Our Group today brainstormed on the various designs on what sort of arm can be used to grab the can from one end and transport it to the other end. Designs included the commonly used pincer, a rotating grabber arm, a fishing hook style arm, a crossbow style arm and a spatula style arm. A lot of ideas were thrown out of the window almost immediately because they were either to difficult to make, too impractical or it is obvious it wouldn't work. For example, the spatula arm wouldn't work as we cannot be sure whether the can will be flung back to the starting line and whether the can will even be flung in the first place. The fishing arm might work, but only if we are very precise with our programming, which probably won't happen. A crossbow arm is definitely out of the question, as it is very difficult to make. In the end, we had two left: the pincer and the rotating grabber arm, which are very simple to make and easy to program to grab the can.
