Today we assigned jobs and continued prototyping. The scissor group added a leadscrew to help pull both sides in at the same time and made a wooden prototype. It works but might be difficult to make in reality.
The claw group added a stick and practiced picking up tubes. The pink top claw would be actuated and the bottom part is smooth and slightly curved down to allow for the tube to be pushed on and slide off easily.
Finally, the curved grabber method was scrapped and replaced with two wheels that suck in the tube and spit it back out. This method was very successful.
