Some legged robots end up moving with ponderous deliberation, or wavering in unstable-looking jerks. A few unfortunates manage to do both at once. [MusaW]’s 3D Printed Quadruped Robot, on the other hand, moves in rapid motions that manage to look sharp and insect-like instead of unstable. Based on an earlier design he made for a 3D printable quadruped frame, [MusaW] has now released this step-by-step guide for building your own version. All that’s needed is the STL files and roughly $50 in parts from the usual Chinese resellers to have the makings of a great weekend project.

The robot uses twelve SG90 servos and an Arduino nano with a servo driver board to control them all, but there’s one additional feature: Wi-Fi control is provided thanks to a Wemos D1 Mini (which uses an ESP-8266EX) acting as a wireless access point to serve up a simple web interface through which the robot can be controlled with any web browser.

Embedded below is a brief video. The first half is assembly, and the second half demonstrates the robot’s fast, sharp movements.

We love it when robots show some personality, like this adorable little quadruped robot that can make small jumps.

Thanks to [Baldpower] for the tip!

Hey guys,
Just found out about LMR and wanted to share some of the robots we have made in past. (so, I will post 4-5 more projects soon)

Jeffrey The Quadruped is a quite small walker with 4 legs. It has printed circuit board with a custom arduino setup, using an Atmega328.
It has a Sharp IR Rangefinder attached on 2 servos and uses a simple rotational object tracking algorithm to let him create temporary low resolution visual maps. This way it can stay on a table, stay away from objects and even track your hands with a single sensor.
