A 100% winning Janken laser light hand based on galvanometer mirrors

Final project for 2.171 Digital Control Systems @ MIT

11/2015-12/2015

  • Measured the plant dynamics and fit the bode plot with a second-order system

  • Designed a discrete-time lead, lag and proportional controller which has a crossover frequency of 200Hz and a PM of 60 degrees

  • Implemented the controller with Labview, NI myRIO, power amplifier and a circuit

  • Used Matlab to generate trajectories for rock, paper and scissor patterns by image processing of real hand gestures photos

  • Used Matlab to continuously read the video streaming frames from a webcam, recognized human gestures by image processing and normalized standard cross-correlation with template pictures

  • Sent data from Matlab to NI myRIO via TCP/IP by enabling WiFi in myRIO
