My plan: Building a 8 servo quadruped(to be decided) that will have an Arduino Uno controlling the servo's and an Attiny(either 85 or 2313) doing the "processing". A ping sensor will be mounted on a micro servo. Ping data goes to the Attiny and the servo is also controlled by Uno.
When an obstacle is too close to the robot, the ping servo will rotate right, log the distance, left, log, and then the bot will turn in the direction(most likely 90*) with more clearance.
This is a simple idea, and impractical(I just want to do this for fun).
What are your thoughts on my idea, and is there anything I can do to improve it? I won't remove attiny, because part of what I want to do is the serial communication between the MC's.
Yes, but not nearly as complex. From what I've heard, that "Big Dog" uses GPS to navigate now. Not to mention it has many more, very costly servos.
I plan to make something smaller, either using standard or 9g micro servos. Perhaps I may mount a wireless camera and an XBee module to have drone-like control, with the help of my due and processing.
