The mirror gripper


Stanford Excellence Award Winner


After an amazing quarter in my first college engineering class, ME20N: Haptics: Engineering Touch with Professor Allison Okamura, my partner and I wanted to make something really fun and challenging with the Hapkits we had been using. With this in mind, we designed the Haptic Mirror Gripper, which senses a user's input force on foam ball and converts it to the motion of robotic "fingers," allowing them to grasp and lift small items. Building it involved perfectly calibrating a set of motors and constructing a wearable brace for the electronics. (Full technical documentation can be found here.)


I'll never forget how excited people were at our final showcase, wearing the gripper on their arms and using it to pick cell phones and staplers up from the table.  Plus, besides being a cool toy, the gripper has applications in assistive technology, as well as in automation.
