A bio-inspired mechanism to optimize information foraging in modular robotics is presented. In this context, information exchange between robotic modules are performed through intercommunication of neighbouring robotic modules with limited hardware resources. Inspired from real ant colony research, we propose virtual pheromone as a metric for parameters selection to improve communication quality in modular robotic systems. Experiment results on real robotic platforms illustrate properties of proposed method.

Abstract In modular robotics, complex structures can be formed from basic modules to solve tasks which would be difficult for a single robot. The development of techniques for adaptation and evolution of multi-robot organisms is the subject of Symbrion project Levi and Kernbach (2010). In the project, the bio-inspired evolutionary algorithms are massively simulated prior to run them on a real hardware. It is crucial to evolve behaviors of the robots in a simulation, that is close to a real world. Hence, accurate and efficient representation of an environment in the simulation is needed. The robots learn simple motion primitives or complex movement patterns during many runs of the evolution. The learned skills are then used during experiments with a real hardware. In this paper, we present methods for building 3D model of a real arena using a laser rangefinder. The resulting 3D models consist of triangles. They can be constructed in various level of details using state-of-the-art methods for 3D reconstruction. We will show, how the size of the models influences the speed of the simulation.

The area of cognitive or intelligent robotics is moving from the single robot control and behavior problem to that of controlling multiple robots operating together and even collaborating in dynamic and unstructured environments. This paper introduces the topic and provides a general overview of the current state of the field of modular and multi robotics taking both of these subareas as different representations of the same problem: how to coordinate multiple elements in order to perform useful tasks. The review shows where Hybrid Intelligent Systems could provide key contributions to the advancement of the field.

As the task complexity that robots can handle increases, the importance of coordination among multiple robots to accomplish a task has grown significantly. Existing research has primarily focused on developing a modular network topology, or a communication protocol solely focused on data communication but largely ignoring load-balancing optimizations. We discuss the existing modular robotic architectures, compare them in data and load sharing and propose a new load balancing protocol. Our load balancing system is based on having modular robotic clusters that work together by sharing resources through Kubernetes. This system improves reliability through information sharing, shared hardware resources among the robots, and scalability, allowing the architecture to expand based on need.

In this paper a hardware and software architecture based on a modular approach for a reconfigurable mobile robot is developed with intended use as remote experiment. A Field Programmable Gate Array (FPGA) was chosen as control unit for the robot and allows the implementation of custom hardware and software by the user. FPGA configurations are downloaded to the robot using a selectable wireless interface. Users can take control of all elementary robot hardware, and an on-system recovery mechanism is included to ensure a fallback to a golden image in case of errors in downloaded bit streams.

The TETROBOT is an actuated robotic structure which mag! be reassembled into many different configurations while still being controlled by the same hardware and software architecture. The TETROBOT system addresses the needs of application domains, such as space, undersea, mining, and construction, where adaptation to unstructured and changing environments and custom design for rapid implementation are required.

Today's use of large-scale industrial robots is enabling extraordinary achievement on the assembly line, but these robots remain isolated from the humans on the factory floor because they are very powerful, and thus dangerous to be around. In contrast, the soft robotics research community has proposed soft robots that are safe for human environments. The current state of the art enables the creation of small-scale soft robotic devices. In this article we address the gap between small-scale soft robots and the need for human-sized safe robots by introducing a new soft robotic module and multiple human-scale robot configurations based on this module. We tackle large-scale soft robots by presenting a modular and reconfigurable soft robotic platform that can be used to build fully functional and untethered meter-scale soft robots. These findings indicate that a new wave of human-scale soft robots can be an alternative to classic rigid-bodied robots in tasks and environments where humans and machines can work side by side with capabilities that include, but are not limited to, autonomous legged locomotion and grasping.

This paper introduces a reconfigurable underwater robot system, RS-ModCubes, which allows scalable multi-robot configurations. An RS-ModCubes system comprises multiple ModCube modules, that can travel underwater with 6 DoFs and assemble with each other into a larger structure with onboard electromagnets. This system is designed to explore the feasibility of modularity and reconfigurability in underwater robotics, eliminating the need to customize mechanical designs for a specific task. We develop a modeling framework for reconfigurable robot systems, incorporating hydrodynamic effects via Monte Carlo approximation. A model-based feedforward Proportional Derivative (PD) controller serves as the baseline for control. Inspired by dexterous manipulation, we evaluated the robot's maximum task wrench space and power efficiency, compared against four commercial underwater robots. RS-ModCubes is validated via both real-world experiments and simulations, including individual and multi-module trajectory tracking and hovering docking.
