  It completely depends on what level of robot you want to make. To make something go from right to left and from up 2 down is very very easy. Then if you want to add wireless controls to it, hardship increases. Then you can have a video camera attached to it which makes it even more harder…and the list goes on and on and on……….

  I’ve never tried, I’m sure there must be videos on youtube to show you how though!

  I’m with Leila, I’d look it up on youtube or ask someone like Dhvanil who has lots of experience! Thats what science is about, networking with people who know more than you do!
