Final Project Progress
Here’s some of the things that I’ve been working on. The image of the chair back and seat are quick renders of surfaces that I created in rhino. I am going to CNC mill these surfaces into MDF to create a more comfortable chair. Also posted is my rough circuit diagram. One IR sensor will detect approaching people. When this reads high, it will turn on an LED, which signals the person to extend his/her arm. The second IR sensor will read the height of the person’s outstretched hand, and will turn the motor on to adjust the height of the chair accordingly. The phototsensor will read when the person sits in the chair, and will turn off all of the IR sensors so that the chair doesn’t freak out while someone is sitting in it.
