Here is a way two robots working together could score 40 points legally, relatively easily.

Robot A: Flat top 8" off the ground with a ramp.
Robot B: Vertical arm with hook on top, extendible to 83 inches (max height is 84 inches)

1) Both robots drive into pyramid.
2) Robot B drives on top of robot A.
3) Robot A drives to center of pyramid.
4) Robot B extends arm 25 inches (25+8=33)
5) Robot A drives so robot B's arm taps zone 1 bar.
6) Robot A drives to center of pyramid.
7) Robot B extends arm 55 inches (55+8=63)
8) Robot A drives so robot B's arm taps zone 2 bar.
9) Robot A drives to center of pyramid.
10) Robot B extends arm 83 inches (83+8=91)
11) Robot A drives so robot A's arm hooks onto zone 3 bar.
12) Robot B retracts arm (or activates winch) and raises itself straight up into zone 3 for 30 points.

This sequence follows the rules for climbing the pyramid precisely, robot B contacting each level sequentially and never contacting more than two levels at once.

For even more scoring goodness, robot A then raises an arm, hooks the zone 1 bar and lifts off the floor for another 10 points.
