  This conceptual paper overviews how blockchain technology is involving the
operation of multi-robot collaboration for combating COVID-19 and future
pandemics. Robots are a promising technology for providing many tasks such as
spraying, disinfection, cleaning, treating, detecting high body
temperature/mask absence, and delivering goods and medical supplies
experiencing an epidemic COVID-19. For combating COVID-19, many heterogeneous
and homogenous robots are required to perform different tasks for supporting
different purposes in the quarantine area. Controlling and decentralizing
multi-robot play a vital role in combating COVID-19 by reducing human
interaction, monitoring, delivering goods. Blockchain technology can manage
multi-robot collaboration in a decentralized fashion, improve the interaction
among them to exchange information, share representation, share goals, and
trust. We highlight the challenges and provide the tactical solutions enabled
by integrating blockchain and multi-robot collaboration to combat COVID-19
pandemic. The framework of our conceptual proposed can increase the
intelligence, decentralization, and autonomous operations of connected
multi-robot collaboration in the blockchain network. We overview blockchain
potential benefits to defining a framework of multi-robot collaboration
applications to combat COVID-19 epidemics such as monitoring and outdoor and
hospital End to End (E2E) delivery systems. Furthermore, we discuss the
challenges and opportunities of integrated blockchain, multi-robot
collaboration, and the Internet of Things (IoT) for combating COVID-19 and
future pandemics.
