How do robots avoid collisions during multi-robot coordination?

Asked on Nov 02, 2025

Answer

Robots avoid collisions during multi-robot coordination by employing techniques such as decentralized control, communication protocols, and motion-planning algorithms that ensure safe navigation and coordination. These methods often involve real-time sensor data processing, path planning, and dynamic obstacle avoidance strategies to maintain safe distances between robots.

Example Concept: Collision avoidance in multi-robot systems typically uses algorithms like the Reciprocal Velocity Obstacle (RVO) or Optimal Reciprocal Collision Avoidance (ORCA). These algorithms calculate safe trajectories by considering the velocities and positions of nearby robots, allowing each robot to adjust its path dynamically to prevent collisions. This decentralized approach enables each robot to make independent decisions while maintaining overall system coordination.

Additional Comment:

Ensure each robot is equipped with sensors like LiDAR or cameras for real-time environment perception.
Implement communication protocols to share position and velocity data among robots.
Test the coordination strategy in simulation environments before real-world deployment.
Consider using ROS frameworks for integrating multi-robot coordination algorithms.
