We do have a half-baked plan to flip totes using an extra piece of aluminum angle attached below our lift so that it can touch the floor and get under the end of a tote. If we find out this doesn't work (or knocks too much stuff off the step onto the other side of the field) and we still have time to develop an alternative before stop build (doesn't seem likely at this point), there's a plan B. We have a conceptual design for a flipper that uses two pneumatic cylinders and some downward-pointing grippers located on the back of our robot. One cylinder pulls the totes toward the robot; the other cylinder lowers the gripper into the grips on the sides of the tote before pulling it in, then lifts the side to rotate it after it's close and personal and away from the step. The "pull" cylinder then "pushes" the now-top of the tote out to complete the flip.
