Hey, I'm trying to calculate the point where my robot will tip over but I don't really know where to start. Basically the robot is 24" x 50" and 40" tall. The center of mass is the center of the robot 25" from the ground. Total weight is 44lbs. The robot turns via differential steering so it can turn about its center point. I need to know the maximum rate of acceleration I can turn ( or spin ) the robot before it starts to tip. Any help would be much appreciated.
