Ub Swarm: Hardware Implementation of Heterogeneous Swarm Robot With Fault Detection and Power Management

Abstract

In this work we present the hardware architecture of a mobile heterogeneous robot swarm, designed and implemented at the Interdisciplinary Robotics, Intelligent Sensing and Control (RISC) Laboratory, University of Bridgeport. Most of the recent advances in swarm robotics have mainly focused on homogeneous robot swarms and their applications. Developing and coordinating a multi-agent robot system with heterogeneity and a larger behavioral repertoire is a great challenge. To give swarm hardware heterogeneity we have equipped each swarm robot with different set of sensors, actuators, control and communication units, power supply, and an interconnection mechanism. This paper discusses the hardware heterogeneity of the robotic swarm and its challenges. Another issue addressed in paper is the active power management of the robotic agents. The power consumption of each robot in the UB robot swarm is calculated and the power management technique is also explained in this paper. We applied this heterogeneous robot swarm to perform three sample tasks – Mapping task, human rescue task and wall painting task.

Past, Present, and Future of Swarm Robotics

“…The focus was to build heterogeneous swarms. The UB-swarm project [180] also built a swarm of heterogeneous robots. Thus, in our opinion we suggest some software requirements include the implementation of:…”

Information Support of the Remote Nitrogen Monitoring System in Agricultural Crops

“…The use of a dedicated sensor is shown in [7][8][9]. These decisions are difficult to implement for RP because of the lack of natural optical templates in fields during low flying, and a large amount of power supply for the test sites lighting.…”

Development of an Intelligent Robotic System for Plasma Processing of Industrial Products with Complex Shape

“…Flow chart of the process of microplasma spraying by an intelligent robotic system Thus, the trajectory plan must be generated for the thermal spraying process without any initial knowledge of the products shape or orientation. The closest to the main ideas of this study are the different algorithms developed by Kondratenko et al [16,17], Tkachenko et al [18] and Patil et al [19] for the operation of an intelligent robot in an environment with uncertainty. In this case, the trajectory is formed by the robot control system based on information about the current state of the external environment, that is, according to the 3D model of the processed surface reconstructed by the robot, which is a point cloud (coordinates of the object surface).…”
