Step Counter mission model is one of the more interesting mission models at the FIRST LEGO League 2020 RePlay competition. There is a locking mechanism that does not allow us to just push on the mission model to accomplish it, you must push it really slow and to do this 10 out of 10 times it is challenging.

In this video tutorial we demonstrate a really important concept for FIRST LEGO League competitions - you position the robot on the field with depending on timers and rotations. The issue with moving the robot for 10 seconds and then stopping is that every time it is in a different location. Same for rotations. The wheels will slip, the battery will change, something will happen and the robot will not be in the same place every time. This is not consistent and reliable.

In this video tutorial we will reach a specific location on the field 10 times. This programs demonstrates the accuracy and consistency of a program that used the Motion Sensor to detect the angle at which the robot rotates. At the end of the tutorial you will have a visual and clear picture of what you could expect from this basic usage in terms of consistency and accuracy. This might be enough for some cases and it might not be enough for others.

This M12 Water reservoir from FIRST LEGO League 2022-2023 is accomplish in two part with the Chain Monster box robot. The first part is in a previous tutorial. This is the second part where we collect the third water unit. We use a passive attachment to collect this unit.
