Build: "Otto" : The 6th "Mindstorms Robot Inventor" Model

The main idea of this project is to propose a 6th model to the "Mindstorms Robot Inventor" Lego set.

So, this car is only build with parts from the set 51515 : no one was added from another set.

With my 42 years old, I creater the car, but I am very bad in programming, so it's my 9 years old son who created the program.

I wanted the more compact car possible, I think it's complicated to make more compact than this one (that we name 'Otto").

My son created a program that non only allows the car to drive ahead and back, and to turn right and left, but also there is an horn which advise when an obstacle is on the way !

Very usefull addition, thanks to the Mindstorm ultrasonic sensor.
