Hey everyone, I'm new obviously and I have no knowledge in physics at all, or engineering at that, but plan on getting into robotics engineering. I'm still in high school so I'm pretty ignorant with all of this guys so bare with me. I just have a question and am not so sure how easy/hard it would be to do. I want to be able to make, say, a remote control car be able to ride on a vertical wall. It's a project (a personal project, not a school project) I want to work on, but I need to be able to make a pretty heavy object stay on a wall and move freely around the wall. Even more difficult, the faster it is able to move the better. So....umm have at it guys. I'll probably roam around these forums for a while because you guys talk about some really interesting things.
