House party lighting

As part of my house lighting system redesign plan, this sub-project controls the lights to mimic some clubbing light effects. A computer's mic is used to detect beats in 6 - 10 frequency ranges. One light coresponds to one frequency range. Once a beat is detected, the computer sends a "strobe" effect to the light. Range of avaliable colors are preselected based on the playing song's style.

Printable pneumatic actuators for soft robots

We envision future electro-mechanical devices can be printed on planer structures and folded autonomously for robotic applications. This thesis project is devoted for the development of self-folding and actuation of such robots, with a novel actuator called pouch motors. Pouch motors is a family of printable pneumatic actuators in the pouch form that drives motion with inflations and deflations. It is customizable in design, inexpensive to fabricate and planer in nature, making it ideal for origami inspired robots.

Printing angle sensors for foldable robots

Self-folding is a promising technique for assembling robots from flat sheets. However, existing implementations do not include reliable methods to fold and actuate accurately with feedback control. In this paper, we present novel angle sensors for foldable robots and machines. They are inkjet printed and fully integrated into robots’ laminate. This additional sensor layer tracks the angle motion of robot hinges, to better guide robot assembling by folding and to perform more complicated tasks that requires feedback control, making folded robots more capable in real world applications. We introduce the fabrication process, property assessments, and demonstrate sensor performance by measuring folding angles of a cube and controlling folds on a gripper.

Self-folding and self-actuating robots: A pneumatic approach

Self-assembling robots can be transported and deployed inexpensively and autonomously in remote and dangerous environments. In this paper, we introduce a novel selfassembling method with a planar pneumatic system. Inflation of pouches translate into shape changes, turning a sheet of composite material into a complex robotic structure. This new method enables a flat origami-based robotic structure to selffold to desired angles with pressure control. It allows a static joint to become dynamic, self-actuate to reconfigure itself after initial folding. Finally, the folded robot can unfold itself at the end of a robotic application. We believe this new pneumatic approach provides an important toolkit to build more powerful and capable self-assembling robots.

Sticky Actuator: Free-Form Planar Actuators for Animated Objects

We propose soft planar actuators enhanced by free-form fabrication that are suitable for making everyday objects move. The actuator consists of one or more inflatable pouches with an adhesive back. We have developed a machine for the fabrication of free-from pouches; squares, circles and ribbons are all possible. The deformation of the pouches can provide linear, rotational, and more complicated motion corresponding to the pouch’s geometry. We also provide a both manual and programmable control system. In a user study, we organized a hands-on workshop of actuated origami for children. The results show that the combination of the actuator and classic materials can enhance rapid prototyping of animated objects.

Paperless pen

The paperless pen is a device that could be used to display and store information with photosensitive paper. The pen uses UV light printing technology to write and print. The texts on photosensitive paper will disappear within 16-24 hours and make the paper reusable. The pen also has a portable scanner embedded. this combination allows user to share information with simple swipe actions. this is a conceptual design project.
