Re: Chain Driven Telescoping Arm
Team 1251 used a telescoping arm this year, it is pulled out with strap but you can apply the same concept with chain. In every place the strap bends we use UHMW rollers to reduce friction. We used a window motor connected to a pully to pull the strap, overall it works great, it is not as strong as chain but it served the purpose.
I made a quick sketch of how the straping goes. You can also find pictures of the robot here:

I hope this helps, and good luck.
