Improved this exercise to go faster.
a) Case 1: Turtlebot is going straight ahead without obstacles:
b) Case 2: Turtlebot is avoiding obstacles while it is driving to its target:
We can take a look to the VFF obstacle avoidance exercise, using the real Turtlebot.
Due to the limitations of the enviornment, a new approach to the solution of the follow-line has been tested, in which the (white) line is being left to the right of the robot.
The noised caused by the Turtlebot structure's sticks has been solved, so I've been working on this second prototype, which is better than previous one, because the shelf is now clean, which allows to put the PC on top of it.
The Turtlebot structure includes four sticks which are causing noise into the laser measurements. So, I am testing this new prototype.
I've been testing this new laser for the real Kobuki robot, using a Python ROS node called "view_rplidar". It works so fine!
I'm testing a new approach to the solution of the follow-line, in which the (yellow) line is being left to the right of the robot.
I start this new year with a new exercise: the classical follow-line, with Kobuki. I've created a ROS node to communicate with the real Kobuki and the simulated Turtlebot in Gazebo.
