By age eight, he was trying to build computers using whatever he could get his hands on, such as switches, relays, light bulbs, and batteries. He was self-taught and learned from books and whatever he could read. He built a machine that could play tic-tac-toe and not be beaten by 1967. He read science fiction and anything he could find that talked about computers. He was particularly influenced by the movie 2001: A Space Odyssey, which sparked his interest in artificial intelligence. In high school, he had two math teachers who took a special interest in him and helped him get more materials. He did his undergraduate degree in pure mathematics at Flinders University of South Australia, taking 39 courses in mathematics and only one physics and one chemistry course. He was influenced by a faculty member, Bill Cornish, who took him under his wing in abstract algebra. He also had access to the university’s mainframe computer, where he spent 12 hours every Sunday teaching himself computer science. He wrote his first program in Fortran, which simulated a neuron talking to another neuron. He also built a physical neural network that could learn by using electrodes in copper sulfate in an ice cube tray.
Contributions to AI: Rodney Brooks’ contributions to the field of artificial intelligence include his work on: Behavior-based robotics: Developing robots that use simple behaviors to interact with their environment, rather than relying on complex planning and reasoning. Subsumption architecture: A control architecture for robots that allows them to exhibit multiple behaviors simultaneously, with higher-level behaviors subsuming lower-level behaviors when necessary. Situated cognition: The idea that intelligence is situated in the body and the environment, and that robots should be able to learn and adapt to their environment through interaction. His work has had a significant impact on the field of robotics and has inspired many researchers to develop new approaches to building intelligent robots.

00:25:21 Evolutionary Robotics and Embodiment in AI
Origins of the Behavioral-Based Robot Approach: In the mid-80s, the dominant approach in AI and robotics was sense, model, plan, and act. Brooks argued that this approach was too slow and inflexible for dynamic environments. Instead, he proposed a reactive, behavior-based approach that directly linked sensors to actuators, bypassing the need for a detailed world model.
Inspiration from Insects: Brooks drew inspiration from insects, which can exhibit complex behaviors despite having relatively simple nervous systems. He observed insects in rural Thailand and wondered how they could produce such sophisticated behaviors with limited computational resources.
Embodied and Situated Robots: Brooks emphasized the importance of building robots that were embodied and situated in the environment. He argued that simulations are doomed to succeed because they allow researchers to simplify the problem and hide the fake stuff. Real-world robots must deal with the complexities of physics and the unpredictability of the environment.
Building from the Bottom Up: Brooks advocated for a bottom-up approach to building robots, starting with simple systems and gradually adding complexity. This approach allowed him to explore how complex behaviors could emerge from simple building blocks.
Subsumption Architecture: Brooks developed the subsumption architecture, a control architecture for robots that is based on a cartoon version of evolution. The architecture consists of a hierarchy of layers, with each layer responsible for a specific behavior. Higher layers can subsume the behaviors of lower layers, allowing for more complex behaviors to emerge.
Influences from Cybernetics: Brooks was influenced by the work of Ray Walters, who built simple robots using vacuum tubes. These robots exhibited complex behaviors despite their limited computational resources. Brooks’ early experiments with building robots as a teenager also influenced his approach to robotics.
Philosophical Influences: Rodney Brooks was influenced by philosophers who criticized traditional symbolic AI, such as Hubert Dreyfus. Brooks’ approach to robotics is not based on German philosophy or phenomenology, but he did have students who were engaged with that work.

00:39:49 Philosophy and Robotics: The Interwoven Journey of Rodney Brooks
Rodney Brooks’ Exposure to Phenomenology: As a graduate student, Rodney Brooks studied German philosophy, including Heidegger and Husserl, through a class taught by Rodney Flores. Brooks found the philosophy challenging but gained an understanding of phenomenology and its ideas.
Phenomenology’s Influence on Brooks’ Work: Brooks was inspired by the phenomenological concept of “ready-at-hand,” which aligned with J.J. Gibson’s idea of affordances, emphasizing how objects communicate their intended use through their design. This concept resonated with Brooks’ approach of direct coupling between perception and action, guiding behavior based on perceived affordances.
Critique of Searle’s Argument: Brooks disagreed with Searle’s philosophical argument that machines could not possess true intelligence or understanding. Brooks maintained that biological entities are also machines, subject to the same physical forces and principles as non-biological entities. He believed Searle’s argument relied on invoking a higher order of existence that modern science does not support.
Perception and Action Coupling: Brooks viewed phenomenology as a framework for understanding how perception and action could exist in the world without relying on a central world model or a simulation of reality. This perspective influenced his approach to robotics, emphasizing the importance of direct coupling between perception and action, allowing robots to respond effectively to their environment.
Influence on Students: Brooks’ students, David Chapman and Phil Agre, embraced phenomenology more strongly, incorporating these ideas into their PhD theses. Chapman and Agre actively engaged in the simulation of adaptive behavior group and artificial life groups, contributing to intellectual discussions across continents.

00:58:08 Emergent Properties in AI: A Historical Perspective
The Nature of Emergence: Rodney Brooks emphasizes the concept of emergence in systems, particularly complex natural systems like the brain. He explains that emergent properties arise from the interactions of multiple subsystems, not from any single component or “magic” element. Brooks highlights the example of a gasoline-driven car, where the ability to drive on the freeway is an emergent property of the various components working together, not any specific part.
Reductionist Engineering and Emergence: Brooks discusses the challenges of engineering complex systems using reductionist methods, which involve decomposing the system into smaller parts. He argues that reductionist approaches often struggle to capture the emergent properties that arise from the interactions of these parts. Brooks emphasizes the need to encode the emergence somehow in reductionist analysis and acknowledges that this can be a challenging task.
Decomposition and Understanding: Brooks raises concerns about how the decomposition of natural systems into parts can bias our understanding of their emergent properties. He mentions the example of neuroscience, where the focus on neurons led to a neglect of the role played by other cells in the brain, such as those that hold the brain together. Brooks stresses the importance of considering the totality and wholeness of a system when studying its emergence.
Changing Landscape of AI Research: Brooks reflects on the changing approaches and emphases in AI research between 1990 and 2010, before the rise of deep learning. He highlights the popularity of various learning mechanisms during this period, including neural networks, support vector machines, and reinforcement learning.

Abstract
Rodney Brooks: Shaping the Future of Robotics and AI
Rodney Brooks, a trailblazer in robotics and artificial intelligence, began his remarkable journey in Adelaide, Australia, in December 1954. Growing up in Australia until he was 22 and a half years old, his fascination for arithmetic and mathematics led him to build computers from an early age. Rodney’s academic pursuits took him to Stanford University in the United States, where he pursued his Ph.D. thesis on computer vision. Post-doctorate, he made significant contributions at CMU and returned to Stanford in 1983. During these formative years, Rodney developed a LISP system for early Sun workstations and drew inspiration from the movie “2001: A Space Odyssey,” particularly the portrayal of HAL’s AI, which would later influence his shift towards humanoid robots.
Innovations in Robotics: Rodney Brooks’ Transformative Journey
Rodney Brooks was exposed to phenomenology during his graduate studies, a philosophical approach emphasizing the lived experience of individuals and their direct engagement with the world. The phenomenological concept of “ready-at-hand” objects guided his approach to behavior-based AI, which emphasized the direct coupling between perception and action, rather than relying on abstract representations.
Rodney Brooks’ involvement in artificial life and adaptive behavior communities influenced his perspective on intelligence and the goals of AI. He questioned traditional AI approaches that focused on creating human-level intelligence and emphasized the importance of understanding how to replicate human capabilities. His early papers, including “Intelligence without Representation” and “Intelligence without Reason,” challenged conventional AI concepts and generated significant debate. These contributions earned him the Computers and Thought Award in 1991.
Revolutionizing AI with Behavior-Based Robotics
A pivotal moment in Rodney’s career came with the development of the subsumption architecture, inspired by the efficient movement of insects. This innovation allowed robots to navigate complex environments using minimal computational resources. Rodney’s endeavors in behavior-based AI significantly influenced the field, challenging the traditional sense-model-plan-act approach and emphasizing reactive, embodied systems directly interacting with the world. Rodney’s philosophy was influenced by interdisciplinary research, including Lucy Suchman’s work and Japanese researchers in the fields of simulation of adaptive behavior and artificial life.
In 1984, Rodney Brooks co-founded Lucid, a startup in Silicon Valley. The company initially focused on developing a Lisp compiler. Brooks secured venture funding and used an advance from a book sale as a down payment on a house in Lexington, Massachusetts. He continued working on the compiler while teaching at MIT and pursuing other research. The compiler project spanned eight years, with updates sent via cartridge tape across the country. Lucid targeted multiple computer architectures due to the fragmented market at the time. Despite initial success, investors expressed concerns about the Lisp business. Lucid shifted its focus to developing an interactive debugging environment called Cadillac. The system aimed to be comprehensive, leading to a high price point of $20,000 per seat. The company faced competition from Borland, which offered a more affordable and streamlined system. Ultimately, Lucid went out of business due to pricing and customer-related challenges.
Pioneering Contributions: From Mars Rovers to Household Robotics
Rodney’s career is marked by a series of innovative partnerships and projects. Facing NASA’s initial reluctance, he successfully landed the Sojourner rover on Mars in 1997. However, it was the unexpected commercial success of the iRobot Roomba vacuum cleaner, selling millions of units, that brought his work into everyday homes. Rodney’s insights into the limitations of increased intelligence in robotics, notably in complex tasks like developing humanoid robots, have been crucial in understanding the realistic capabilities and future of AI.
iRobot: Rodney Brooks’ Journey through Collaborative Robotics iRobot was initially known as IS Robotics, a company founded with the purpose of developing and sending small rovers to explore other planets. Collaborations with Ballistic Missile Defense Organization and NASA led to the placement of an older project on Mars. iRobot experimented with numerous business models without venture capital involvement. The company sold research robots to universities, partnered with the Japanese government for nuclear power plant inspection robots, and collaborated with Hasbro to build robot toys in China. iRobot gained significant revenue from the defense department, leading to the development of PackBot robots. The Roomba, a robotic vacuum cleaner, was introduced to the market in 2002 and achieved great success. PackBot robots were deployed at the 9-11 site, assisting in search and rescue operations. They were also used in Afghanistan and Iraq to detect weapons caches and defuse roadside bombs, protecting bomb technicians. PackBot’s contribution at the Fukushima nuclear plant was notable, where it aided in the decommissioning process and provided vital information in highly radioactive areas. Rodney Brooks departed from iRobot in 2011 after 21 years, seeking a hands-on approach in a smaller organization. He recognized the changing labor landscape in China and the need for collaborative robotics to supplement human workers. Heartland/Rethink was established with the aim of integrating robots and people in manufacturing facilities, improving productivity, and enabling local production.
