Summary
In this chapter, we have added sensors to our robot. This is a major step as it makes the robot autonomous, behaving on its own and responding in some way to its environment. You've learned how to add distance sensing to our robots, along with the different kinds of sensors that are available. We've seen code to make it work and test these sensors. We then created behaviors to avoid walls and looked at how to make a simplified but flawed behavior, and how a more sophisticated and smoother behavior would make for a better system.
With this experience, you can consider how other sensors could be interfaced with your robot, and some simple code to interact with them. You can output data from sensors so you can debug their behavior and create a behavior to make a robot perform some simple navigation on its own.
In the next chapter, we look further into driving predetermined paths and straight lines using an encoder to make sure that the robot moves far more accurately...
