Classroom Climber plans Help???

I am teaching VEX robotics within my high school classes and throughout the semester I present my classes with different “Engineering Design Challenges”

I want my students to design climber robots and I am wondering if anyone out there has plans for the climbing apparatus. To save cost I would like to make it and have it for many years. Just thought maybe someone has made one already and might have plans or pics with sizes. Also I am open to any other suggestions you may have. In addition I have a great challenge to share called “Zombie Hunter” if anyone is interested I would be happy to share.

Thanks for your time and support.

Mythbusters built one years ago. Here’s some discussion on it.

Haha I love it how the article was “dated” in 2006:

Edit: Looks like all the links are dead so idk if this is very helpful for the OP

Wow, sorry. I didn’t think to test the links.

Here’s the article.
