There is almost nothing we should add to or remove from this robot. It is stable, it has the frame and attachments could be easily added.

The motors direction could also easily be changed. 

The whole construction is separated in different modules that allow for fast assembling or disassembling.

I would like to give you an idea for one more robot and you can find the instructions below the video of course. This is the robot that I probably like the most from the five that I'm demonstrating in these series of videos and these are some of the reasons why.

First, the robot is very small, it uses a very small amount of parts and it's a square robot. This makes it very well balanced.

That makes the robot very interesting. Small, square robot with a few parts and the other thing that I like very much in this robot is that I cannot think of anything to add to this robot and to change in this robot, it's nearly perfect and we can align to different walls, we have the sensors at the front of the robot, we have the wheel and we have the 2 motors, at the sides of the robot. Because of these 2 motors the whole robot is valuable and balanced. In some of the EV3 sets you have only one of the motors and you can decide to place the motor here or to place it here. You can also change the position of the 2 motors. So you'll have enough space to change the position of the motor and you can have, if you have 2 motors, one of the motors pointing to the front of the robot and the other one pointing to the back of the robot. This makes the robot very, very interesting. Let me just return this to initial position. It's a very good starting point if you want to use a small robot and to add small attachments to this robot. If you have missions where you can add an attachment on the front and the back to keep the balance of the robot. The other thing is again this robot is using wheels from the NXT set, not the EV3 set but it can be easily modified to use the large wheels from the EV3 set. In many cases when we have the opportunity we'll use the small wheels because it seems that we can achieve a more stable robots with smaller wheels. That's not always the case, but in some of the cases. And the last thing for this robot, it has the axle on which the wheels are rotating, connected on 2 places and this makes the axles very, very stable. Very interesting robot. It's again build with modules and these red pins and you can just remove the pins and if I remove all 4 pins I can remove the motor.

If you use it as a base for your robots, do not hesitate to share this with us.
