Last Thursday while doing a demo at our school we became bored with just picking up tetras and placing them on our one goal, so we tried out picking up other objects that we had handy.
As it turns out our large bulky tetra manipulator is the perfect size for picking up trash cans by their handle and moving them about.
From this we continued onto chairs, along with coming up with challenges, like balancing a chair on top the trashcan we set on a table, then proceeding to place a tetra on top the chair. Next we actually picked up our center goal and placed it on a table, then proceeded to place two tetras on top the goal, which is the highest we had ever tried stacking.
Needless to say we all had fun and the demo was a great success at giving the community a glimpse into both FIRST Robotics and FLL.
