In this part of the project the pupils create a mechanically controlled car. In the  international teams they make a similar car. 

Every international group consists of 2 sub-groups:

• 2 pupils of class 3 WETa or b  and 2 or 3 pupils of class 7A
• 2 or 3 pupils of class 3WETc and 2 or 3 pupils of class 7B
   

These are the conditions with which the car is to comply:

• Only mechanical components are allowed, no electronic parts!
• The car can drive independent (a short distance will do). The car may be helped to get started, f.e. being pulled back to wind up a spring.
• Some of the parts must be changed in order to control if the car runs faster, longer, …. (f.e. bigger wheels, a larger elastic, other cogs, …)
