For my drawing robot i first took a bowl and hot glued 6 markers on the inside, acting as a support stand for the bot. I then hot glued a battery pack that held 2 AA batteries on the inside of the bowl, this is going to power my motor. Lastly i hot glued a motor with a disk with 3 pennies hot glued to the edge of it to act as a counterweight. i then wired everything together and added a switch so i could turn it on and off. In the end it danced around on the marker supports and made a cool design featuring many many dots.
