# 10 runs on precisely turn with acceleration and Motion Sensor from LEGO Education SPIKE Prime ProPreview

In this video tutorial we take a look at the consistency of a robot that uses acceleration and deceleration to turn precisely. We use the motion sensor. In 10 consecutive runs we demonstrate what could you expect from the robot when it comes to consistency.

In this video tutorial, we will do ten consecutive runs with the LEGO Education SPIKE Prime Robot and explore how accurate our program with acceleration and motion sensor is. Can we be consistent with the robot behavior? The goal of this ten consecutive runs is to see how consistent the robot could be. First, you can watch the back wheel. There is a wheel at the back of the road that's on the left and you can see that it arrives almost every time exactly at the same location. So what this program does is it moves the robot and it tries to rotate to about 90 degrees and rotate to 90 degrees. It accelerates in the first 45 and then decelerates in the next 45. So this acceleration and deceleration prevents the robot and its wheels for slipping on the map. And in this way we have a pretty consistent behavior for the robot. You can see that almost every time the robot is at the same location. This is one of the tools that we like to use the most. This block with acceleration. You can copy paste it, you can take it for all your programs. But this block has brought us a lot of consistency in different programs when we try to accomplish different FIRST LEGO League missions. You can check out the previous tutorial with the explanation of how exactly we programmed the robot, and as an end result, I could say that we have a pretty consistent behavior of the robot.
