Mechanical Whiteboard Cleaner

We know that our project still has a few more things to be improved, for example, the smooth movement of the eraser and its contact problem, but we are very happy it works.

More importantly, we have learnt a great deal about working as a team, coming up with solutions (even ridiculous ones) whenever we hit a snag, being responsible (we sacrificed our extra-curricular activities) and never to give up.

We really enjoyed the sandpapering and hammering which we had no chance of experiencing at home. Just imagine, we did not even know how to hammer a nail into wood and use a screwdriver correctly!
