A swarm robot is a small autonomous robot that’s part of a larger group that works together to perform a task. Swarm robots communicate using signals to coordinate actions to achieve the same goal.

The concept behind swarm robotics is based on the collective behavior of ants, bees, termites, and other social insects. Because of their size, swarm robots have various applications, including environmental monitoring, search and rescue, and disaster relief.

Imagine a swarm of robots helping farmers perform mundane tasks, such as weeding without damaging plants. That is just one example of the potential uses of this technology. We’ll talk more about swarm robots below.

How Did Swarm Robots Originate?

The term “swarm robotics” was coined in 1988 by Gerardo Beni and Jing Wang, two professors at the University of California. Inspired by the collaborative behavior of social insects, they proposed that swarm robots could be used to perform complicated tasks that would be difficult for individual robots to perform.

Several experts explored the concept, but it wasn’t until 2000 that a major research project on swarm robotics called “SwarmBots” was launched.

In 2014, the Harvard University developed a swarm of 1,024 robots called “Kilobots.” Each robot was cylindrical and measured 3 centimeters. They were given a picture of a shape and worked together for 12 hours to form it.

How Does a Swarm Robot Communicate?

A swarm robot can communicate with others using various methods, such as:

  • Artificial pheromones: This form of communication was inspired by the pheromones that social insects use. Swarm robots can be designed to release artificial pheromones that other robots can detect.
  • Bluetooth: This wireless technology enables short-range communication between swarm robots.
  • Wireless local area network (WLAN): A swarm robot can transmit data to another robot using a WLAN.
  • Stigmergy: Smart robots can be designed to leave chemical traces that others can interpret and track.

The communication method depends on the specific use of the robots and the environment they will operate in. Wireless communication means, such as Bluetooth and WLAN, may not be effective in areas with lots of noise and barriers. 

What Are the Benefits of Swarm Robotics?

Swarm robotics is a promising technology with several applications that can help save lives. Below are some of the advantages of developing this field.

  • Efficiency: Swarm robots can work together to complete tasks better than individual robots because of collaboration.
  • Adaptability: These robots can be versatile since they can be reprogrammed to perform other tasks. For instance, a swarm of robots designed for search and rescue could be reprogrammed to help with disaster relief.
  • Resilience: If one or more robots fail, the swarm can still complete the task since they can communicate and share information.
  • Cost-effective: Swarm robots can be inexpensive to build and operate, making them accessible to many organizations. Their adaptability also helps entities save money.

What Are the Uses of Swarm Robots?

While the experiment on Kilobots was simple, its potential was evident. A swarm robot can do more than form a shape. Below are some of their applications.

  • Search and rescue operations: Swarm robots can help find survivors of natural disasters like earthquakes and floods. They can quickly enter small spaces and cover large areas, making them crucial in life-and-death situations.
  • Environmental monitoring: The technology can monitor coral reefs for signs of damage, measure pollution levels in rivers and lakes, and track the spread of invasive species. These robots can go to areas that might be dangerous for humans.
  • Manufacturing: The technology can effectively perform tasks, such as assembly, inspection, and quality control. For example, swarm robots can assemble electronic devices and inspect products for defects.
  • Agriculture: Swarm robots can harvest crops quickly and efficiently, control pests without using pesticides, and weed crops without damaging plants.

These are some potential uses of swarm robotics in various fields.
