My house's lighting system is redesigned such that they recognize and respond to the events taking place.
Next generation Microsoft Surface device
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.
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.

We propose pouch motors, a new family of printable soft actuators integrated with computational design. The pouch motor consists of one or more inflatable gas-tight bladders made of sheet materials
In this project, we designed a tilting head for a water jet cutting machines that compensates taper angles on thick materials during cutting. The cutting head tilts around a remote center of rotation.

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-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.
Through RC car product design project, we learned design for manufacturing and aseembly

I used google calendar API and integrated to an alarm clock such that a user can view daily schedules without having to open a computer.
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.
Magic Bowl is an educational toy. It teaches five-graders the mathematical concept of "ratio" by blending colorful lights.
Nature-Dream is a pillow that helps to regulate the circadian rhythms and improves the sleeping experience. it creates a natural environment around the sleeper with sound, light and aroma. it is comprised of a pillow with electronic embedded.
I worked as a student researcher designing a dynamic solid state lighting fixture for smart lighting research.
ed.it is an efficient sustainable, interactive and wide-reaching learning management system for educational institutions. It is designed for the Windows 8 framework and meshes with integrated Administrative Computing Services.

Our design team wants to push the aesthetics and usability as far as we can on an everyday object, and make the prototype as mature and complete as one that can buy from a store. We want to apply the design principles that we learned from the book to an actual project.

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.
