Evaluation

Overall the box works well despite the wooden exterior. The internal system almost works as it was designed to. There are, however, two aspects that it fails to do; slow down and achieve the desired distance.  
 
The resistor is not powerful enough to slow it down like we intended it to. This is due to an error with our initial calculations. 
 
It was supposed to travel 30cm but it only travels 14cm. It does not travel 30cm because we changed the diameter of the wheel. The wheel was changed to enable us to move the rear drive wheel further back proving more stability. We needed more stability as the box only has 3 wheels. 
 
I feel that it is better that it doesn't travel the full 30cm as it is suppose to be used on a desk and if it travelled 30cm it might run the risk of falling off and being damage or damaging something else.
