What Exactly is Robotics?

In simple terms, robotics refers to the science and engineering behind conceiving, designing, building, programming and applying robots – automated intelligent machines that can perform human-like physical tasks or cognitive functions.

Offering precise definitions, the Institute of Electrical and Electronics Engineers (IEEE) states robotics aims to "replace a human worker, operate independently of humans, solve mathematical problems algorithmically, walk in various patterns or even make its own decisions."

The word robot too has an interesting background. It comes from the Czech word "robota" meaning forced labor. Czech playright Karel Capek first used "robot" in 1920 in the play RUR (Rossum’s Universal Robots) which envisioned a factory mass producing synthetic people called robots!

So while the initial connotation was mechanical, robotic systems have now evolved far beyond basic automation. They are complex cyber-physical systems combining advanced mechanics, electronics, software and cutting-edge technologies like AI/ML, computer vision and 5G connectivity to manifest tasks earlier considered too complex for machines.

Having understood the fundamental concept now, let me walk you through a brief history before diving into robot components, applications and benefits.

The Winding Path of Robotics Evolution

Our early ancestors’ fascination with engineering automated machines dates back thousands of years…

700 BC – Texts from ancient Greece, China and India mention robotic servants and automated wine servers!

1495 AD – The first humanoid robot called the Mechanical Knight created by Leonardo Da Vinci offered a glimpse into the Italian genius inventor’s extraordinary imagination.

1738 AD – The writer Pierre Jaquet-Droz and his son built highly complex android-like automata that could pen custom texts and drawings input by users. A sign of things to come!

1961 AD – American inventor George Devol designed the very first digitally operated robot arm called Unimate that worked on a GM assembly line. This marked robotics transition from novelty to industrial and commercial viability.

1966 AD – SHAKEY created by Stanford Research Institute became the pioneering first mobile robot with the ability to determine actions by itself based on visual interpretation of situations.

1997 AD – NASA’s Pathfinder mission deployed Sojourner, the first robotic Mars rover demonstrating exciting space exploration capabilities. Honda’s humanoid P2 robot could also walk unaided on two feet this year.

2011 AD – The first robotic surgery with haptic feedback allowing surgeons to ‘feel’ instruments was tested successfully at UC Santa Cruz.

2018 AD – Boston Dynamics released videos of its walking humanoid bot Atlas effortlessly jumping over obstacles without loss of balance – indicating major strides in replicating biped locomotion.

2021 AD – AutoX became the first fully driverless robotaxi service without any humans present to serve mandatory overrides, launched in Shenzhen China.

Current State of Robotics – Today robotic systems are assisting humans across applications like factories, warehouses, retail, hospitality, healthcare, agriculture, defense/security services and more. Rapid 5G rollout is expected to accelerate robotics adoption manifold.

As you may notice, while early tinkering with automatons focused largely on aesthetics, recreation or mimicking mobility – the explosion of computing power over the past few decades has enabled robots to take on far more meaningful and impactful applications.

But what exactly comprises these intelligent bots? Let‘s analyze next…

Anatomy of a Robot – Mind, Body and Senses

Just like humans, most robotic systems have key components that work harmoniously to manifest functional behavior:

The Mechanical Body & Limbs

The visible external covering or framework of a robot – designed appropriately for the device’s functional purpose – is called its body or shell.

• Humanoid bots like Sophia have plastic or rubber synthetic skin over metal and aluminum frames that replicate an almost eerily real appearance and tactile feel.

• Drones used in agriculture have durable yet lightweight frames to enable flight capacity.

• Industrial bots feature metallic bodies for heavy loads bearing ability and long term endurance in factories.

Most bots also have limbs or appendages attached to the main body. Robot arms/grippers pick and place objects, humanoids have moving legs, drones have flight propellers.

Internal skeletal structures like joints offer mobility using electromechanical actuators – rotors, pistons and gears that generate precise physical motion control.

The Electrical Nervous System

This is the complex network of wires and circuit boards functioning like arteries and nerves that electrically link all the sensory devices, computing modules, battery packs and actuators. Information signals and power transmission happens through this system allowing a coordinated, optimized response.

The Powerhouse

Robots need energy! Batteries, electric power supplies or petrol/diesel reservoirs enable movement. Having adequate energy storage and minimal charging downtime allows longer working durations. Solar or hydrogen fuel cells are growing in popularity as well.

The Sensory Organs

Cameras, radars, lidars, thermal sensors, pressure monitors etc. act like eyes and ears, providing critical inputs on ambient conditions. This environmental perception and feedback is then utilized to guide the device’s navigation and actions.

The Brain

The central processing unit or computer brain analyzes incoming video, sensor data and remote inputs to plan and direct operations via algorithm execution. With deep learning integration, some advanced bots can teach themselves as well from operational data through neural network feedback loops.

So in summary, a robot’s physical components offer mobility while the senors observe environments and the electronic nervous system transports this information to the computer brain directing actuator movements using programming logic. Pretty cool!

But how exactly are these bots coded for functionality? Let‘s analyze different programming approaches…

Rule-Based vs Learning Based AI

Another crucial aspect that defines robotic behavior is the software intelligence integrated into these machines.

Broadly speaking there are 2 methods of adding Artificial Intelligence into the robots’ operating systems:

1. Rule/Heuristic-based Programming

Here developers define and input specific logical decision rules that map sensor signals and situational data to executable actions in a predefined manner.

For example in a delivery bot, code rules that:

IF obstacle detected ahead THEN initiate immediate stop.

So the robot cannot deviate from developer instructions in the code. This limits flexibility in dealing with complex unknown scenarios.

Many operational industrial and commercial robots use rule-based programming for predictable outcomes.

2. Machine Learning-based AI

In this approach, instead of hard-coded rules, developers create deep neural networks and use datasets to train the models to take autonomous decisions mimicking human-like reasoning visual recognition capabilities.

By absorbing volumes of sensor streams, information and outcomes on an ongoing basis, ML algorithms can continuously fine-tune actions without explicit programming thus handling ambiguity far better.

Over time, the bot’s decision making becomes extremely sophisticated and dynamic like a human driver alertly reacting to real-time road conditions.

Advanced robots like self-driving cars predominantly use learning-based AI for improved adaptable results, though the initial training process is resource intensive.

The quest for General or Human-Level AI – beyond task-based narrow intelligence – also utilizes neural networks based deep learning. This remains a key area of innovation focus currently in robotics.

Now that you understand everything under the hood, let me walk you through the incredible ways robotics is already transforming human lives…

Wall Street too relies on intelligent algorithms running High Frequency Trading systems that leverage AI to execute equity, derivatives and cryptocurrency transactions far faster than humans can comprehend often making millions in microseconds for investment banks.

While regulators are increasingly watchful of market volatility from cascade effects, demand continues for such automation. AI virtual assistants are entering consumer mobile banking apps as well.

Defense/Law Enforcement Applications

Police forces are assisted by aerial drones for surveillance, cargo inspection at ports also uses radiation detection bots while bomb defusing remotely controlled units minimize risks. Bots help soldiers carry heavy weaponry loads reducing combat fatigue.

Controversially there is also growing investment in developing autonomous weapons systems – aerial and submarine drones that can identify and precision strike targets based on algorithms. Though various groups advocate for global AI weapon treaties given ethical risks.

Other novel applications..

From inventory auditing robots in offshore oil rigs that improve workplace safety to rice seeding drones that can help aging Asian farmers improve crop yields and reduce labor shortages to ChatGPT style creative writing bots now composed copy or generated music faster – the use cases for applied robotics keeps expanding!

Quantifiable Business Impacts

Given these wide ranging applications, what are some measurable benefits intelligent robots offer?

60% higher productivity on average

Automating repetitive, mundane factory shopfloor and warehouse tasks with precise bots improves yield rates and uptime considerably while eliminating human fatigue or errors. Findings from an MIT study highlight the immense productivity potential:

80% jump in warehouse storage density

Logistics firms using warehousing bots achieve upwards of 80% increase in storage density due to the bots’ ability to operate in narrower spaces and stack pallets much higher unlike human operators limited by access conditions.

30% decline in customer service costs

Chatbots and voicebots now handle 30% of initial customer engagement for many firms given their 24/7 availability. This has led to significant drops in service costs by reducing volumes going to human agents.

90% accuracy in Kinect guided stroke rehabilitation therapy

Allowing remote patient monitoring, University of Auckland researchers have developed a machine learning algorithm that accurately evaluates rehabilitation exercises done at home using Kinect motion sensors. Completing assignments reliably is vital for recovery.

The above are just some representative examples across industries highlighting the operational and financial upside generated by intelligently integrating automation levers like robotics, especially for high frequency repetitive tasks earlier performed manually.

Adoption is only expected to multiply as robot prices drop, end-user experience enhances and connectivity improves. IDC predicts almost 30% of all warehouse pick and place operations will be automated by 2025 given ROIs under 12 months in many cases!

The Inexorable March of Automation

Adoption rates continue ticking higher as capabilities expand across services sectors. Today robotics advancement seems inexorable and in just the next decade, transformations currently unimaginable will impact businesses globally.

Healthcare will achieve new care delivery breakthroughs by converging biomedical engineering with AI, 5G remote instrumentation and nanotech advances.

As digital assistants turn ubiquitous across smart homes to enterprise advisors, the next frontier will be applications mimicking creativity, emotional intelligence and interpersonal skills once considered uniquely human. Early examples already exist!

Cloud robotics allowing sharing of vast distributed experiences in real-time presages decentralized swarm intelligence cooperating on collective goals the way natural systems operate. This offers a sustainable model for managing lifecycle costs as well. Regulatory emphasis on safety and ethics will however be vital as programming bias can amplify.

While the onset of hyperautomation triggers transitions with some traditional skills getting obsolete or jobs transforming, we must also visualize the immense opportunities from freeing up human efforts for solving higher value problems. Just like mechanization boosted productivity in earlier industrial revolutions!

The good news is that enterprises have ample runway now to assess change impact and reorient workforces through reskilling. Maintaining trust via transparency and job mobility support will be key.

As economists Erik Brynjolfsson and Andrew McAfee posit – the AI revolution must be guided deliberately as part of a “grand partnership between minds and machines with people still firmly in charge.”
