What is AI Robotics? Understanding Intelligent Machines

Artificial intelligence (AI), computer science, and robotics are continuously evolving scientific fields that have the potential to completely revolutionize numerous aspects of our lives, from agriculture to healthcare. 

Nowhere is this more evident than in AI robotics, where the immense power of intelligent machines and artificial intelligence systems combine to allow robots to observe, learn, reason, and interact with the world around them.

This blog will provide an in-depth introduction to the application of AI in robotics, delving into their origins, present use cases, and future advancements. From more complex tasks to simple, repetitive tasks, we can train robots to help human beings with just about anything. So, let’s dive in and find out how.

The 4 key components of AI robotics

In this section, we will outline the four major components often used within the artificial intelligence robotics field. 

1. Perception

Much like our own five senses, AI robots use sensors, such as LiDAR, sonar, cameras, ultrasonic, and radar, to gather and interpret data from their environment.

These sensors can capture visual, audio, and tactile inputs, allowing robots to:

  • Recognize objects.
  • Navigate their surroundings.
  • Interpret human gestures and speech.

2. Learning and adaptation

AI robots have the incredible ability to continuously learn from various data sources and adapt their behavior accordingly, eliminating the need for constant human intervention. This can be done by using two different types of ‘learning’:

  1. Machine learning algorithms: These models can analyze vast amounts of data and recognize patterns within the information. This allows these sophisticated machines to improve their performance over time. 
  2. Reinforcement learning algorithms: This model allows robots to learn through repetitive trial and error, optimizing their actions based on feedback from the environment.

A brief history of AI robotics

The history of AI robotics is truly fascinating, full of scientific discoveries, technological breakthroughs, and visionary minds that have shaped the development of intelligent machines. 

Let’s journey through time to explore the key milestones and advancements that have led us to the present state of AI robotics.

Early beginnings (1940s-1950s)

The roots of AI robotics can be traced back to the early days of computing and artificial intelligence.

In the 1940s, mathematician and logician Alan Turing proposed the concept of a “universal machine” which could simulate the operations of any other machine. This theorized technology laid the basic foundation for a computer that could demonstrate artificial intelligence.

In the 1950s, researchers such as John McCarthy, Marvin Minsky, and Claude Shannon significantly contributed to this newly developing field of study. This included the development of complex neural networks that have a similar architecture to the human brain and introducing the concept of machine learning.

Robotics emerges (1960s-1970s)

The 1960s saw the emergence of robotics as a prominent field of study. The introduction of the term ‘robotics’ is often attributed to Isaac Asimov, a renowned science fiction writer who wrote such literary classics as I,Robot, Foundation, and The Caves Of Steel.

The rise of autonomous robots (1980s-1990s)

The 1980s saw significant advancements in AI robotics, particularly in automation. Research efforts shifted towards developing autonomous systems capable of perceiving and interacting with their environment without human intervention.  

The most revolutionary achievement during this period was the development of the Shakey robot at Stanford Research Institute, which could navigate and perform tasks in dynamic environments.

At this time, we also saw the emergence of mobile robots equipped with vision systems for object recognition and navigation.

Reinforcement learning and cognitive robotics (2000s-2010s)

At the start of the millennium, researchers focused on machine learning and the cognitive capabilities of robotics. Reinforcement learning gained popularity as a technique for training robots to learn from trial and error, optimizing their behavior through environmental feedback. 

Cognitive robotics, inspired by human intelligence, aimed to create robots with higher-level thinking abilities, such as perception, attention, and memory.

Deep learning and humanoid robots (2020s)

The recent era of robotics has been full of remarkable advancements in deep learning and the development of humanoid robots. 

Deep learning, fueled by the availability of big data points and increased computational power, has drastically improved the intellectual capabilities of artificial intelligence. At the same time, complex convolutional neural networks have enabled robots to effectively perform perception tasks, such as object recognition and image understanding. 

Humanoid robots, designed to resemble and interact with humans, have also gained much attention. Examples include Honda’s ASIMO and Boston Dynamics’ Atlas, which demonstrate advanced locomotion, manipulation, and human-robot interaction capabilities.
