What is an Autonomous Robot?
The use of the term ‘autonomous robot’ has recently become quite popular in the discourse on technology and robotics. But what does it mean in fact? Such robots form a new class of robots with a complete autonomous control system, and they hold great potential in many applications ranging from manufacturing to health care. In this blog, we will define what autonomous robots are, how they function, the various uses of autonomous robots, the advantages, and disadvantages of using them.
Understanding Autonomous Robots
An autonomous robot is an un-tethered device that is able to work and reason independently with out any human control. This is different from the conventional robots that are controlled either by a human being or through a set of programs, the autonomous robots are equipped with sensors, algorithms and artificial intelligence to enable them to make decisions when they are in operation.
This makes them to work effectively and with a lot of freedom especially in dynamic and complex environments.
Key Characteristics
Sensors and Perception:
Self-governing vehicles use a number of sensors including cameras, LIDAR and radar to identify the environment around them. These sensors obtain information on the surroundings thus enabling the robot to identify objects, avoid obstacles and even understand the arrangement of the objects around it.
Processing and Decision-Making:
After collecting the data the microprocessor of the robot processes this data with the help of sophisticated algorithms and artificial intelligence. This processing helps the robot to make decisions and determine the actions that it can take in a given environment and with the tasks it has set.
Actuation and Execution:
The immediate output from the decision making process of the robot is its actuators which include motors, servos among others to carry out activities or movements within its environment. The Execution phase is the final stage whereby the robots decisions made are implemented to physical actions such as motion, grasping among other actions.
Types of Autonomous Robots
There are several categories of the autonomous robots depending on their operations and uses. Here are some common types:
Mobile Robots:
These are robots that have been fabricated to have the ability to move from one place to another and get through almost any terrain. Some of the application areas are self-driven cars, drones, or robotic cleaners such as Roomba and others. Mobile robots contain navigation systems which assist them in moving from one point to another free from obstacles.
Manipulative Robots:
These robots are intended to operate with objects and execute operations that involve handling of objects. Some of the examples include industrial robots that are used in manufacturing, robotic arms that are used in manufacturing lines and surgical robots that are used in surgeries.
Social Robots:
Social robots are robots that are meant to be used in the company of people as well as to help them in some way. Some examples include; personal assistant robots, elder care robots, and educational robots in schools.
How Autonomous Robots Work
In order to gain an insight into how self-governing robots work, it is necessary to look at the basic elements and mechanisms of the latter.
1. Sensors and Data Acquisition
Sensors are important in self-organized robots since they enable the robot to get information of the surrounding environment. Different types of sensors include:
Cameras: Capture pictures, and to perform image detection and understanding.
LIDAR (Light Detection and Ranging): Identifies distance by utilizing laser beams to build an accurate model of the surroundings in 3D form.
Radar: Employing radio waves to identify objects and their location as well as their motion.
Ultrasonic Sensors: A method of measuring distance which employs sound waves and is frequently employed in obstacle avoidance.
2. Data Processing and AI
After the data is acquired by the sensors then it has to be analyzed so that decisions can be made. This involves several steps:
Data Fusion: Fusion of information coming from several sensors in order to get the overall picture of the situation.
Localization: Estimating the robot’s position and orientation in the world it is operating in.
Mapping: Making the maps of the environment or updating them with the help of sensor data.
Path Planning: Determining the best course of action in order to reach the given goals of the robot while navigating around obstacles.
It is very important in this process and this is where artificial intelligence comes in. The machine learning algorithms and the neural networks enable robots to learn and categorise from the given input and also make future predictions.
3. Control Systems
We use control systems to implement the decisions that the robot’s AI has made into physical actions. This involves:
Motion Planning: How the robot should navigate to achieve its goals, therefore, becoming an important factor to be considered.
Actuation: Control of the robot’s actions and movement through use of motors and servos.
Feedback Loops: Observing the behavior of the robot and changing some parameters if it is necessary.
