The following is some advice provided me by [David Anderson] of the Dallas Personal Robotics Group ([DPRG|http://dprg.org/]), which is what he called a "build sequence". It's basically a plan of action that will help anyone focus on getting their robot going, step by step.

# Once you are confident the robot can survive on its own, start thinking about other sensors. Photo sensors, (basically just a cadmium sulfide cell as half of a voltage divider connected to an A/D input[3]), in a pair pointing forward, angled slightly left and right, is an easy sensor/behavior to get working, and the results are quite satisfying. Turn toward the brighter side, perhaps with a deadzone in the center. The robot can seek toward bright lights, which change with its position, so it can apparently navigate a space quite intelligently.  Or seek away from bright lights (turn away from brighter side). This plus the bumper should give you a robot you can play with, in any space.

Now time to start thinking about higher level behaviors.  So that means going back and implementing encoders, PID, and [odometry]. Those things open a whole new world, with its accompanying complexities, so it's good to actually have a functioning robot before getting to that stage. And if one never does get to that stage, you still have a functioning robot you can play with and show off to your friends.
