Human-robot shared control for split-site interaction and disabled assistance

The context where the robot will be used leads to understanding the interaction requirement among the robots and between the human and robot. This includes the number of humans and robots to be used, the task to be solved, and in several cases, the human is expected to assist the robot in overcoming the limitation in robot performance. Numerous factors are nominated for the robot to be successful, such as the repetition to reach regular quality, the speed and the force of manufacturing robots, reduction of the task hazards, decrease of the force required and flexibility in programming. The estimated number of multi-task robots around the world is about 1,664,000 as reported by the International Federation of Robotics (IFR) statistical analysis. The industrial robots continue to develop in both safety and productivity; moreover, while they have evolved in their functionality, safety is a hugely significant concern. Since the risk of injury is the most crucial factor for the human-robot interaction, the soft robotics technologies provide significant alternatives for rigid robots. The soft actuators that made as a human-like muscle such as the pneumatic muscle actuators (PMA) are used to design such type of robots. The main advantages of the PMA are the high force in comparison of its weight, multiple degrees of freedom (DoF) without joints, small workspace required and it is safe for human-robot collaboration.
