Self-organization in aggregating robot swarms: A DW-KNN topological approach

Abstract: In certain swarm applications, where the inter-agent distance is not the only factor in the collective behaviours of the swarm, additional properties such as density could have a crucial effect. In this paper, we propose applying a Distance-Weighted K-Nearest Neighbouring (DW-KNN) topology to the behaviour of robot swarms performing self-organized aggregation, in combination with a virtual physics approach to keep the robots together. A distance-weighted function based on a Smoothed Particle Hydrodynamic (SPH)… Show more

“…k NN is one of the simplest non-parametric classification methods with an easily interpretable output, low calculation times, and high predictive power. Furthermore, it is widely used in classification and regression problems for real applications [ 23 , 24 , 25 , 26 ]. The algorithm is based on the predictions for a new instance ( x ) by searching through the entire training set for the most similar instances of k (the neighbors) and summarizing the output variable for those k instances.…”

“…With the VVC model, we specically used the RAB (range and bearing) communication device for inter-robots communications and two-wheeled actuators to independently control the forward speed of the robots right and left wheels. The total virtual viscoelastic force F i vvc exerted on a robot i is obtained using Equation (1). Then basing on that force, the desired forward speeds v ri and v l i of the right and the left wheels of the robot is given in Equation 2.…”

“…S WARM intelligence has been remarkably observed in many biological organisms such as social insects and order living animals [1]. With swarm intelligence, complex swarming behaviours can emerge from simple interactions within individuals of a swarm in addition to their interaction with their environment [2].…”

“…The fourth, selected technique was a k-Nearest-Neighbours (kNN) clustering algorithm. K-NN is one of the simplest non-parametric classification methods with an easily interpretable output, low calculation times, and high predictive power (Aziz et al 2018;Khaldi et al 2018;Beruvides et al 2017;Penedo et al 2012). The setting parameters used was a Euclidean distance and the number of neighbours equal to 5.…”
