assuming that the arm is extended 3 ft up and 4 ft out with a relative weight on it of 150 lbs ( perpendicular distance of 5 ft with 3 tetras on it)
even if the previous center of gravity was sitting on the ground the normal force of your robot would be unable to counteract the weight. |
I do not like your assumptions.
(edit: YIKES! That sounded a bit harsher than I wanted. I like Greg. I just didn't like the particular assumptions he put on the problem.
