Robotics Q&A: Interview with Carnegie Mellon University's Matthew Johnson-Roberson

The Future of Robotics: A Conversation with Matthew Johnson-Roberson

Over the next few weeks, TechCrunch will be running a series of Q&As with some of the top minds in robotics. One such expert is Matthew Johnson-Roberson, director of the Robotics Institute at Carnegie Mellon University and co-founder and CTO of robotic last-mile delivery startup Refraction AI. In this conversation, we’ll delve into the future of robotics, including the role of generative AI, humanoid robots, and the next major category for robotics.

The Role of Generative AI in Robotics

Generative AI has been making waves in various industries, and its potential applications in robotics are vast. According to Johnson-Roberson, "generative AI will significantly bolster the capabilities of robots." By enabling them to generate novel data and solutions, generative AI can help robots better generalize across a wide range of tasks, enhance their adaptability to new environments, and improve their ability to autonomously learn and evolve.

This is particularly exciting for robotics as it allows robots to navigate complex tasks more efficiently. "Imagine a robot that can learn from experience and adapt to new situations without the need for extensive programming," Johnson-Roberson says. This could be a game-changer in industries such as manufacturing, healthcare, and transportation.

The Humanoid Form Factor: Challenges and Opportunities

Humanoid robots have long been a subject of fascination, with their potential to mimic human movement and interaction sparking excitement among researchers and developers alike. However, Johnson-Roberson notes that the humanoid form factor is "a really complex engineering and design challenge." The desire to mimic human-like movement creates a high bar for actuators and control systems, while also presenting unique challenges in terms of balance and coordination.

Despite these challenges, Johnson-Roberson believes that the humanoid form has the potential to be extremely versatile and intuitively usable in various social and practical contexts. "Mirroring the natural human interface and interaction could make robots more relatable and accessible to humans," he says.

However, it’s likely that other platforms will succeed before humanoids do. Johnson-Roberson notes that "the humanoid form is still a developing area of research, and we’re yet to see significant advancements in terms of scalability, efficiency, and reliability."

The Next Major Category for Robotics

Beyond manufacturing and warehouses, the agricultural sector presents a huge opportunity for robotics to tackle challenges such as labor shortages, efficiency, and sustainability. Transportation and last-mile delivery are also areas where robotics can drive efficiency, reduce costs, and improve service levels.

Johnson-Roberson believes that these domains will likely see accelerated adoption of robotic solutions as technologies mature and regulatory frameworks evolve to support wider deployment. "The next decade might witness significant growth in the agricultural sector, with robots being used for tasks such as crop monitoring, harvesting, and planting," he says.

The Advent of True General-Purpose Robots

The idea of true general-purpose robots capable of performing a wide range of tasks across different environments is still a distant reality. According to Johnson-Roberson, it requires breakthroughs in multiple fields, including AI, machine learning, materials science, and control systems.

However, the journey toward achieving such versatility is a step-by-step process where robots will gradually evolve from being task-specific to being more multi-functional and eventually general-purpose. "The development of true general-purpose robots will likely take decades, if not centuries," Johnson-Roberson says.

Home Robots: Will They Take Off in the Next Decade?

The vision of having a general-purpose domestic robot that can perform various tasks such as cleaning, cooking, and childcare is still a concept that sparks imagination. However, Johnson-Roberson notes that home robots are yet to achieve significant traction in the market.

While there have been advancements in robotic vacuum cleaners and smart speakers, these devices are far from being truly autonomous and capable of performing complex tasks. "The next decade might see incremental improvements in home robots, but it’s unlikely that they will become a mainstream phenomenon," Johnson-Roberson says.

Conclusion

As we look to the future of robotics, it’s clear that there are both exciting opportunities and significant challenges ahead. From the role of generative AI to the development of humanoid robots, the industry is pushing the boundaries of what’s possible.

While we may not see significant advancements in all areas simultaneously, Johnson-Roberson’s insights offer a glimpse into the potential of robotics to transform industries such as manufacturing, healthcare, and transportation.
