The need for humans in hazardous jobs has been minimized through these technologies, enhancing workplace safety, while making processes more streamlined and innovative. Ultimately, these improvements translate to cheaper prices and better products for the consumer.
Let’s talk about in this blog what are the eight key parts that make up every robot.
Eight Components of Robots Explained
1. Sensors
Some of the key components of robotics include sensors, which act as a robot’s eyes and ears. They help a robot to adapt to its environment by collecting data about the distance, temperature, light levels, and obstacles around it. Cameras, infrared sensors, ultrasonic sensors, and tactile sensors are some of the most common types of sensors. Through interpretation of the information collected by these sensors, robots can make informed decisions and respond to changes in their environment, thus making them highly adaptable.
2. Actuators
The actuators are some of the important parts of robotics and the actuators in a robot can be termed as the muscles of a robot, as they provide motion to the robot. They are responsible for changing electrical energy into mechanical motion to enable the robot to walk, lift, or move objects. Based on the robot’s design and function, electric motors, and hydraulic, and pneumatic devices are used.

3. Control System
The control system of different robotics parts acts as the brain of the robot, which guarantees a reliable decision-making process. It processes information from the sensors and sends commands to the actuators. This includes hardware and software that enables the robot to analyze data, make decisions, and execute tasks. Microcontrollers and embedded systems are some of the common components of a robot’s control system, allowing for real-time processing and controls.
4. Power Supply
A power source is needed for the functioning of any robot, and this power supply, which forms one of the crucial robotics components, provides the necessary energy for operating the sensors, actuators, and control system. Depending on the robot’s application, its power sources could be batteries, solar panels, or direct electrical connections. The choice of the power supply is very crucial since it determines the range, efficiency, and operational time of the robot.
5. Chassis
The chassis is the most important part of a robot, as it provides the support and housing structure for its various components. Its design determines the shape, size, and stability of the robot. Chassis designs can range from wheeled or tracked bases for mobile robots to articulated frames for robotic arms. A good chassis design will ensure that the robot navigates its environment and performs tasks effectively.

6. Software
A robot’s sensor, actuators, and its control systems work on software; it is that part of a robot that deals with the data processing, motion control, and complex tasks are executed by this part. Such algorithms are made on programming languages Python, C++, and ROS: Robot Operating System. The quality of software development is critical in achieving efficient and reliable robot performance. With AI in the building and programming of robots, it combines machine learning and neural networks to enhance a robot’s ability to learn from its environment. This fusion leads to more autonomy and adaptability, which enables robots to efficiently execute complex tasks in dynamic environments.
7. User Interface
Human-robot interaction is essentially bridged through the user interface. It gives users the option to control, monitor, and receive feedback about the performance of the robot. UIs could be as simple as buttons and switches or touch screen displays that can be accompanied by voice commands. A good interface is what makes it accessible and simple enough for operators to communicate with the robot and be able to access features..
8. Communication System
The communication system is the means through which the robot can communicate with other robots or devices. It can be achieved through wired connections, Wi-Fi, Bluetooth, or other wireless protocols. Effective communication allows robots to work collaboratively, share data, and perform tasks more efficiently in a connected environment. The advent of humanoid robots is revolutionizing communication. These robots, mimicking human gestures and expressions, make interactions more natural and engaging. Consider Sophia and Pepper, advanced AI-enabled robots that can well understand and respond to human emotions, thereby leading to a future where humans can interact seamlessly with robots.
A recent report by Interact Analysis stated that global demand for basic components in industrial robots hit a $12.1 billion threshold in 2022, indicating a 14.7 percent year-on-year growth. In this regard, the report concluded that the bulk of the production was mainly seen in collaborative and SCARA robots. The component market is said to slow down as the robot market matures and stabilizes in the coming years. The market for industrial robot components, however is likely to increase by 8.8 percent annually during the 2022 to 2027 period.

It reminded me of a robotics competition I participated in where we had to design a maze-solving robot. The most challenging part was fine-tuning the sensors to navigate accurately and integrating them with the control system. It really hit home how crucial it is for all the components like sensors, actuators, and programming, to work seamlessly together. It was a rewarding experience and deepened my appreciation for how complex and interconnected robotics truly is.
I’m curious to know when it comes to integrating sensors with actuators in a robot, what are some of the biggest challenges students face in ensuring they work together seamlessly? Is there a specific technology or approach that’s helping to improve this integration?
Thank you for sharing your curiosity!! Integrating sensors with actuators can be challenging as it requires precise coordination for real-time responses. A major hurdle is minimizing latency between sensor data and actuator actions to avoid delays in movement. Sensor fusion, where data from multiple sensors is combined, helps improve accuracy and decision-making. Additionally, advanced control algorithms ensure smoother coordination. At Moonpreneur, we focus on hands-on projects that give students the chance to experiment with these technologies and see how sensors, actuators, and control systems work together in real-world applications.
