    DIY quadruped robot brought to life for under $60

    Arduino Team — October 10th, 2020

    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 a 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.

    GoodBoy is a robot dog that runs on Arduino

    Arduino Team — May 27th, 2020

    Daniel Hingston wanted to build a four-legged walking robot for several years, and with current coronavirus restrictions he finally got his chance. His 3D-printed robodog, dubbed “GoodBoy,” is reminiscent of a miniature version of Boston Dynamics’ Spot, which helped inspire the project. 

    It’s extremely clean, with wiring integrated into the legs mid-print. Two micro servos per leg move it in a forward direction, controlled by an Arduino Uno.

    Obstacle avoidance is provided by a pair of ultrasonic sensor “eyes,” allowing it to stop when something is in its path. An LDR sensor is also implemented, which when covered by its human minder commands it to present its paw for shaking.

    Be sure to check out a short demo of GoodBoy below!

    Arduino Team — May 25th, 2020

    Gregory Leveque has created an adorable 3D-printed robot that not only walks on four legs, but folds up into a ball when not in use. 

    To accomplish this, the round quadruped utilizes one servo to deploy each leg via a parallelogram linkage system and another to move it forwards and backwards. A clever single-servo assembly is also implemented on the bottom to fill gaps left by the legs.

    The device is controlled by an Arduino Nano, along with a 16-channel servo driver board. Obstacle avoidance is handled via an ultrasonic sensor, which sticks out of the top half of the sphere and rotates side to side using yet another servo. 

    It’s an impressive mechanical build, especially considering its diminutive size of 130mm (5.12in) in diameter.

    Baby Cheetah is a mini, MIT-inspired quadruped robot

    Arduino Team — October 29th, 2019

    Since we can’t all have the MIT Mini Cheetah at home, Jegatheesan Soundarapandian decided to make his own version — measuring just 23 cm x 9 cm x 9 cm.

    As shown in the video below, the aptly named “Baby Cheetah” does an amazing job of getting around on four legs, and is not only able to walk upright, but can even move at a crouch, turn, and tilt forwards or backwards.

    The robot is equipped with eight SG90 servos to actuate each 3D-printed leg linage assembly, giving the limbs excellent mobility in a vertical plane. An Arduino Nano is used for control, while an HC-05 Bluetooth module links to a smartphone running a custom app for user interface. 

    More info and Arduino code is available in Soundarapandian’s project write-up.
