The Bug-Bot
John-David Warren, Josh Adams, Harald Molle · Apress eBooks · 2011
In this chapter you build a robot (the Bug-Bot) that uses bump sensors to navigate around objects and explore a room, much like an insect would. The bump sensor is nothing more than two wires pressed together when the bot bumps into something, to let the Arduino know that it needs to find a new path (Figure 7–1). These sensors are commonly used for object detection but require that the bot have physical contact with the object to detect it. Some robots incorporate several types of sensors for object avoidance and autonomous navigation; these usually include a bump sensor on the front and/or rear of the bot to stop it if the other sensors do not. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
