Aerial manipulation has direct application prospects in environment, construction, forestry, agriculture, search, and rescue. It can be used to pick and place objects and hence can be used for transportation of goods. Aerial manipulation can be used to perform operations in environments inaccessible or unsafe for human workers. This paper is a survey of recent research in aerial manipulation. The aerial manipulation research has diverse aspects, which include the designing of aerial manipulation platforms, manipulators, grippers, the control of aerial platform and manipulators, the interaction of aerial manipulator with the environment, through forces and torque. In particular, the review paper presents the survey of the airborne platforms that can be used for aerial manipulation including the new aerial platforms with aerial manipulation capability. We also classified the aerial grippers and aerial manipulators based on their designs and characteristics. The recent contributions regarding the control of the aerial manipulator platform is also discussed. The environment interaction of aerial manipulators is also surveyed which includes, different strategies used for end-effectors interaction with the environment, application of force, application of torque and visual servoing. A recent and growing interest of researchers about the multi-UAV collaborative aerial manipulation was also noticed and hence different strategies for collaborative aerial manipulation are also surveyed, discussed and critically analyzed. Some key challenges regarding outdoor aerial manipulation and energy constraints in aerial manipulation are also discussed.

The oil and gas (O&G) industry has been plagued by numerous green factors that have adversely affected supply chain management practices in recent years. This study aims to examine the impact of green human resource (GHR) competency mechanisms to strengthen the relationship between green supply chain management (GSCM) practices and environmental performance (EP). Using the proposed model, the present study developed a quantitative method for obtaining data from listed O&G companies in the UAE between December 2018 and May 2019. A total of 254 questionnaires were used for the analysis. There was a significant moderating effect between EP and GSCM, with GHR competency mechanisms decreasing the occurrence of negative environmental impacts associated with O&G operations. The findings will enable HR managers to align green skills with EP in UAE petroleum companies.
