Computer Science Keypoints: Fundamentals of Robotics

This introduction will delve into the definition of robotics, its main components, types of robots, application areas, as well as the advantages and disadvantages of employing robots.

Definition of Robotics

Robotics is the branch of technology that deals with the design, construction, operation, and application of robots. Robots, in this context, are programmable machines capable of carrying out a range of tasks autonomously or under human supervision.

Main Components of Robotics

(iii) Control System: The control system in robotics refers to the brain of the robot, consisting of hardware and software that governs its actions. It processes sensory data and issues commands to the actuators.

Example: In a robotic arm used in manufacturing, the control system interprets instructions from the user or a pre-programmed sequence to manipulate objects on an assembly line.

Sensors: Sensors enable robots to perceive and interact with their environment by detecting various stimuli such as light, sound, temperature, proximity, and touch.

Example: In autonomous vehicles, sensors like LiDAR, cameras, and radar collect data about the vehicle’s surroundings, enabling it to navigate safely.

Actuators: Actuators are mechanisms responsible for moving or controlling the robot’s components. These can include motors, pneumatic cylinders, hydraulic systems, and more.

Example: In a robotic prosthetic limb, actuators mimic human muscle movements, allowing the user to perform tasks like grasping objects.

Power Supply: Robots require a power source to operate, which could be electrical, hydraulic, pneumatic, or a combination thereof, depending on the application.

Example: Unmanned aerial vehicles (UAVs) are powered by rechargeable batteries or fuel cells, providing the energy needed for flight.

End Effectors: End effectors are tools or devices attached to the end of a robot’s arm or manipulator, allowing it to perform specific tasks.

Example: In industrial robots used for welding, the end effector may be a welding torch that fuses metal parts together.

Types of Robots

(iv) Humanoid Robots: These robots resemble humans in form and behavior to varying degrees, with articulated limbs and often a head and torso.

Example: Sophia, developed by Hanson Robotics, is a humanoid robot capable of conversation and expressing emotions.

Autonomous Robots: Autonomous robots operate independently of human control, making decisions based on programmed algorithms and sensory input.

Example: Roomba vacuum cleaners navigate through a room, avoiding obstacles and cleaning floors autonomously.

Teleoperated Robots: These robots are controlled remotely by a human operator, typically via a wireless connection.

Example: Surgical robots like the da Vinci Surgical System enable surgeons to perform minimally invasive procedures with enhanced precision.

Augmenting Robots: Augmenting robots enhance human capabilities rather than replace them entirely, assisting individuals in various tasks.

Example: Exoskeletons are wearable robotic devices that support and enhance human strength and endurance, aiding in tasks like lifting heavy objects.

Application Areas of Robotics

(v) Logistics: Robots are used in warehouses for sorting, packing, and transporting goods, optimizing supply chain operations.

Example: Amazon’s fulfillment centers utilize robots like Kiva Systems’ automated guided vehicles (AGVs) to efficiently manage inventory.

Manufacturing: Industrial robots automate repetitive tasks on assembly lines, increasing productivity and precision in manufacturing processes.

Example: Automotive companies employ robots for welding, painting, and assembling vehicle components.

Home: Domestic robots assist with household chores such as cleaning, mowing the lawn, and monitoring home security.

Example: The iRobot Roomba is a popular autonomous vacuum cleaner that navigates through homes, cleaning floors without human intervention.

Travel: Autonomous vehicles, including self-driving cars and drones, offer efficient and safe transportation options.

Example: Waymo, a subsidiary of Alphabet Inc., develops self-driving cars equipped with sensors and AI technology for navigating roads.

Healthcare: Robots are utilized in healthcare settings for tasks like surgery, rehabilitation, medication management, and patient care.

Example: The Intuitive Surgical’s da Vinci Surgical System assists surgeons in performing minimally invasive surgeries with enhanced precision.

Security: Robots enhance security measures by patrolling areas, monitoring surveillance feeds, and detecting potential threats.

Example: The Knightscope K5 robot patrols areas like parking lots and shopping malls, equipped with cameras and sensors to detect suspicious activity.

Space Exploration: Robots play a crucial role in space exploration by conducting research, building structures, and collecting data in environments unsuitable for humans.

Example: NASA’s Mars rovers, such as Curiosity and Perseverance, explore the Martian surface, collecting samples and studying the terrain.

Entertainment: Robots entertain and engage audiences through performances, interactive experiences, and virtual simulations.

Example: Disney’s animatronic characters, like those in the “Pirates of the Caribbean” ride, provide immersive entertainment experiences at theme parks.

Agriculture: Agricultural robots assist farmers in planting, harvesting, monitoring crops, and managing livestock.

Example: Harvest Automation’s HV-100 robots autonomously move potted plants in nurseries, increasing efficiency and reducing labor costs.

Food Preparation: Robots are used in food processing and preparation, improving efficiency and consistency in food production.

Example: Miso Robotics’ Flippy robot assists chefs in commercial kitchens by flipping burgers and frying foods.

Military: Military robots perform reconnaissance, surveillance, bomb disposal, and combat operations, reducing risks to human soldiers.

Example: The Boston Dynamics’ Spot robot is utilized by various military forces for reconnaissance missions and carrying payloads in challenging terrains.

Customer Service: Robots are employed in customer service roles, providing information, assistance, and support to consumers.

Example: SoftBank’s Pepper robot interacts with customers in retail stores, answering questions and providing product recommendations.

Advantages and Disadvantages of Robots

(vi) Advantages:

  • Increased productivity and efficiency in tasks
  • Precision and consistency in operations
  • Ability to work in hazardous or challenging environments
  • Reduction of labor costs and repetitive strain injuries
  • Improved quality of life through automation of mundane tasks


  • Initial high costs of implementation and maintenance
  • Potential job displacement and economic disruptions
  • Dependence on technology, susceptibility to malfunctions or hacking
  • Ethical concerns regarding autonomy and decision-making capabilities
  • Social implications, including privacy issues and inequality in access to technology

In conclusion, robotics continues to revolutionize various industries and aspects of daily life, offering numerous benefits while also posing challenges and ethical considerations. Understanding the fundamentals of robotics is crucial for navigating its evolving landscape and harnessing its potential for positive impact.
