Abstract :

Octopuses where always a fascinating animals with their spectacular line of unique features. Here will review many of those features focusing on the arm motor control. Similar to tongue and the elephant trunk, the octopus arm is a muscle hydrostat, hyper redundant, structure. The computational process involved in the generation of a movement in such structure is a highlight for motor control engineers. During that process, a reduction of the motor control problem complexity is obtained by reducing degrees of freedom, using stereotypical motor primitives, which are simply modulated instead of calculated, to achieve the required movement. That principles inspired many robotic engineers to achieve new kind of control: embedded intelligence. Here we will present some results of such bio-robotic engineering and novel applications.
