Animals like dogs, cats, raccoons, rhinoceroses, and many more get around on four legs. To help imitate this natural phenomenon, maker “Technovation” decided to create a low-cost quadruped robot using 12 servo motors and variety of 3D-printed and laser-cut parts.
Each leg features two servos that move inline with the body, as well as one arranged with its rotation axis at 90 degrees. This enables it to walk forward, scoot side-to-side, and perform a variety of twisting motions.
The robot is powered by an Arduino Uno, along with a sensor shield for easy motor connections. Inverse kinematics can be used to properly calculate servo moves, which is integrated into the device’s control sketch.
Check it out in action in the video below, and specifics are available in Technovation’s write-up.
