This week we are working on the demo for the last presentation of the semester. Last week we designed and ordered our second PCB iteration and made minor changes to the design by adding LEDs to make up for the pins lost in RSLK horizontal header. This PCB will be incorporated in our demo and enable us to debug efficiently. The demo will utilize the IR LED sensors and change the color of an RGB LED on the top of the DSP depending on if the surface is black or white. The demo will also utilize the microphone on the AUDIO-XL booster pack and halt the robot for a few seconds anytime the input goes above a certain threshold. To incorporate the motors and bump sensors, we plan to have the robot move forward until it hits a wall at which point it will backup and turn 45 degrees in the opposite direction of the wall and continue on.
