    It's interesting. I like the lead screw open and close mechanism, and I may need to steal that idea in the future. But with a DC motor you don't have position feedback. I suppose you could monitor current usage to detect a stall at either range of motion, or add limit switches.

    'Seems like a very fair price for such a capable gripper. I really wanted to see it crush that Coke can, though.

    Martin: A smart cookie like you could slap in a P5587 sensor on that leadscrew so fast it would make your optical encoder spin. Unless Duane beats you to it and sends me a free sample for suggesting it!

    Several possibilities, but nothing innocent enough to post!

    Gareth on LMR recently made a nice gripper.

    You've got to check out his linear servo made from an old glue stick.

    Ask again when Erco's daughters are about 16. His answer will be more like:

    "I don't know, but I'll tell you what the girl's daddy robot said to the boy robot!"

    I'll refrain from posting a link to the "Marcus Dating Scene" from the movie Bad Boys 2 due to inapppropriate language contained therein. But it's on Youtube and that's my model for how to greet would-be suitors for my twins.
