A pair of devices that demonstrate new technologies in reconfigurable compliant mechanism design. These multimodal, interactive devices don't need bulky mechanisms or assembly, instead leveraging deformable plastic elements and tensioning cables.

A kinematic texture display uses a series of repeatable modules that can be individually configured to different kinematic modes, allowing complex textural information to be displayed. Control of the motors allows for the dynamic display of material properties, such as directional deformability or stiffness (i.e. mud, tough earth, stiff grass, etc.). 

A wearable haptic proxy device imitates the kinematics of weight displacement of various objects (a full rigid bar, a cup filled with rolling objects or liquid, a flexible ruler, etc.). Using only three plastic components and a pair of cabled motors, the system can configure four different kinematic modes of handheld objects. By leaving the hand open to object exploration, the weight dynamics can be added to an additional handheld device or object.
