"No Fall" Toy Mechanism

https://youtu.be/Ud2lKCYvATc The "No Fall Toy Mechanism" brings back memories of my childhood battery and windup powered toys that never fell off the edge of a table or countertop, all thanks to ingenious design without the need for microcontrollers, servos, or electronic sensors. Designing this mechanism using Autodesk Fusion 360's computational features like "Center of Mass" and a scientific calculator for geometry was truly humbling. I realized that mechanical engineers in the past were incredibly skilled and talented, crafting mechanisms with drafting machines and slide rules decades ago. In the demonstration video, the mechanism is released on an 8 1/2 by 11-inch piece of untreated MDF, the same size as standard notebook paper. As seen in the video, when approaching the edge, the conical front wheels allow the front yoke to pivot, lowering the chassis front and making contact with the MDF surface. This causes the mechanism to rotate clockwise and steer away from the edge. If you have any questions, please don't hesitate to ask as I often make mistakes. One final note is that I receive no compensation for designing or using this mechanism's components. This design was created using Autodesk Fusion 360, sliced with Cura 4.4.0, and printed in PLA on an Ultimaker 3 Extended and an Ultimaker S5.
