It is hard to seperate sensors and actuators in biological beings. Spindles and tendons are parts of muscles, and mechanoreceptors are a part of soft tissue. This means, pysical dynamics of soft tissue and musculo-skeletal structures and perception are intrinsically coupled. This offers the advantage of conditioning sensors to suit a task. We have taken a soft robotics approach to understand more about this. Here are some of our publications in this area:
