We have provided the building instructions for this robot as part of the whole course

One of the last things that we should mention for this robot in this module and this is the balance of the robot and how exactly the robot is balanced so that it can handle heavier attachments.

This here is the construction of the robot and if we look the robot from this side we can see that the brick is on this part of the robot along with the heavier part on the motors. So, on this back side of the robot we have the brick and the heavier part of two of the motors. The other two motors have their heavier part in the middle of the robot. And then we have the sensors at the front of the robot. This means that the whole weight of the robot is slightly to the back. And in this way when you add an attachment to the front you'll have the robot in a balance. Now, if it is a heavier attachment, it's a little bit more difficult because if we don't have these parts here that are just at the front of the robot what will happen is the following.

Now, it there is a heavier attachment and if I press here you can see that the robot will go slightly forward. So, it cannot handle very heavy attachments that are only at the front. So, you can distribute the weight of the whole attachment on the whole construction using something like this as an attachment. In this way you distribute the whole weight to the two wheels and to the back wheel. And, you can even add these two parts at the front. Like this. And this one here. And in this way even if there is a heavier attachment at the front no matter how hard you push it won't move. And in this way the robot stays in a balance. So, that's kind of the important features of this robot. In the next module of the course we'll look at how we build attachments for this robot.
