Arduino Tracked Robot with Ping Ultrasonic Sensor

Not nearly as impressive as the CIA robots in the prior post, but this one is home grown.

Meet “FRED the Robot”:

For my die hard security fans, don’t worry, I just took a few days off of security news and finished assembling this guy. I have always enjoyed robots, and this is actually my second robot that I have built.

I made this out of a Tamiya tank track kit with dual bi-directional motors. The Wall-E looking eyes on the front is actually a Ping Ultrasonic sensor mouted on a HS-55 micro-servo. Realtime distance measurements from the Ping are sent to an Arduino control board that processes the signals, and sends control signals to the engine driver board. In turn the engine driver board converts the digital and analog signals from the arduino and moves the robot to either follow or avoid whatever the Ping Ultrasonic Sensor is tracking.

So far works great at terrorizing the cat and entertaining the kids. The short video is from two of its maiden voyages. I need to tweak the program a bit on it, as it keeps throwing its tracks when making the quick turns.

I am thinking of making it a tad bigger in the future and maybe adding a GPS unit. Not sure, just having some fun with it right now.

  2. Hi there i am working on a simaler project that involves an arduino uno and two ping sensors i was wondering if you could send me the code that you used for your bot as a reference?

    Thank you so much
