For those new to fields like robotics or aerospace, it can seem at first glance that a problem like moving a robot arm or flying an RC airplane might be simple problems to solve. It turns out, however ...

Proportional-integral-derivative (PID) is the most common industrial technology for closed-loop control. A proportional-integral-derivative (PID) controller can be used to control temperature, ...

The ABCs of PID control. Considerations for interfacing elements in the electrical circuit to accomplish those parts of the PID function for position control. Firmware code implementation.

The ability to control the motors’ speed and rotation is the design key of drones, making the electronic speed control (ESC) module an added value and a fundamental part of a drone. In this article, ...

From our very first flight lessons we were taught to check for “full and free correct movement” of flight controls. Every preflight, whether it is for a normal flight or a post-maintenance test flight ...
