Making Lego WeDo computer controlled motorcar from scratch

Lego sets generally come with complete easy to follow building instructions. However, it is much better if children can build new models from scratch without plans. Making a Lego Education Wedo car controlled from the computer with Lego WeDo software or MIT Scratch software is quite easy and hopefully the photos below showing how such a car can be built step by step to build a basic car base which can be added upon to customize can encourage them to create new models from scratch on their own:

Update: for a better option for building car chassis, refer to Building a car chassis from scratch part ii
