Topic:
Soft Actuation technologies for physical Human-Robot-Interactions
Abstract:
The ever-growing demand of wearable and mobile electronic devices, electric vehicles, grid-scale electrical storage, and other energy storage systems requires the advancement of lithium (Li) batteries of high energy density and improved stability and safety. One of the most promising approaches is to replace the existing graphite anode in Li-ion bat
The requirements for actuation technology suitable for rehabilitation/wearable robotics are fundamentally different than those for industrial robots. Operation at close vicinity to humans, safety is of the foremost concerns for rehabilitation robotic platforms. In addition, the ability to store and release energy, which does not exist in the industrial actuators, is greatly beneficial for rehabilitation robotics, especially for repetitive tasks such as walking. Furthermore, being able to adjust the mechanical softness in rehabilitation applications is a plus if not a must! Understanding the working principles and mechanical properties of biological actuators, i.e., skeletal muscles, are key in realizing suitable soft actuators for rehabilitation applications. “Soft actuators” is an emerging field in robotics that has shown promising advantages for rehabilitation applications over traditional robotic platforms.
In this talk, some of the recent advances in developing soft actuators will be discussed and pros and cons of these new soft actuators will be highlighted, towards bringing some insights into the future artificial muscles that can match performances of the skeletal muscles. Finally, some future research directions will be presented that try to understand how humans adjust their mechanical stiffness to cope with different situations in our daily life. Understanding these coping mechanisms is vital in order to develop new robotic prosthetics/exoskeletons for mobility impaired people and amputees.
