Soft-contact wall following with a roller wheel offers you some interesting possibilities. In fact, you may be able to substantially simplify the sensors and control electronics by placing an idler roller made of soft foam as an outrigger to the robot and then having the robot constantly steer inward toward the wall. This can be done simply by running the inward wheel (the wheel on the side of the wall) a little slower than the other. The foam idler roller will prevent the robot from hitting the wall.

Merely following a wall is, in essence, not that difficult. The task becomes more challenging when you want the robot to maneuver around obstacles or skip past doorways. This requires additional sensors, perhaps whiskers or other touch sensors in the forward portion of the robot. These are used to detect corners as well. This is especially important when you are constructing a robot that has a simple inward-arc behavior toward following walls. Without the ability to sense a wall straight ahead, the robot may become hopelessly trapped in a corner.

Open doorways that lead into other rooms can be sensed using a longer-range ultrasonic transducer. Here, the long-range ultrasonic detects that the robot is far from any wall and places the machine in a go straight mode. Ideally, the robot should time the duration of this mode to account for the maximum distance of an open doorway. If a wall is not detected within x seconds, the robot should go into a look for wall mode.

33.3 WALL FOLLOWING
when required (such as when a wall is in front of the robot). The following program is optimized to eliminate some of the decision making for the slow versus hard turns in the first 15-ms portion of the PWM operation; in the second part, the decision is made whether or not to turn the motors off for the full PWM cycle.
' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' BS2 Line Follow - Wall Following Software This software takes the inputs from two Wall sensors/Whiskers (one at the side and one in front) to control a robot following a wall on the left hand side of the robot. A simple 30 Hz PWM has been created for the robot with the following responses to the inputs: Left Whisker Contact No Contact No Contact Contact Front Wisker No Contact No Contact Contact Contact Left Motor Full Half Full Full Right Motor Half Full Zero Zero
