Hey everybody, we’ve been building a hybrid claw, but we had a problem where the fork digs into the ground. I attached pictures of it to help.
OK. This picture does not help. It shows a tremendous mess of rubber bands doing nothing. Please clarify the problem.
Raise the lift a bit while driving. Or just move the prongs up a hole.
We had that issue too at first. What you should do is either attach pieces to your robot in a manner such that the arm comes down and hits those pieces and can’t go down any more, keeping the parts that dig into the field above the field surface. Or, as we previously did, you can attach omnis below the claw (use omnis so you don’t have too much friction while turning) and they will keep the claw assembly from scraping the field.
The most reliable solution is creating a hard stop for your arm when it is lowered. The first thing you want to do is figure out exactly how low you can bring your arm without hitting the foam tiles. (You will get the moss accurate results if you do it on actual field tiles). Once you find this position, find a standoff or sturdy piece of metal that will stop the arm at that exact height. This doesn’t require extra programming, doesn’t add too much weight and works reliably for our team. Good luck, and if you have any questions, feel free to ask
