Hi 

iam working on one of my undergraduate project which is actually related to a mechanical finger . i have designed my project but the most painfull part is  creating a rope  passing through a pipe  should pull the finger

the cable should pull the triangular shaped part in the starting and pass on the red circular surface ( overlapping/concentric) then should pass through the pipe/hose

can any one help me with this problem ..

waiting for ur reply ...

thanks
