This is a robotic arm equipped with an electromagnet that grasps objects directly from a loading conveyor belt. I designed this project for my university's embedded systems course. The conveyor belt transports a cube featuring a metal piece attached to its surface, and once the arm reaches it, an endstop sensor triggers, halting the belt. Subsequently, the robot activates its electromagnet, secures the cube, and places it into a container. For the robotic arm, I utilized 1501MG servomotors. The electromagnet was constructed from enameled copper wire (reclaimed from an old transformer) wrapped around a substantial metal screw. This assembly is then securely fastened to the plastic component. Furthermore, I integrated an NTC100 temperature sensor into the electromagnet to monitor its thermal activity since it can reach extreme temperatures when in operation (around 3A through a thin wire can dissipate considerable heat). To drive the conveyor belt, I employed a continuous rotation servo with direct mechanical linkage.
