'''Collective robotics''' is the study of multi-robot systems in which autonomous agents coordinate to perform tasks that exceed the capabilities of any individual robot. While overlapping with [[Swarm robotics|swarm robotics]], collective robotics is broader: it encompasses not only large homogeneous swarms governed by simple local rules but also heterogeneous teams with specialized roles, explicit communication protocols, and hierarchical coordination structures. The field asks not merely how robots can flock or forage but how they can jointly manipulate objects, assemble structures, and make collective decisions in environments where individual competence is insufficient.

The intellectual lineage of collective robotics traces through three tributaries: [[Artificial life|artificial life]], which established that collective behavior need not be centrally programmed; [[Swarm intelligence|swarm intelligence]], which provided algorithmic frameworks for decentralized optimization; and [[Distributed System|distributed systems theory]], which supplied formal models of consensus, fault tolerance, and communication complexity. The field's distinctive contribution is its insistence on '''embodiment''': collective robotics studies physical robots with mass, friction, sensing noise, and energy constraints, not abstract agents in simulation. The gap between simulated collectives and physical ones is the field's central methodological obsession.

== Core Capabilities ==

Collective robotics has demonstrated three classes of capability that individual robots cannot achieve alone:

'''[[Cooperative transport]]''': Multiple robots jointly carry objects too heavy, large, or awkward for a single agent. The challenge is not merely adding force vectors but coordinating grip points, balancing loads, and recovering from individual failure without dropping the payload. Biological inspiration comes from ants transporting prey and leafcutter ants moving plant matter; engineered systems have demonstrated cooperative transport of beams, pipes, and even small vehicles.

'''[[Self-assembly]]''': Robots autonomously connect to form functional structures — bridges over gaps, shelters in hazardous environments, or reconfigurable lattice structures that adapt to task requirements. Unlike pre-programmed formation control, self-assembly requires robots to evaluate local conditions, decide whether to connect or disconnect, and maintain structural integrity under perturbation. The canonical platform is the [[M-TRAN]] system, in which modular robots reconfigure from snake-like to wheel-like morphologies depending on terrain.

'''Collective perception and mapping''': Robots pool sensor data to build global maps or track dynamic targets that no individual can observe completely. This requires not only distributed data fusion but also consensus on what is being observed — a problem that becomes acute when sensors disagree, communication is intermittent, or the environment contains adversarial elements.

== Control Architectures ==

The control architectures of collective robotics span a spectrum from fully decentralized to explicitly hierarchical:

At the decentralized extreme are '''reactive architectures''', in which each robot responds to local sensor input without maintaining global state or explicit communication. These architectures scale well and are robust to failure, but they are limited to tasks that can be solved by local rules — path following, obstacle avoidance, simple aggregation. [[Braitenberg vehicles|Braitenberg vehicles]], though designed for single agents, illustrate the reactive paradigm: direct sensorimotor coupling without internal representation.

At the hierarchical extreme are '''market-based architectures''', in which robots bid for tasks and a central or distributed auction mechanism allocates resources. These architectures handle heterogeneity and specialization well but introduce single points of failure and communication bottlenecks.

Between these poles lie '''hybrid architectures''', which use local coordination for routine behavior and explicit negotiation for exceptional conditions. The most successful deployed systems — warehouse robots, agricultural swarms, search-and-rescue teams — use hybrids, not pure decentralization. The claim that swarm
