Electromagnetic claw



Having finished an OpenROV as a High school project, I decided to go a step further and attempt o mount a claw on it. I figured that a simple way would be to use a 12v 3w electromagnet to pull two jaws together. A return spring would reopen the jaws. I built prototypes, first out of Legos and then aluminum Tetrix pieces. My problem though is that I have no idea how to hook up an on/off switch for the electromagnet onto the ROV.




Hey Barak,

Did you ever get the claw wired up?


No, due to major setbacks I haven’t yet had a chance to do any testing. Also, I still don’t know how in the world I would wire it.


What version ROV do you have?
