One of our teams has a member who is moving away in December, so they decided to work very hard to have a working linear lift robot in time for a competition on December 6th. Their cascading lift works well and they installed a limit switch to control how high the arm raises.

In this VEX Meeting only one team was present because of it was a abnormal meeting day. That team stabilized their scissor lift; very crucial to a well preforming robot. Screws were also tightened, some keps-nuts replaced with lock-nuts.
Our team is trying to work on our VEX robot more than once a week. We need more time to finish our robot because of unseen problems; too long, too tall, how to attach something, etc. We have both sides of our scissor lift finished although one side is not the mirror of the other...it needs to be adjusted. Our chassis is a U shaped chassis and one side is not the same width as the other so it needs to be fixed. And our scissor lift needs to be mounted on the chassis. Our goal is to be basically finished with our build by Thanksgiving so we can spend December programming and working out bugs. One of our other teams has decided to scrap the cascading linear lift design in favor of building a simpler lift. They are going to build a pivoting arm with a claw. Sometimes simpler is better. Our third team built a prototype cascading linear lift, but the way they had the chain working caused it to break. Also the lift was not very stable. They are modifying the design to use wide c-channels and they have used tank tread to screw the chain to the lift. They are in the process of building their new lift.
Our SeaPerch teams are getting ready for the Middle School competition in January. We have three unique underwater robots that were designed by students.
