Mind boggling! It’s all done with some form of logic controller. Think about all of the systems that have to be controlled in a single work cell in a factory… then multiply it by 10’s or 100’s of cells. The next tutorial: OpenCV with Raspberry Pi Camera Face Detection Tutorial - Robotics with Python Raspberry Pi and GoPiGo p.When you think about it, in manufacturing, controlling things is necessary to perform very complex tasks to manufacture items to tolerances finer than a human hair.

Not too shabby for such rudimentary code! Now, our robot has "eyes," but only we can see through them. If left_dir > right_dir and left_dir > min_distance:

This puts our full script to: from gopigo import * Now all we need to do is call things to run: stop() The only action that will continue is moving forward. We do this so last actions are not just repeated. When we're done with the reversing, we're also going to spin in a random left or right direction. Since we came from "backwards," we're assuming this will be safe, but we're doing this totally blind. If neither direction is greater than the minimum, then we decide our last choice is to just move backwards. If both are greater, then we go the direction that is the largest. If one of the directions is greater than the min_distance value, then we go that way. Rotation = rot_choicesĪfter having gathered the distance measurements of the left and right directions, we can then make some educated choices. if left_dir > right_dir and left_dir > min_distance:
Next, we use the servo to look left, and look right, gathering distance measurements. Here, we have detected that moving forward is a bad idea. If that distance is greater than the minimum distance that we require, then we're fine to just proceed forward. Next, we grab the current distance between us and the nearest object in front of us. Later on, we might have the robot just disable itself if there is a problem, or, better yet, enter some sort of problem solving phase that attempts to extract itself from the issue. We start this while loop, under the condition that there is no problem. Next, we just begin to build the logic for handling issues that we cannot figure out. For example, as you will see, setting 70, for 70cm, usually results in us stopping just barely short of smashing into the wall, because of our logic, which lets us move blindly for "x" amount of time. You should choose a number much larger than you really think you want.
We set "min_distance" to a value that we want to be the "minimum" distance between our robot and an object it detects. To start, we grab the GoPiGo software, import time, and import random.

While remote control is cool, autonomy is cooler! In this robotics programming with Python, the Raspberry Pi, and the GoPiGo tutorial, we'll be covering how to begin to program our robot to interact with the physical world all on its own.
