From my understanding there was some sort of gas spring that made the climber normally closed so that once it was hooked on, even if the match ended, it would finish scaling. We discussed how to possibly build a climber to do that but we're stuck on exactly how to go about it.

Kevin, you are correct about how 67's climber worked in 2010. I was a sophomore on the team that year and was one of the students who helped prototype it and build it.
Essentially we utilized four 200 lb gas struts (that were held back by a trunk latch we scavenged form GM's test vehicle scrap) that were connected to a rope and pulley system to pull our bot up.
In the match we just had to extend our arm up (while on the bump) and release our servo that held back our grappling hook to hang. One that servo was released, a 6 lb gas strut rotated a secondary arm that held onto the grappling hook by velcro. Once it had almost extended to its full length, a bike cable released the trunk latch causing the gas struts to extend, pull the rope in, and rip the grappling hook off the velcro so it could align with the center of the bot.
Does this help?
