When I said simple and easy, I meant building a ramp to allow another robot to climb up to the platform; if well designed, building such a ramp would be much easier, although I'll admit it may be harder to implement in a match. (Further, it probably would require less weight and power to operate)
My point was that if you awarded, say 4 points for getting onto the platform, the teams that built robots to climb ramps, and robots with ramps, would earn as many points as
two robots capable of lifting themselves, a task far more difficult than building/climbing a ramp.
As for lifting another robot as well as yourself, that would be pretty amazing and would merit recognition
(I only joined 201 in 2008, and the only robot before then I can remember was our Aim High robot, although I think I remember that we used something like a forklift last time we hanged)
