Abstract

Purpose

The objective of this work was to demonstrate a novel approach to human machine interaction that seamlessly uses teleoperation and automation in a complex environment.

Design/methodology/approach

This work leverages developments in the area of operational software Operational Software Components for Advanced Robotics (OSCAR), decision making, human‐machine interface, and motion planning. This demonstration uses a 17 degrees‐of‐freedom (DOF) dual arm robot that is equipped with modern tool changers, crash protectors, force‐torque sensors and electrical and pneumatic power at the tools. Four different end‐effector tools are also provided. These are electric grippers, electric rotary saw, electric drill, and a pneumatic spray gun. The system can be used both in teleoperation and automation mode. In teleoperation mode, the user has a choice of five different input devices. These are computer keyboard, spaceball and spacemouse, RSI manual controller and kraft force feedback controller. Automation is performed using a novel graphical user interface with 3D graphics used for previewing and verifying manipulator motion. Automation tasks that are demonstrated include automatic grasping, sawing, drilling, spray painting, point‐to‐point motion, and teaching. The controller for the dual arm system is developed using OSCAR and supports a variety of decision‐making algorithms and obstacle avoidance. The integration of this controller with the input devices and human machine interface is done using a novel protocol that is based on Extensible Markup Language (XML) for maximum reuse and distributed integration. This protocol is further based on a well‐defined and scalable XML schema that can be easily extended as controller functionality is changed and/or additional input devices are added.

Findings

It is necessary to combine automation with teleoperation to reduce worker fatigue and also provide higher value robotic functions. This is possible as most remote tasks can be broken down into structured and unstructured components. On the integration front, we see XML‐based integration providing a loosely coupled system that can make interoperability between various robot systems possible. For end‐effector tooling, it is better to have special purpose tools that can be switched out versus the use of a general purpose tool such as a robotic hand.

Research limitations/implications

This research was done in a laboratory environment, and as such, its application in the field will require partnering with a commercial entity. Force‐feedback on manual controllers during teleoperation was not very effective. In fact, providing visual queues to the operator about the forces were a better guide to the operator.

Practical implications

The software for this work provides obstacle avoidance capability. The obstacle avoidance is based on a known world model that is derived from a CAD environment. In reality, this model will have to be sensed in real‐time, and decoded into a geometric model. Significant work in this area needs to be done.

Originality/value

The software developed for this work was based on the OSCAR software framework. This is a unique framework that at its core uses performance criteria to control the behavior of the robot during teleoperation and automation. The value of this work is that it shows as completely feasible the control of a 17 DOF dual arm system using the latest integration technologies (such as XML), integrated simulation, multiple tools and multiple input devices. It also shows that all these choices can be provided to an operator through a single user interface.

Abstract

Purpose

Governments in both developing and developed economies play an active role in labor markets in the form of providing both formal public sector jobs and employment through public workfare programs. The authors refer to this as employment targeting. The purpose of the paper is to consider different labor market effects of employment targeting in a stylized model of a developing economy. In the context of a simple search and matching friction model, the authors show that the propensity for the public sector to target more employment can increase the unemployment rate in the economy and lead to an increase in the size of the informal sector.

Design/methodology/approach

The model is an application of a search and matching model of labor market frictions, where agents have heterogeneous abilities. The authors introduce a public sector alongside the private sector in the economy. Wage in the private sector is determined through Nash bargaining, whereas the public sector wage is exogenously fixed. In this setup, the public sector hiring rate influences private sector job creation and hence the overall employment rate of the economy. As an extension, the authors model the informal sector coupled with the other two sectors. This resembles developing economies. Then, the authors check the overall labor market effects of employment targeting through public sector intervention.

Findings

In the context of a simple search and matching friction model with heterogeneous agents, the authors show that the propensity for the public sector to target more employment can increase the unemployment rate in the economy and lead to an increase in the size of the informal sector. Employment targeting can, therefore, have perverse effects on labor market outcomes. The authors also find that it is possible that the private sector wage falls as a result of an increase in the public sector hiring rate, which leads to more job creation in the private sector.

Originality/value

What is less understood in the literature is the impact of employment targeting on the size of the informal sector in developing economies. The authors fill this gap and show that public sector intervention can have perverse effects on overall job creation and the size of the informal sector. Moreover, a decrease in the private sector wage due to a rise in public sector hiring reverses the consensus findings in the search and matching literature which show that an increase in public sector employment disincentivizes private sector vacancy postings.

Abstract

Purpose

This study explores consumers' intentions to utilize online food delivery services (OFDS) in a shared economy beyond the COVID-19 pandemic, employing the protection motivation theory (PMT) as the underlying framework.

Design/methodology/approach

Utilizing a random sampling technique, a quantitative approach was employed to gather responses from 347 Australian consumers. The proposed model was tested through covariance-based structural equation modelling.

Findings

The findings of this study demonstrate significant positive relationships between restaurant credibility, food quality, e-service quality, price, online food delivery applications, consumer e-satisfaction and e-loyalty. It reveals that consumers satisfied with OFDS may continue exhibiting e-loyalty intentions in a shared economy beyond COVID-19. The relationship between consumer e-satisfaction and e-loyalty intention is moderated by consumer-perceived COVID-19 risk.

Practical implications

This study offers practical implications for online food delivery providers, restaurants, regulators, application developers and policymakers. These implications aim to enhance the e-service quality, price value, usefulness and security of OFDS, along with strategies to improve the online food delivery application.

Originality/value

This study contributes to the existing body of knowledge by examining a unique selection of antecedents, including the OFDS app, to determine consumer e-satisfaction and e-loyalty in the context of a shared economy beyond COVID-19. The utilization of the OFDS app as a second-order construct adds a meaningful contribution to the OFDS literature. Furthermore, this study investigates and contributes to the limited understanding of the moderation effect of consumer-perceived COVID-19 risk on consumer e-satisfaction and their intended continued use of OFDS.

Case overview

Niyogi Books had positioned itself as an independent publishing house with a focus on the niche area of trade books. Due to the internet, digitalization and globalization the dynamics of the book publishing industry had changed considerably, and the company needed to think and reflect on its current position and future strategy. Niyogi Books had added new products and new markets along with other innovations to succeed in the business of publishing. But the way ahead for Niyogi Books was to innovate in light of fast-paced technological advancement. The company needed to balance the digitization of content as well as retailing with its existing print strategy. A related issue is the need to plan an innovative and cost-effective communication strategy to boost sales.
