COVID-19's impact on mobile robotics growth

The COVID-19 pandemic is creating the opportunity for mobile robotsto be used for various markets and could lead to a reassessment of supply chains in the future.

Gregory Hale

           Coronavirus has highlighted use cases for mobile robotics to successfully disinfect, monitor, look over, handle, and deliver materiais to the point where the market will grow to $23 billion by 2021, new research showed.

“Crises shift perceptions on what is possible regarding investment and transformative action on the part of both private and government actors,” said Rian Whitton, sênior analyst at tech market advisory firm, ABI Research. “By the time the COVID-19 pandemic has passed, robots will be mainstreamed across a range of applications and markets.” 

Mobile robots on display

 The virus has been a good opportunity for companies to display robots for public applications.

One of the more popular applications has been deploying mobile unmanned platforms with Uitravioiet (UV) light to disinfect facilities. Danish company UVD Robots is reaping the benefits of this opportunity and is scaling up deployments of robots to disinfect hospitais.

U.S.-based Germ Falcon is offering a similar UV disinfection solution for aircraft, while Chinese TMiRob is deploying disinfection robots in Wuhan.

“Automating disinfection is a key part of maintaining health and safety and could be one of the major bright spots in the response to COVID-19,” Whitton said.

Drones have also been deployed to enforce curfews and surveil areas for security purposes. 

Short-and long-term opportunities 

This represents a big opportunity for aerospace and drone companies to increase sales to government agencies. ABI Research expects the small drone delivery market to reach $414 million by 2021 and $10.4 billion by 2030.

In the short term, to enforce quarantine mandates, governments will need to increase their security apparatuses, as well as the productivity of their medicai agencies. Robots will be key to achieving that through disinfection, monitoring, and surveillance. Furthermore, the shutting down of households and even ships represents a chance for robot delivery companies (for both land and air) to display their worth. The drone delivery market could take its experience with transporting supplies in the developing world and scale up their operations in the most affected countries.

Long-term, COVID-19 is leading to a significant reassessment of the global manufacturing supply Chain. America’s dependence on Chinese imports for basic equipment and medicines is becoming a contentious issue, and government representatives are already interpreting the crisis as a chance to revitalize the campaign to bring more manufacturing capacity to the domestic market. If this translates into more significant measures by governments to diversify or bringing back the manufacturing of key goods, this could bode very well for the robotics industry, as such changes would require big increases in CAPEX and productivity improvements within developed countries.

COVID-19 represents a disaster for robotics vendors building Solutions for developed markets in manufacturing, industry, and the supply chain. But for vendors targeting markets closerto government, such as health, security, and defense, it represents a big opportunity.

Whitton said, “Industrial players develop customized Solutions for non-manufacturíng use cases or look to build comprehensive Solutions for enabling a scale-up in medicai supply manufacturing. For mobile robotics vendors and software companies targeting more nascent markets, this represents a big chance to highlight the importance of robotics for dealing with national emergencies, as well as mitigating the economic shock.”

Mathematical Modeling of Epidemie Diseases; A Case Study of the COVID-19 Coronavirus

Reza Sameni

Abstract—The outbreak of the Coronavirus COVID-19 has taken the lives of several thousands worldwide and lockedout many countries and regions, with yet unpredictable global consequences. In this research we study the epidemic patterns of this virus, from a mathematical modeling perspective. The study is based on an extension of the well-known susceptible-infectedrecovered (SIR) family of compartmental models. It is shown how social measures such as distancing, regional lockdowns, quarantine and global public health vigilance influence the model parameters, which can eventually change the mortality rates and active contaminated cases over time, in the real world. As with all mathematical models, the predictive ability of the model is limited by the accuracy of the available data and to the so-called levei of abstraction used for modeling the problem. In order to provide the broader audience of researchers a better understanding of spreading patterns of epidemic diseases, a short introduction on biological systems modeling is also presented and the Matlab source codes for the simulations are provided online. 

I. Introduction 

Since the outbreak of the Coronavirus COVID-19 in January 2020, the virus has affected most countries and taken the lives of several thousands of people worldwide. By March 2020, the World Health Organization (WHO) declared the situation a pandemic, the first of its kind in our generation. To date, many countries and regions have been locked-down and applied strict social distancing measures to stop the virus propagation. From a strategic and healthcare management perspective, the propagation pattern of the disease and the prediction of its spread over time is of great importance to save lives and to minimize the social and economic consequences of the disease. Within the scientific community, the problem of interest has been studied in various communities including mathematical epidemiology, biological systems modeling, signal Processing and control engineering.

In this study, epidemic outbreaks are studied from an interdisciplinary perspective, by using an extension of the susceptibleexposed-infected-recovered (SEIR) model, which is a mathematical compartmental model based on the average behavior of a population under study. The objective is to provide researchers a better understanding of the significance of mathematical modeling for epidemic diseases. It is shown by simulation how social measures such as distancing, regional lockdowns and public health vigilance can influence the model parameters, which in turn change the mortality rates and active contaminated cases over time.

It should be highlighted that mathematical models applied to real-world systems (social, biological, economical, etc.) are only valid under their assumptions and hypothesis. Therefore, this research—and similar ones—that address epidemic patterns do not convey direct clinicai information and dangers for the public, but they should rather be used by healthcare strategists for better planning and decision making. Hence, the study of this work is only recommended for researchers familiar with the strength points and limitations of mathematical modeling of biological systems. The Matlab codes required for reproducing the results of this research are also online available in the Git repository of the project. In Section II, a brief introduction to mathematical modeling of biological systems is presented to highlight the scope of the present study and to open perspectives for the interested researchers, who may be less familiar with the context. The proposed model for the outspread of the Coronavirus is presented in Section III. The article is concluded with some general remarks and future perspectives.

Abstract 

In this paper we develop a mathematical model for the spread of the coronavirus disease 2019 (COVID-19). It is a new 0-SEIHRD model (not a SIR, SEIR or other general purpose model), which takes into account the known special characteristics of this disease, as the existence of infectious undetected cases and the different sanitary and infectiousness conditions of hospitalized people. In particular, it includes a novel approach that considers the fraction 0 of detected cases over the real total infected cases, which allows to study the importance of this ratio on the impact of COVID-19. The model is also able to estimate the needs of beds in hospitais. It is complex enough to capture the most important effects, but also simple enough to allow an affordable identification of its parameters, using the data that authorities report on this pandemic.

We study the particular case of China (including Chinese Mainland, Macao, Hong-Kong and Taiwan, as done by the World Health Organization in its reports on COVID-19), and use its reported data to identify the model parameters, which can be of interest for estimating the spread of COVID-19 in other countries. We show a good agreement between the reported data and the estimations given by our model. We also study the behavior of the outputs returned by our model when considering incomplete reported data (by truncating them at some dates before and after the peak of daily reported cases). By comparing those results, we can estimate the error produced by the model when identifying the parameters at early stages of the pandemic. Finally, taking into account the advantages of the novelties introduced by our model, we study different scenarios to show how different values of the percentage of detected cases would have changed the global magnitude of COVID-19 in China, which can be of interest for policy makers.

1. Introduction 

Modeling and simulation are important decision tools that can be useful to control human and animal diseases. However, since each disease exhibits its own particular biological characteristics, the models need to be adapted to each specific case in orderto be able to tackle real situations.

Coronavirus disease 2019 (COVID-19) is an infectious disease emerging in China in December 2019 that has rapidly spread around China and many other countries. On 11 February 2020, the World Health Organization (WHO) renamed the epidemic disease caused by 2019-nCoV as strain severe acute respiratory syndrome coronavirus 2 (SARSCoV-2).

This is a new virus and a completely new situation. On 30 January 2020, WHO declared it to be a Public Health Emergency of International Concern. As of 11 March 2020, the disease was confirmed in more than 118,000 cases reported globally in 114 18 countries, more than 90 percent of cases are in just four countries (two of those China and the Republic of Korea - have significantly declining epidemics) and WHO declared it to be a pandemic, the first one caused by a coronavirus. On 1 April 2020 there are 872,481 and 43,275 official reported cases and deaths, respectively, and there is no vaccine specifically designed for this virus, with proven effectiveness.

There are some mathematical models in the literature that try to describe the dynamics of the evolution of COVID-19. (...) Other works, propose SEIR type models with little variations and some of them incorporate stochastic components. COVID-19 is a disease caused by a new virus, which is generating a worldwide emergency situation and needs a model taking into account its known specific characteristics.
