[Ray Kampmeier] just finished writing some code to allow him to control his robotic arm using force-sensitive hand gestures! He calls it the Robo Marionette. He’s using a MeArm 4 DOF robotic arm, a ...

A temperature-based dual safety system addresses common household risks through intelligent control. Built on an Arduino Uno, it operates in two selectable modes via a slide switch. In one mode, the ...

A clock is by its very nature a device for measuring time, and thus it moves forward at a constant rate. But how about in a ...

In this video I unbox and assemble my very first XFly Alpha 80mm RC jet, now available from HobbyKing. I walk through the packaging, preinstalled control horns, screw together airframe, and the smart ...

Abstract: Diamond turning based on tool servos is gaining applications increasingly in the surface forming of complex-shaped optics. However, current fast/slow tool servo techniques encounter inherent ...

This library allows an Arduino board to control RC (hobby) servo motors. Servos have integrated gears and a shaft that can be precisely controlled. Standard servos allow the shaft to be positioned at ...

int servoPin = 13; // GPIO pin used to connect the servo control (digital out) int servoPin2 = 12; // GPIO pin used to connect the servo control (digital out) int potPin = 36; // GPIO pin used to ...

Stepper motors use a cogged wheel and electromagnets to rotate the wheel one ‘step’ at a time. Each HIGH pulse sent to the A4988 stepper driver energises the coil, attracting the teeth closest to the ...

Abstract: This article proposes a predefined-time synchronization and tracking control strategy for multimotor driving servo systems. First, a mean relative coupling synchronization controller is ...

Running, running, every day, we keep running to work, school, and college. In this busy routine, many of us do not even have enough time to eat… ...
