Here is my first attempt at building a hobby robot. I'm using an Octobot II platform from Budget Robotics. The MCU is a PICAXE 090 experimentor's board with a PICAXE 28X1 chip.
The Octabot II platform uses 2 R/C servos that have been modified for continuous rotation.
There is a Parrallax Ping))) ultrasonic sensor mounted on the turret. The turret has 180 degrees of movement via an unmodified R/C servo.
I've installed an IR receiver so that I can operate it by remote control, or let it operate autonomously.
I'm at the point now where I have all of the hardware operational, and am in the process of debugging my code.
Thank you everyone at LMR for the inspiration and advice.
