https://www.youtube.com/watch?v=LSzr4zX_RG8 this video is a differejnt type of video as the ones before. this video would help me on making a small type of robot. robotics aint that hard to make but you have to be smart. you would also need to have some advance materials. you would probably need a special help by your teacher if you under age. this video was a good reference to my project. because it have some easy steps.
