In this project, we built a robot from scratch that can autonomously collect coins, deliver and dump the coins to designated locations, and compete with other robots. The project gave me a thorough experience in circuit design, sensor integration, motor control and programming of embedded systems.

This started as a course project for Stanford "Mechaphonics" class where I made a quadcopter that can be controlled by an Android phone via Bluetooth. Later on, with a few friends, we decided to extend the project and do something fun. We developed automatic hovering and human face tracking for the quadcopter. With an additional smart phone mounted on the quadcopter, it can follow and take video of a person.

In this project, we designed and built a smart actuator that can be attached to common window blinds to automatically turn and adjust the window blinds. The device can be controlled by a smart phone. It can adjust the angle of the window blinds to maintain a certain light level in the room. It can also automatically turn on/off the window blinds based on time/user preference.

In this project, we made a soft hpatic interface that is wearable on fingers like a cuff. The haptic interface is capable of rendering different pressure. This haptic device can be used for sensory substitution. We did studies showing that users can distinguish different level of gripping force in teleoperation with pressure feedback by our device.
