TL;DR

This paper proposes a nature-inspired collaborative robotics framework using Ant Colony Optimization (ACO) and Particle Swarm Optimization (PSO) to enable mobile robots to self-organize, self-assemble, and dynamically reconfigure into adaptive structures for enhanced task performance. The approach leverages swarm intelligence to coordinate collective behavior in response to environmental changes, demonstrating improved reliability and problem-solving capability over single robots.

ABSTRACT

This paper introduces collaborating robots which provide the possibility of enhanced task performance, high reliability and decreased. Collaborating-bots are a collection of mobile robots able to self-assemble and to self-organize in order to solve problems that cannot be solved by a single robot. These robots combine the power of swarm intelligence with the flexibility of self-reconfiguration as aggregate Collaborating-bots can dynamically change their structure to match environmental variations. Collaborating robots are more than just networks of independent agents, they are potentially reconfigurable networks of communicating agents capable of coordinated sensing and interaction with the environment. Robots are going to be an important part of the future. Collaborating robots are limited in individual capability, but robots deployed in large numbers can represent a strong force similar to a colony of ants or swarm of bees. We present a mechanism for collaborating robots based on swarm intelligence such as Ant colony optimization and Particle swarm Optimization

Motivation & Objective

• To develop a collaborative robotics system that enhances task performance through collective intelligence.
• To enable mobile robots to self-assemble and self-organize into dynamic, reconfigurable structures.
• To apply nature-inspired meta-heuristics like ACO and PSO to coordinate robot behavior in uncertain or changing environments.
• To improve system reliability and adaptability by leveraging swarm intelligence principles.
• To demonstrate that collective robot systems can outperform individual robots in complex problem-solving tasks.

Proposed method

• The framework uses Ant Colony Optimization (ACO) to guide robot movement and task allocation based on pheromone-like signals.
• Particle Swarm Optimization (PSO) is employed to optimize the collective behavior and spatial configuration of robots.
• Robots communicate locally and adjust their behavior based on environmental feedback and shared information.
• Self-organization emerges from decentralized decision-making, allowing dynamic reconfiguration in response to environmental changes.
• The system models robot collaboration as a meta-heuristic optimization problem, where the goal is to minimize task completion time and maximize robustness.
• The approach treats robot aggregation as a dynamic optimization process, with ACO and PSO guiding structural formation and task coordination.
