Below is a diagram of the parts of a lever. For most of these robots, the fulcrum is at the tip of the arm. This allows the robot to have its tip reach the floor in most cases. All of the robots below include at least one lever. The machine that has the most levers that we have seen is Disector who has five, two on the sides of the robot and three that make up the jaws.
Most people think that a lever needs to be straight like a teeter totter.
Toro is a good example of a lever with a bent arm. It's good to see that some robot builders were able to use a modified lever form to meet their needs. This robot uses the area of its body between its wheels as the fulcrum for horizontal movement and its wheels as the fulcrum for vertical movement. The use of its body as a fulcrum allows Blade Runner to reach incredible speeds at the end of its spike. The following robots all have a fulcrum and at least one arm.
