• Robot Base Chassis

"Sometimes it works, sometimes it does not work" - this is the most common case in FIRST LEGO League competitions. In this tutorial, we demonstrate and discuss such a case where the first part of accomplishing the mission always works but the second part has about 60-70% success rate. The robot is not very consistent. Let's take a moment to see it and explain why so that we can resolve the problem in the next lesson.

In this video tutorial, we use the motion sensor and demonstrate 10 out of 10 times how we can keep the robot moving in a straight line. The program is described in the previous tutorial in the lesson where we enter into the programming. Here we visualize how consistent and reliable the behavior of the robot is.

This is a 10 out of 10 tutorial for pushing gently on a mission model. We also discuss how to build robots that tolerate error and auto-correct their behavior.

Continuing from the last tutorial, we demonstrate the consistency and reliability of the robot when we don't user sensors. The result is pretty obvious - the robot is NOT consistent and reliable. It just makes a lot of mistakes
