The "grabber" is the mechanism we built to pick up the blocks off the playing field and it is made out of Lego pieces. We've discovered that it isn't the very stable and can break easily, especially if it is jammed. So we are designing some guards to hopefully protect it. We are also securing the connections with nuts and bolts.
Once the grabber picks up a block, it moves to the conveyor which moves the block up to be able to dump into the goal and score. The problem is that the blocks fall off of the conveyor and into the middle of the robot. To solve this, we've designed side panels that will fit on both sides of the conveyor to keep the blocks on. Right now the sides are made of cardboard. But we will make the final versions out of plexiglass.
We are learning that the robot will never be "done." There will always be ways we can improve it!
