PWNAGE 2451 built a telescoping arm for Logomotion in 2011. The link below is the album of our 2011 build season. A lot of good pictures of CAD and the actual robot, especially the arm.

For the wiring throughout the arm we used ribbon cable through the main tubing parts. The ribbon cable was attached to the plastic chain they supply in the KoP that is meant for securing wire to. It keeps things very neat.

I know many teams have also used coiled wire on elevators. I however do not have experience using those.

As far as whether an elevator or telescoping arm is better, it really depends. In 2007, a telescoping arm seemed to be more effective because it helped to have more reach outside the robot frame. In 2011 however, the elevators were more effective because it was easier to control the height and placement of the tubes and a large reach out of the frame wasn't as necessary.


Hope that helps,
