Learning science in school is not always a fun activity, until something is physical and tangible. Often many of the physics and physical quantities are just numbers. How can these physical quantities and numbers become tangible. The goal of this project is to teach physical quantities such as force, velocity and momentum taking advantage of the tangibility of the shape display. The idea would be to use the pins on the shape display to emulate these quantities and help one understand and associate these quantities with sense of touch and feel.

Magic blanket is a fabric inspired by how “weak strands” transform to “stiff structure” upon weaving. It is a material which not only has programmable stiffness, but it also has memory of different states. An example application of magic blanket would be 3D scanning/capturing existing objects. As seen in the image above, a cube is engulfed completely inside the magic blanket. After the blanket is removed, the blanket takes the shape of the cube on the flip of a switch. A possible use case for such a blanket would be its use as a mold for casting.

Inspiration

Magic blanket is inspired by one of my experiments: In India, coconut leaves are available almost ubiquitously. This inexpensive natural material can be woven into a fabric, which can eventually be used for construction purposes etc.

Programmable rigidity/stiffness

By selectively  making some of the strands weak, it is possible to change the physical properties of the fabric (stiffness, hinging, creasing). The density of the soft strands and the order of arrangement of the soft and the hard strands determine the stiffness of the fabric. By selectively  making some of the strands soft, it is possible to produces hinges and creases along the fabric surface. The fabric’s malleability can be programmed such that it can be bent and twisted horizontally, while retaining stiffness along vertical direction and vice-versa.

Fabrication by 3D printing (Metamaterials)

The key idea is to embed a metal filament into the moldable plastic filament and hence the softness of each strand can then be programmed by controlling the temperature of the heating element core.

jamBoard: foldable, adaptive, pneumatic Skateboard

 

What is jamBoard ?

jamBoard is a pneumatically activated skateboard which can transform from a folded board to a full-sized skateboard upon pneumatic actuation. The key idea is to have the jamBoard fit into a person’s backpack, occupying less space and to weigh not more than the weight of the wheels. It is also adaptive in a sense that it adapts to provide suspension to the rider based on his/her body weight and riding pattern. In addition, jamBoard aides the rider in steering by sensing the intended steering direction from the feet of the user.

 

Construction

jamBoard construction

 

jamBoard has inflatable balloons sandwiched between two jamSheets. The jamSheets are flexible and foldable when not jammed. The balloons disappear when not inflated. The pressure inside the balloons is used to modulate the suspension and hence insulate the user from the roughness of the terrain. The pressure differential in the balloons predicts user’s intended steering direction. Under the lower jamSheets is a PneUIduino board that performs sensing and control of the jamBoard.

Super interesting! I wonder if the movement of the user (after for example, a jump) could create the pressure that is released by the valves? Part of the challenge here is how to let pneui quickly change the pressure, perhaps the user can assist in some intelligent way.

I joined the Tangible Media Group as a new student this Fall. Previously my work has spanned across various fields: electrical engineering (sensors and systems), informal robotics, digital fabrication and Haptics for virtual reality in the context of HCI, design and art.

I can help you with electronics, programming, digital fabrication (3D printers, Laser Cutters, Woodwork), HCI concepts.
