Re: Climb Stopping Mechanism
Wait... if you're using a ratchet wrench, could you not just reverse the direction the wrench is ratcheting?

Re: Climb Stopping Mechanism
If you use a ratchet wrench you could clamp the non-ratchet end with a bicycle quick-release lever that can slide in a slot to drop below the wrench when the lever is opened.

Re: Climb Stopping Mechanism
I've been mulling over whether or not it's legal cut the rope to release the robot. It's legal for your robot to damage team provided ropes (G15) as long as it doesn't leave debris on the field, and once the rope has been removed from the Davit it's no longer considered part of the field (R08 blue box).
As far as I can determine, it would not be legal because up to the point where the rope is cut and the robot is released, it's technically a person damaging part of the field (even though that part of the field is legally allowed to be damaged by a robot. Just not anything else). But it was an interesting read through the rules. *Apex Robotics is not planning to release our robot in this fashion. But it did make me curious if it's a quick fix for teams who haven't planned around this* |
Re: Climb Stopping Mechanism
We're using a flex-head ratcheting wrench, i.e. just an ordinary ratcheting wrench except there's a pivot between the head and the handle. In order to lower the robot, we simply undo the velcro strap holding the wrench handle in a constrained position (i.e. between two bolts) and pivot it out of the way. The wrench rotates with the winch as it unspools.

I'll second the comment about marking which side of the wrench needs to be facing out, or which way the switch needs to be flipped if you're using a reversible wrench. Drill it into your pit crew's and drive team's heads. You can never double-check too many times. |

Depending on where it is in the gear reduction and the spool diameter it'll either be completely locked and tough to remove or trivial to remove by hand. |

Re: Climb Stopping Mechanism
After reading all this, maybe it would just be better to climb early and let the robot backdrive as time expires... This seems tricky otherwise.
