The employment of renewable forms of energy is important all over the world, not just in countries where there are concerns over the accessibility of fossil fuels. With the aim of developing and encouraging appropriate energy policies for the future, it is required to gain an understanding of professional views in all countries, as well as those with extensive fossil fuel reserves. The volume of construction work in the countries with hot and dry climates （like Middle Eastern countries） has recently been at exceptional levels, with an enormous environmental impact from construction and also from potential of future energy demands. The purpose of this paper is to evaluate the potential usage of a particular, but precious, renewable energy options: smart materials in those climates. Such exploitation could alleviate, at least in some part, the future environmental burdens. A large-scale assessment, followed by a number of in-depth interviews, has been undertaken with the aim of examining the application of smart materials in connection with sustainability and energy efficiency and assesses the optimization of proposed smart materials and their products in favor of this region. Experimental research findings are presented, and then analyzed with the purpose of determining the present capability of a significant development of smart materials in the hot and dry climatic regions. Suggestions are then provided to help the improvement of appropriate application and the wider introduction of viable smart materials in these regions.

Soft robots are featured with safe interaction, good adaptability, and strong flexibility due to their own material composition and structural peculiarities. Nowadays, they are widely used in medical services, agricultural harvesting, disaster relief and rescue, underwater exploration and other fields. This paper provides a summary of soft robotic drive modes and drive materials, and classifies soft robotic drive modes into flexible fluid drive and smart material drive according to whether smart materials are included or not, where flexible fluid drive is illustrated from the three aspects of soft body structure, material and power source. With the development of smart materials, this paper proposes the connection between smart materials and soft robots for the first time, summaries the exposition from the aspects of principle, materials and structure, and finally discusses the soft robot drive and looks forward to its future development.
