Still working on several designs

We had several projects that we were working on during this meeting, most of them continued from Monday's meeting.  This included both software and hardware projects.

Two of our new team members worked on rewiring and writing a teleop program for the squarebot chassis, which they've been working on for a few weeks.  Currently, the squarebot has nothing mounted on it, but we hope to add some of our mechanisms to the it soon.  The squarebot is designed so we have a space to mount the conveyor belt on the front and something else on the back.

We also continued Monday's projects, the tomahawk and conveyor belt.  We motorized the tomahawk, so now it can not only grab the crate, but also rotate it, the purpose being to keep the crates level as we lift them.  Surprisingly, a servo is strong enough to rotate an empty crate; we still need to test how many balls the crate can have in it and still be rotated.  Our next plan for the tomahawk is to attach it to a rotating arm on the robot.  We also made the conveyor belt the right size to pick up racquetballs, although it still needs to be motorized.  We plan to do this on Monday.

One other thing we worked on was the scissor lift.  We had already built a scissor lift, which we planned to use to lift and stack crates, but it got taken apart.  This meeting, the mentors built a scissor lift out of cardboard, and one of our team members was also building a new metal scissor lift.
