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 inspired 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!
