motor skills humans use effortlessly every day. Running for humans involves a complex mix of balance, agility, and split-second adjustments – something we mastered as toddlers but remains a tall order for our friend Atlas.

A Six-Step Framework to Navigate Moravec's Paradox
So while companies like Boston Dynamics and Tesla are making great strides in building advanced robotics, the curse of Moravec’s paradox still haunts the process. It impedes us in achieving our goals of combining hi-tech robotics with hi-tech AI so we can finally sit back and relax while our perfect AI butler makes our bed and does our laundry.
So what can we do about it? Well, companies that are heavily invested in building these robots are trying their best to solve this paradox one task at a time. I would like to propose a divergent solution. Instead of solving the paradox, I think our energy and effort will be much better spent if we bypassed it altogether by changing our approach to building these technologies.
In that spirit, I would like to propose 6 design principles for future robotics that I believe can have a great impact in helping us avoid the Moravec’s trap and building robots with real world utility.
Principle 1: Narrow Technology Focus
In our quest to sidestep Moravec's Paradox and propel robotics into a future of practical utility, the first step is a mantra of 'mastery before versatility.' This approach is all about honing in on a specific task or set of tasks and perfecting them to near perfection before expanding the robot’s repertoire.
The core idea here is specialisation. Just as a master chef excels in culinary arts or a virtuoso in a specific musical instrument, our robots too should aim to achieve unparalleled expertise in their designated functions. It's about creating a robot that isn't a jack of all trades, but a master of one (or a few).
Advantages of Narrow Focus
This focused approach has several advantages:
Efficiency: Specialised robots can perform tasks more efficiently, as they are optimised for specific functions.
Reliability: With a narrow focus, robots are less prone to errors and can deliver consistent results.
Easier Training and Integration: Specialised robots can be trained more easily with specific datasets and integrated into existing systems without the need for wide-ranging adaptability.
Scalability: Once a robot has mastered a specific task, it can be deployed at scale, improving productivity in industries like agriculture, healthcare, or manufacturing.
Previously I had written an article on the benefits of narrow focus when it comes to AI and Robotics. But if you get my point, let’s move onto Principle #2.
Principle 2: Pragmatic Design Over Humanoid Mimicry
Prioritise pragmatic design over humanoid mimicry. This principle is an ode to functional efficiency, challenging the traditional fascination with creating robots that resemble humans in form and function.
The essence of this principle is a shift in design philosophy. Instead of focusing on making robots that look and move like humans, the emphasis is placed on designing robots that are best suited to their tasks, regardless of whether that form resembles anything biological. It’s about choosing the most efficient design for a task, even if it means the robot looks more like a piece of abstract art than a human.
Benefits of Pragmatic Design
This approach to design has several benefits:
Efficiency: Robots designed specifically for tasks can perform them more efficiently than a humanoid robot attempting the same tasks.
Durability and Safety: Task-specific designs can be more durable and safer in certain environments. For example, a robot designed for hazardous material handling would prioritise robustness and precision over humanoid dexterity.
Cost-Effectiveness: Pragmatic designs can often be simpler and more cost-effective to build and maintain than complex humanoid robots.
Innovation in Robotics: This approach encourages innovative thinking, leading to unique design solutions that might not have been considered if the focus was solely on mimicking human form.
Principle 3: Integrating Language Models
Integration of advanced language models into robotics is a move that significantly broadens the scope and utility of our mechanical companions beyond mere physical tasks.
The Power of Language in Robotics
Language is a fundamental aspect of human interaction and intelligence. By integrating sophisticated language models into robots, we enable them to communicate, interact, and even collaborate with humans in ways that were previously the domain of science fiction. This isn’t just about programming pre-set responses; it’s about empowering robots with the ability to understand, interpret, and engage in human language in a dynamic, context-aware manner.
Benefits of Language Integration
Increased Versatility: Language-capable robots can perform a wider range of functions, from customer service to providing companionship.
Improved Human-Robot Interaction: Communication abilities make robots more user-friendly and accessible, bridging the gap between technology and daily human experience.
Enhanced Problem-Solving: With the ability to process and respond to verbal instructions, robots can tackle complex tasks that require understanding and contextual awareness.
A Step Towards True AI Integration
By incorporating language models, we take a significant step towards integrating true artificial intelligence into robotics. This not only enhances the robots' functionality but also opens up new avenues for AI research and application, where robots can learn, adapt, and interact in more human-like ways.
Principle 4: Adaptive Programmable Design
This approach is about creating robots that are not just built for a set of predefined tasks but are inherently designed to be adaptable and customisable through programming.
Adaptive Programmable Design is a philosophy where the core of a robot – its control systems, software interfaces, and basic functionality – is designed with adaptability in mind. This means that the robot can be reprogrammed or reconfigured for different tasks or environments without needing significant hardware modifications.
Imagine a robot initially designed for agricultural purposes, such as monitoring crop health or soil conditions. With Adaptive Programmable Design, this same robot could be repurposed for environmental monitoring, collecting data on air quality or forest health, with minimal changes to its physical structure. All it requires is a change in its software programming and perhaps some minor adjustments to its sensors.
The Role of Modular Design
A key aspect of this approach is modular design. By creating robots with interchangeable parts or modules, the hardware can be easily adapted to different functions. This could mean swapping out a soil sensor for an air quality sensor, or adding a new module for different types of data analysis.
It is important to note however, that modular design is not similar to an all purpose design. Its basically creating a robot using hardware that might specialise in a few use-cases but could be easily tweaked for various purposes using software upgrades and customisability.
Benefits of Adaptive Programmable Design
Cost-Efficiency: Reducing the need for multiple specialised robots, as one robot can adapt to various roles.
Longevity and Sustainability: Extending the useful life of a robot by adapting it to new tasks as needs evolve.
Encourages Innovation: Allowing users, developers, or third parties to create new applications or functionalities for the robot, fostering a collaborative and innovative ecosystem.
Empowering Users Through Open Programming
Adaptive Programmable Design aligns perfectly with open-source principles, where users or developers have access to the robot’s programming interface. This openness not only democratises the use and adaptation of robotics but also spurs a community-driven development model, similar to how open-source software has led to vast innovation in computing.
Principle 5: Simplicity and Sustainability
Now let us bring our focus towards a principle that is often overshadowed in the race for technological sophistication: the power of simplicity and sustainability in robotic design.
Minimalism in Robotics
The mantra here is 'less is more'. This approach advocates for the creation of robots with minimalist design – not in terms of capabilities, but in terms of complexity. It means engineering robots that are straightforward to build, easy to maintain, and uncomplicated in their operation.
The Benefits of Simple Design
Ease of Maintenance and Repair: Simpler designs mean that robots can be maintained and repaired with less effort and expertise. This increases their practicality, especially in less tech-savvy environments.
Cost-Effectiveness: Minimalist designs are often more cost-effective to produce and maintain, making robotic technology more accessible to a wider range of users and industries.
User-Friendly: Simplicity in design translates to ease of use, making robots more approachable and less intimidating for the average person.
Sustainability at the Core
Sustainability is another key facet of this step. It involves designing robots that are not only energy-efficient but also built with recyclability and eco-friendliness in mind. This might mean using materials that are more environmentally friendly or creating robots that can be easily disassembled for recycling at the end of their life cycle.
Principle 6: Open Source Environment
The final principle in my framework is the establishment of an Open Source Environment in robotics, a strategic move that could revolutionise how we interact with and develop robotic technology.
Open Source in Robotics
This approach is about more than just sharing code; it’s about building a community around robotics. By making the software and programming interfaces of robots open source, we invite hobbyists, developers, researchers, and users to contribute to and expand the capabilities of the robots.
Practical Implications and Examples
Imagine a robot designed for environmental monitoring. In an open source environment, this robot’s basic functionalities can be modified and enhanced by a global community of developers. This could lead to the creation of new applications, such as adapting the robot for urban air quality monitoring or for use in agricultural pest control, through community-driven innovation.
Benefits of an Open Source Approach
Accelerated Innovation: Open sourcing accelerates the pace of innovation in robotics, as diverse ideas and perspectives contribute to the development of new functionalities and improvements.
Customisation and Flexibility: Users and developers can customise robots for specific needs, making them more adaptable and versatile.
Community Building: An open source environment fosters a sense of community and collaboration, which can lead to more robust and well-tested solutions.
Addressing Intellectual Property and Quality Concerns
While open sourcing in robotics brings immense opportunities for innovation, it also raises questions about intellectual property and quality control. To address this, the framework can include licensing models that protect the core intellectual property of the hardware while allowing freedom in software development. Additionally, a robust community governance model can ensure that contributions are vetted for quality and reliability.
The Current Trajectory vs. The Proposed Path in Robotics
Currently, in the realm of robotics, there’s a strong fascination with creating machines that mirror human and animal forms and functions. However, this path, while technologically breathtaking, often leads to robots that are more about spectacle than practicality. They can dance, do parkour, and maybe even make a cup of coffee, but when it comes to seamlessly integrating into the multifaceted industry of human tasks, they’re a bit like a fish trying to climb a tree.
The path that I am proposing is less about making humanoids and more about crafting utilitarian tools. This new trajectory focuses on creating robots that are specialised yet adaptable, functionally innovative, and designed with a clear purpose in mind. Instead of teaching our robots to mimic our every move, why not build them to excel in areas where they can truly shine and complement our human capabilities?
By emphasising narrow specialisation, pragmatic design, language model integration, adaptive programmable design, simplicity, and open source environment, we're looking at a future where robots are not just trying to walk in our shoes but are creating their own paths – ones that lead to new, uncharted territories of usefulness and innovation.
Robots are less like futuristic sidekicks and more like indispensable tools – versatile, adaptable, and, most importantly, sensibly integrated into our world. They aren’t just showpieces of what technology can mimic; they are testaments to what technology can achieve when it's guided by thoughtful design and purpose.
