Would you like a dog? Would you like a robot dog? If so, then this build by Michael Rigsby could be a great starting point.
Rigbsy’s robotic pet features four servo-driven legs, with two-axis shoulder movement, as well as an articulated knee joint. As seen in the video below, it’s capable of picking itself up off the ground, and can then walk using a slow side-to-side gait.
An Arduino Uno uses the majority of its I/O pins to control the legs, and as of now, it travels forward with no directional control or sensor input.
Instructions for the project, along code and 3D print files, are available in Rigsby’s write-up.
