American engineers have created robocell consisting of
zamachivaem modules, each of which is driven by using the actuator
on the basis of liquid — crystalline elastomer- a polymeric material that combines
the properties of liquid crystals with the elasticity of the elastomers. Such actuators can
be used for mechanisms and robots, the motion of which is associated with
by bending, for example, built with the technique of origami, says in an article accepted for publication in the journal Smart Materials and Structures.
The ancient Japanese art of folding paper , origami has attracted the attention of engineers who apply the principles
the underlying technology for the creation of structures and mechanisms, able
to change its shape. For example, used deployable structures for space
the devices, which in collapsed form is the smaller volume to make room for other payloads.
For the propulsion of robots and mechanisms, whose morphology and
functions based on the concept of origami, the necessary actuators to ensure efficient
flexion and extension nodes. Mechanical actuators in devices with a large number of bendable nodes greatly complicate the design, as pneumatic or hydraulic
actuators uncomfortable because of possible leaks. So scientists are looking for new materials for this task.
American engineers, under the leadership of Adriana Minori (Minori Adriane F.) and Michael Tolly (Michael Tolley T.) has developed a multilayer
somogyvamos the actuator on the basis of polymeric material that combines elasticity
with properties of self-organization of liquid crystals — liquid crystal elastomer. Polymer
chains in this material formed sternvitamin structures known as
the mesogenswhich are able to change their spatial orientation.
