Hi Mates,
Just initiated the process for a small wall climbing robot. Motor's sensors and control systems are fine with me. Just thinking of the vacum based suction cups and onboard generation of vacum( closed circuit). Any DIY ideas are welcome.

Wondering if a double pump controlled by a 180 degree motion servo would fit the requirment.

Also any idea on the tail for centre of gravity. My proposed robot would be walking in all directions on the wall.
I have tried to source some GEKO material with no success.
