Title:            Actuation of an origami inspired curved-crease gripper with a
                     planar bending actuator         

Folding paper using origami techniques has been picked up as inspiration by engineers. A particular design choice is to use curved creases. By folding a curved-crease design, the sheets connected to the crease line have to bend, allowing for novel properties unachievable with straight-crease origami. While most important favorable properties are preserved: origami mechanisms can be manufactured with precise planar methods and can easily be adapted for the individual user.  Actuated origami mechanisms are usually actuated on the crease line, where space is limited. 
A new method to actuate these curved-crease origami actuators is presented. Planar bending actuators, attached to the faces of the crease pattern can fold and actuate the design. We expect that this method can be used to design origami mechanisms that can handle higher loads. This method is evaluated by the analysis of a curved –crease gripper, a small origami robot that can be opened and closed remotely. The performance of the gripper is analyzed experimentally and numerically. From our analysis we conclude that curved creases perform better than straight creases , provided that the crease pattern or the surface material ensures that the moving of generators along the surface is minimized.

The presentation will be given in English.
