Rocking Body Walking Robot Drone #5

thingiverse

This is a simple 3D printed walking robot with a distinctive rocking body action. Powered by a Tamia Universal gear box and 2 AA batteries, it can be equipped with an LED or small lamp for added illumination. The Pin walking design utilizes a linkage that pushes down through the feet in a concentric motion to create a walking motion. The feet are designed to pivot side to side, ensuring stability while allowing the robot to walk smoothly. Two cams control the body tip action by pushing against "stops" within the main body part. A total of 11 STL files are provided, with some parts requiring duplicates such as legs, feet, cams, and linkage units. The legs are glued to the motor frame, while two small cap parts secure them to the feet, allowing for pivoting movement. The battery holder is a standard 2 AA type, which is glued into the main body part. The front and back sections are secured with screws. The Tamia Universal Gear box comes with mounting screws and includes two types of drive shafts: the hex drive shaft for walking and tipping cams, and the round shaft, which will be cut down to serve as a pivot shaft for the motor frame unit.
