## 5 Basic Behaviors and Tasks in Swarm Robotics
### Collective Mapping  
Collective mapping is the dilemma of synchronizing a collection of robots and co-hesively budgeting the swarm. This formation owns a precise shape such as a line or is random like a flocking. [PERSON] and [PERSON] [133] proposed a new procedure of cooperative mapping and navigation in the undiscovered ambiance by a group of movable robots. Every robot is provided with a reached sensor of a restricted area to observe and grasp. A particular aim is attributed to every robot that must explore an unexplored area. The sensory knowledge about ambiance gathered from every robot is swapped to generate a public map of the investigated area. The authors use an objective function that, in the beginning, intends to find out every robot's aims region, a boundary investigation takesplace. The boundary is chosen by using a switching cost function that regards the feasible finding out of the aim area of an agent by else limb of the group. When an agent's aim area is within the disconnected explore subarea, the navigation function is changed to a geodesic function that guarantees the navigation to the explored region. Experiment results show that the suggested control method navigates lead the group capably to the specific aim positions.  
[PERSON] et al. [134] proposed a method for reaching collective movement in a group of robotic boats aiming at ocean surface mapping. The authors show implementation and experimental tests to authenticate the idea in a sea evaluation with 16-24 robotic boats. The method employs local neighbor communication and responds to outer knowledge calculated in a mentor's ambient features or inner knowledge. The authors formulate and prove three types of behaviors and show experimental tests from area assays performed in Catalina Harbor in California. [PERSON] et al. [135] research a swarm mapping procedure wherein the agents initially separately map the environment through random walking. After that, the authors join the agent's maps to a single one. The authors also concentrate on five variants of random walking and contrast the maps' standard that a swarm yields whenever investigating the environment using this variant. The tests indicate that it is feasible together to map the environment blending them. The authors affirm the standard's map relies on the investigation behavior of the agents. Experiments results that notwithstanding the individual maps being unfinished, it is acceptable to create a map by fusing them collaboratively. The results indicate the ballistic motion provides superior mapping outcomes for covered areas.  
[PERSON] et al. [136] suggested a collective computing system employed on a complicated task: collective mapping. This system is supported by swarm models, which offer these main qualities: robustness, scalability, and flexibility. This system enables a decentralized and distributed mapping with scalability to independents systems managing broad environments compared with present approaches. The experiments affirm the efficiency of this collaborative approach. The authors find out the topology of the network influence the functioning of the collaborative act.
