Instead of computation as the ultimate conceptual metaphor that helped artificial intelligence become a separate discipline in the scientific community, he proposed that action or behavior are more appropriate to be used in robotics. Critical of applying the computational metaphor, even to the fields where the action metaphor is more appropriate, he wrote that:
Some of my colleagues have managed to recast Pluto's orbital behavior as the body itself carrying out computations on forces that apply to it. I think we are perhaps better off using Newtonian mechanics to understand and predict the orbits of planets and others. It is so much simpler.
In his 1990 paper, "Elephants Don't Play Chess", Brooks argued that in order for robots to accomplish everyday tasks in an environment shared by humans, their higher cognitive abilities, including abstract thinking emulated by symbolic reasoning, need to be based on the primarily sensory-motor coupling with the environment, complemented by the proprioceptive sense which is a key component in hand–eye coordination, pointing out that:
Over time there's been a realization that vision, sound-processing, and early language are maybe the keys to how our brain is organized.
;Editor positions Brooks was also co-founding editor of the International Journal of Computer Vision and is on the editorial boards of various journals including:
Brooks was an entrepreneur before leaving academia to found Rethink Robotics. He was one of ten founders of Lucid Inc., and worked with them until the company's closure in 1993. Before Lucid closed, Brooks had founded iRobot with former students Colin Angle and Helen Greiner.
Robots
He experimented with off-the-shelf components, such as Fischertechnik and Lego, and tried to make robots self-replicate by putting together clones of themselves using the components. His robots include mini-robots used in oil wells explorations without cables, the robots that searched for survivors at Ground Zero in New York, and the robots used in medicine doing robotic surgery. ;Allen In the late 1980s, Brooks and his team introduced Allen, a robot using subsumption architecture. Brooks' work focuses on engineering intelligent robots to operate in unstructured environments, and understanding human intelligence through building humanoid robots. ;Baxter Introduced in 2012 by Rethink Robotics, an industrial robot named Baxter was intended as the robotic analogue of the early personal computer designed to safely interact with neighboring human workers and be programmable for the performance of simple tasks. The robot stopped if it encountered a human in the way of its robotic arm and has a prominent off switch which its human partner can push if necessary. Costs were projected to be the equivalent of a worker making $4 an hour.
