ABSTRACT
In this paper, we describe the design and development of shapeable figures filled with polystyrene beads. We discovered we could create solid objects by the extraction of air from a container filled with small polystyrene beads. These objects were easy to shape. They also maintained their shapes after formation. We collected feedback about the formability of these objects by the insertion of pressure sensors. We were also able to control other devices, such as LEDs and DC motors, based on data collected by the pressure sensors. When we controlled the DC motor, we were able to regulate the air pump's power. This allowed us to control the objects' hardness by modulation of the volume of the air inside them.
Our method can be employed with applications that require shape manipulation. We applied this method in the construction of a doll figure and a boot. We used "stuffing beads" to create a larger doll shape that can function as a bone inside the doll. The doll prototype's shape could be changed manually. The boot could be adjusted to fit the shape of the user's leg.
