Abstract
Robotics is a growing industry with applications in numerous markets, including retail, transportation, manufacturing, and even as personal assistants. Consumers have evolved to expect more from the buying experience, and retailers are looking at technology to keep consumers engaged. There are currently many interesting initiatives that explore how robots can be used in retail. In today's highly competitive business climate, being able to attract, serve, and satisfy more customers is a key to success. A happy customer is more likely to be a loyal one, who comes back and often to the store. It is our belief that smart robots will play a significant role in physical retail in the future. One successful example is wGO, a robotic shopping assistant developed by Follow-Inspiration. The wGO is an autonomous and self-driven shopping cart, designed to follow people with reduced mobility in commercial environments. With the Retail Robot, the user can control the shopping cart without the need to push it. This brings numerous advantages and a higher level of comfort since the user does not need to worry about carrying the groceries or pushing the shopping cart. The wGO operates under a vision-guided approach based on user-following with no need for any external device. Its integrated architecture of control, navigation, perception, planning, and awareness is designed to enable the robot to successfully perform personal assistance while the user is shopping. This paper presents the wGOs functionalities and requirements to enable the robot to successfully perform personal assistance while the user is shopping in a safe way. It also presents the details about the robot's behaviour, hardware and software technical characteristics. Experiments conducted in real scenarios were very encouraging and a high user satisfaction was observed. Based on these results, some conclusions and guidelines towards the future full deployment of the wGO in commercial environments are drawn.

Abstract
The success of the Emergency Plan depends on the ability of its occupants to respond. For this reason, it is fundamental to develop an appropriate training strategy for each organization. This pilot study aimed to understand the influence of specific training program on the emergency response. This study included a total of twenty-two workers of a company. The workers were divided into three emergency response teams with four elements and one another group with ten elements. The emergency response team had specific training actions with theoretical and practical contents. Finally, all workers participated in an activity called emergency scenarios, where a moment of brainstorming was provided for the solve each scenario. The classifications obtained in different assessments moments (M1: after training and M2: after three weeks of training) revealed that knowledge had been acquired by participants. Additionally, it was verified that teams, with specific training, presented better results in their specific scenario. The emergency response training may have better results if it enhances teamwork and the involvement of all stakeholders. © Springer Nature Switzerland AG 2019.
