5. VEX Electromagnet

          TEAMS       4423C  4423D       4502G  4502H                                                                                      VEX Electromagnet   One of the greatest obstacles of vex robotics competition are the size limitations, that’s why many teams design complex deployable mechanisms to expand beyond the limits after the start of the match, however many times is really difficult  to build them without using motors or pneumatics. Instead with a simple programmable command the electromagnet will shut off releasing the mechanism and let gravity or some rubber bands do the rest.   The VEX electromagnet is thought as a new and versatile actuator for many different applications in vex robotics, especially when is necessary to hold different mechanism and release them at a certain time in the simplest way.                                                                Technical Specifications    Compatible with all VEX Microcontrollers and 3-Wire Extension Cables Weight: 43 grams  (Calculated using inventor) Compatible with VEX ARM® Cortex®-based Microcontroller Digital Outputs. Input:            Black: ground            Red: power input            White: control signal Approximated holding force: 20 newtons (2 kg) 3.3 volts supply Attracts any vex steel part
