This week we worked on putting the chassiss together as well as the tower that the lift will be connected to. The tower was made from aluminum tubing with one pulley attached to the top. Our first design for the lift were angled pieces, but we decided that having aluminum tubing as the lift would be more reliable. Others worked on the "teeth" design. We made three variations, but it was a challenge to design something that would fit on both sides of the tote. Programmers worked on the mechanum drive code.
