A journey building drones and ROVs and other open hardware and Arduino based stuff
After a very troubled shipping (HobbyKing is great and cheap, but the pain of all these import duties and payments sometimes makes me want to find a EU based reseller) I received all the parts for propulsion compartment of the OpenROV: motors, ESCs and propellers.
As you can see from pictures below the shaft has a small hole on the side for a small hex screw (but not part of the package) and a small hole for a screw on the top. Probably a correctly shaped cap would be needed, but it was not part of the package either. Also the shaft is just long enough for the base of the propeller, but not enough to get to the cone. At this point I really don’t know how I could fix the impeller to the motor’s shaft without it slipping. If you have any suggestions, please feel free to leave a comment.
Together with the motors and ESCs I also received the servo that tilts the electronics chassis: this always impresses me. I know its dimensions (23mm) but I didn’t realize it would have been that small. Look at the picture above, it’s smaller than a USB plug.
Next step is trying to play with an Arduino and try to control the ESCs and the motor from the BeagleBone. And if you have suggestions on how to fix the impeller, my comment form is free for everyone.
