My First Robot

Yesterday, my team and I built a robot out of a blue LED fan and crayons. What we did is we cut 3 blades of so it would be unblanced and have a vibrating motion. Then we attached 4 crayons to it so it would have legs. Atleast thats what i thought at first. THen i relized that we have to use the crayons to draw squiggly lines on a paper.  THe fan was powered by a 9 volt battery
