If you’ve been following along with our previous articles, you’ll be familiar with making your robot drive around, as well as some basic use of the sensors.  This article will now focus on the Medium motor that you get with the EV3 kit and how it can be used as a powered attachment for your robot.

When using just the Move Steering blocks, we are always directing the robot to do a specific set of movements.  This is often called ‘dead-reckoning’.  The problem with dead reckoning is that, should anything get in the way of the robot, it has no ability to realize this and will blindly continue to follow its given instructions, regardless of what is happening in the real world.

One of the most important commands we can give a robot, especially a moving robot, are commands that tell the motors what to do. This article will show you how to build a simple robot and get it moving accurately.

So there was a question that came through the EV3 Facebook group by Ana 
"Hello! Has anyone tested (or is there any documentation about) the line width that the EV3 light / color sensor is capable of reading? "

Having just finished up a project and looking for something small to help me procrastinate about starting my next big task, I thought "This is an awesome way to waste time / learn something new".  And while knowing the answer is very helpful, I'm also really keen to learn from the process of getting the answer and figured the datalogging capability of the EV3 would be perfect.
