Re: Cable/winch vs. chain for telescopic arm
Google "crank up tower" and look at the mechanisms used for antenna towers that use mautiple sections to go from 20 feet to 120. The same basic idea works for robots.
2 years ago we used a simple elevating tower, a 24" stroke 3/4" dia pneumatic piston provided the lifting force, we telescoped 1 x 2 rectangular tubing inside 1.5 x 2.5, using HDPE wafers to keep the inner tube centered. Don |

Re: Cable/winch vs. chain for telescopic arm
Okay... after searching CD-Media for "648" I have found a picture of our robot. I had forgotten that I posted it. Um... you can see the nylon pulleys near the bottom. Unfortunately I don't have a closer picture.
