one of my students told me about a shop that has metal wind up robots for sale. the shop is really a clothing boutique, but they had some robots. so i got these two. there were others i would have liked to have too, but they were too pricey. these two were cheaper and i’ve always wanted a robot sort of like robby. he would have been cool just as a wind up robot, but the fact that he shoots sparks makes him even cooler.
