When IRI is over, I would love to see the CAD for this. having a claw that auto-clamps on contact would be amazing for a lot of appliactions. |
We initially tried using springs but it is a lot easier to add more or subtract tubing runs and preload. If we needed too we were going to adjust it to go faster. We were not supper worried about winning the race as long as we got to it before it got off the step we could pull it and what ever was attached to it back over. Right now its hitting the can so hard it knocks it towards the other side of the field and claw actually tries to bounce off before it gets a chance to close so if we add more energy to the system we will have to find a way to damp out the system so the claw does not bounce off or get it to close faster we have plans to test both just had no time to test it before the event. The claws trajectory actually fallows the rc's handle through the arc that another robot would pull it through in an in the can arm solution. So that means that even if the other robot got there first we would have a shot at catching them and stopping their action, then start winching back. Ill make sure to post the cad as soon as we can. Its actually pretty portable. Perfect for mounting to other robots.. Its fun to hold in your hand and shoot it too. Makes you feel like batman or something. It will grapple anything smaller than the jaws.
