This week we got a lot done. As you can see below we finished building the tetrahedron retriever in solid works. We also did the manual challenge for putting the two tetrahedrons on the tower in less than a minute. Even better than that though, right as the bell was ringing we finished the autonomous tetrahedron challenge with just one class of programming. 
This week we are continuing to work on the claw bot. We have it almost completely built and programmed. We need to build our tetrahedron to do the challenge. We plan to build our tetrahedron out of straws and tape to make it stronger. Our goals for this week is to finish up our bot on solid works and do the first tetrahedron challenge.
