Here we start with a second box robot that we would like to build. It is in a way improvement to the first robot and we would take a look at its features. 

Cable management is very important on each competition. Cables could get in the way of attachments, levers, different wheels and so on. Brick accessibility is also very important. Do not forget that the brick should be charged from time to time and that you should also be able to access the buttons. 

With the EV3 Mindstorms set you receive three motors. Two are large and one is medium. These three motors could be used in different configurations and in this video we show how to use the motors on the second box robot for competitions that we build. 

One of the very good things about box robots is that you could easily align with them both to the front, to the back or to the rear sides. This aligning is helpful for FIRST LEGO League, World Robotics Olympiad or other robotics competitions with LEGO Mindstorms EV3/NXT robots. 

This robot has a color sensor and this sensor is used for following lines. Additional Mindstorms EV3 sensors could be place on the robot, like a Gyro sensor or a second Color sensor.

Where should you lift the robot? Especially if you don`t have the mission model that we are using

Don't limit yourself to the box and think of different ways to lift the robot. 

Build a robot base to use in the course. You can use the robot base provided by us or you can build one yourself. 

Time to lift the robot. The first approach is by using the 40 teeth gear wheels that come with the LEGO Mindstorms EV3 and NXT robotics sets. 

Build a similar mechanism to this one. Similar, but for your robot. This is the task for you. Try, give yourself half and hour or even an hour.

How to align the wheels and how much should you push for this solution?

Build a rack and try to lift the robot with this rack. 

In this tutorial, we would drive the scissors mechanism and there are a number of rules that we must follow

Let us do a quick recap of the whole lifting mission and its solution

In this Episode, we stop at the pinless attachments for the Box Robot 2 and especially for the constructing a frame. This frame is then used for further extending the robot with attachments.
