Advanced technologies and sustainable development goals (SDGs) (1): Smart city

Author: Caijun Zhao

Urbanization is one of the major trends around the world. The population in urban areas has been skyrocketing, which challenges urban living conditions and the environment. This could be due to the shortage of urban services for many people and air and water pollution. Good planning and management are the keys to ensuring the well-being of the population living in the cities. A smart city with a more efficient, sustainable, and livable environment becomes the goal for future cities. Robotics, digitalization, and automation play a significant role in achieving this goal. 

With the expansion of urbanized areas and the increase of urban problems, smart cities and intelligent buildings have been one of the hottest research topics, which covers a wide range of intelligent traffic and transportation, smart energy storage and usage, emergency management systems, and also deals with the issues in building comfort and energy saving, building safety control system and so on. 

The urban environment is becoming more and more complex. Meanwhile, the demand for environment and security is increasing. A robot presented in the paper of Yang et al. (2019) is designed to monitor the building environment and alert people by voice. With its small size and flexible movement, the robot enables the monitoring task in narrow and dangerous places. It is possible to control the robot through the mobile phone, providing users much more potential and convenience. Receiving an early warning is not enough to guarantee the safety of users in complex environments. An accurate navigation and integrated information system are needed to realize indoor positioning. As we have all experienced, navigation accuracy is poor in indoor environments, such as markets and museums. This is because the GPS signal is unstable indoors. Li and Wang (2019) conducted their research on improving accuracy in indoor navigation technology, which has enormous potential to improve the efficiency of resource utilization of large public buildings and guarantee safety and convenience for the public. In addition, many technological advances in reducing noise and establishing control models of temperature and humidity environments in smart buildings also significantly improve comfort and energy efficiency simultaneously.
