Update

During our last class, we have been working on presentations, and three of the subgroups have completed their presentations. However our turn is on the 28th, and we have been finishing up our calculations and CAD drawings on Solid works.  Our team is also contacting sellers for the linear actuators for our design. So far we have gotten the specifications, and we think we have found the right actuators at a reasonable price for our design.  The price so far comes up to about $200 each, for total of 3 linear actuators needed.
