LEGO MINDSTORMS EV3

In this episode we do a full run of the mission for collecting a single treasure before going into explanation on how we have programmed the robot.

In this second video lesson on catapults we improve the stability of the base of the robot. An important feature of the new base is that it is not bending. Use the same principle in all of your constructions to achieve better, stronger robots.

The most stressed wheel in our system is the driven wheel. We've already fixed the problem with the driving wheel of the scissor mechanism and now it is time to look at the drive LEGO Mindstorms wheel. 

Let's implement a more advanced program for this robot to learn how to use with motors in opposite directions - and this is to implement the Proportional Line Following algorithm.

In this tutorial, we demonstrate how to square on a wall. The process requires the robot to crash into the wall, or another solid object on the field, and to "stick" on it. If the robot was to an angle to the wall, the final result of that crush will be that the robot is now fully perpendicular to the wall. As we say in competitions - the robot has squared or aligned itself.

Here are the conditions your robot is evaluated under in order to qualify as a good solid construction.
