Since the first use of the word ‘robot’ more than a century ago in a sci-fi play, robotic automation has transformed from fiction to reality. With a global market size of $72.17 billion in 2022, the robotics industry is estimated to exceed $283.19 billion by 2032.

Robots are autonomous machines that mimic human actions with enhanced accuracy and safety. While robots are used in several industries, they are especially beneficial in demanding fields such as manufacturing and logistics.

With a combination of sensor technology, machine learning (ML), and artificial intelligence (AI), robotics is set to become the most powerful technology in history.

Among these technologies, sensors constitute the core of robotics. Sensors are the “eyes and ears” of robots, allowing them to sense and navigate the outside world. Additionally, smart sensors have led to adaptive robotics, integrating emerging tech like ML and AI to expand robotic capabilities.

In this article, we explore the role of sensors in robotic automation and how emerging technologies enable them to become intelligent and adaptable.

The Essence of Sensors

From conventional robotic systems to the most recent collaborative robots, also known as "cobots," robots depend heavily on sensors that produce increasingly vast amounts of diverse data.

Sensors serve a function similar to human sensory organs. Just like we use our senses to perceive ourselves and our surroundings, sensors help robots make heads and tails of their environment and perform different tasks such as navigation, collision avoidance, obstacle detection, and distance measurement.

These devices are designed to gather data from the environment and convert it into usable information for the robot's control system. This real-time data collection equips robots with the intelligence to make informed decisions on the spot, just like humans.

Applications of Sensors in Adaptive Robotics

Although traditionally robots have been used in static, isolated workspaces to perform preplanned and repetitive work, this is changing thanks to smart sensors. Sensors integrated with ML and AI become smart, enabling robots to ‘learn’ from real-time data and act accordingly. While smart sensors have several applications, here are some examples that demonstrate their potential:

Manufacturing with Enhanced Safety using Cobots

Cobots can be employed alongside humans for diverse manufacturing applications, including assembly, welding, and quality inspection assignments. In industries, robots often work near humans, requiring a high level of safety. Sensors act as robot "eyes," spotting obstacles or people. On detection, the sensor signals the robot to stop or adjust its path, averting accidents and promoting a smooth human-robot coexistence.

Precision in Autonomous Vehicles

Sensors serve as the cornerstones of autonomous vehicles, guiding them through complex landscapes. For instance, LiDAR sensors emit lasers, reflecting off objects to form data. This data creates a precise 2D or 3D map, helping the vehicle detect obstacles and pedestrians with remarkable accuracy.

Smart Logistics Robots

In warehouses and distribution centers, logistics robots are used to carry, transport, and pack goods. They rely on sensors for mapping, navigation, and collision avoidance. Formerly restricted to fixed routes, they can now adjust paths based on surroundings, using infrared, laser distance, and LiDAR sensing.

Dynamic Decision-Making

Smart sensors make robots intelligent entities capable of dynamic decision-making. Take, for instance, a robot with intelligent sensors navigating through a cluttered space. The sensors continuously scan the changing environment, feeding data to the robot's algorithms. It then performs real-time path calculations and changes its course when required.

Benefits of Integrating Sensors with ML and AI

Coupled with ML and AI, smart sensors give rise to adaptive robotics, driving automation to new heights. ML helps robots learn from experience and adapt to changing work scenarios while AI can be used to make accurate decisions using real-time data.

Some of the benefits of adaptive robotics are as follows:

• Efficiency - Integrating AI and ML in robotics enhances task efficiency, freeing humans for complex roles and fostering innovation.

• Accuracy - Improved accuracy minimizes errors, monitors progress, and ensures safe handling of hazardous materials.

• Adaptability – Adaptive sensors enable robots to flexibly handle various tasks across industries.

• Forecasting - Predictive maintenance driven by AI and ML reduces downtime and costs.

• Enhanced Decision-Making - Robots equipped with AI and ML excel in data analysis, pattern recognition, and informed decision-making.

• Safety - Intelligent sensors provide a safe working environment.
