The idea for our climber came from sforbes’ youtube video below.
Since then he has posted another video that is actually closer to what we are really working on.
Here are some of the current sketches of our climbing mechanism.
We are planning for the main central arm to be sheetmetal and for the two rear arms to be round tube with tie rod ends since those members are mostly only experiencing forces in tension.
