With the need to accomplish more complicated work by robots, increasing attention has been paid to cooperative assistive robotics systems and technologies over the past decades. The proposed work on sensing, control and optimization of cooperative assistive robotic systems addresses one of the recognized major challenges and opportunities for control researchers. The results of the research will lay the ground work for the development of cooperative robotic systems with potential applications in industrial manufacturing, military applications, environmental monitoring, transportation, space exploration, medical applications and health care services. The results of the proposed research will help the industry to offer operating convenience and increase economic efficiency, as well as offer benefit to people required medical interventions and physical assistance. Cooperative robotic systems have advantages over a single robot, such as increased dexterity, improved handling capability, increased loading capacity and enhanced robustness due to redundancy. Much existing work lacks a good framework for coordination strategies due to the complexity of the whole system. The integration of two key components, sensing and control, is not optimized and needs co-design for specific applications. The issues related to unknown environment model, dynamics, coordination mechanism to dynamic environment, imperfect sensors, communication constraints, and performance evaluation index have not been well addressed.
