Video of meow-bot in action at Internet of Things build night!
Meow-bot hears sound, moves toward the sound, then meows audibly and on the LED screen. If someone is loud in the office, meow-bot will find them. I also added a temperature sensor to log the temperature of wherever meow-bot goes because some folks complain that they are cold/warm in the office.
Meow-bot is made from technic parts, self-modeled 3D printed parts to connect stepper motors to the technic parts, 2 stepper motors, LED screen, sound sensor, and temperature sensor.
Meow-bot is a work in progress. Now that I have him home, the next steps are to program turning, swap out the buzzer for a speaker, and add battery power.
