Control a robotic arm with the PCA9685 Servo Driver using Arduino Mega. The arm has multiple servos for the claw, wrist, elbow, shoulder, and base, allowing movements like 360° rotation and 0°-180° ...

I was looking at the electronics behind the little Petoi dog robot (right), and noticed a chip I was not aware of before, NXP’s PCA9685. On a deeper delve, I noticed Adafruit also uses it for creating ...

Maker Michael Klements has built a unique electromechanical clock using a little Arduino hardware, code, and 28 servos, which tilt panels to reveal the correct time in digital format. As the time ...

Abstract: Versatile and low-cost four-legged robots have been developed to solve surveillance problems in harsh environments. This compact platform utilises the computing power of Raspberry Pi 4 to ...
