To Drew, Adam, Dawson, and Ms. Betke:

The diagrams you made of Orc are some of the most convincing and thorough
that were submitted. They were the only set of diagrams that actually gave
a full set of three views. When I am on a project, one of the things I
look for in a design is whether it has really been thought out, and if it
is actually going to work. Showing that you have already figured out how
everything is going to fit together builds my confidence that it will work
when you're done.

I have a few questions about the individual parts, and then a few about
the robot as a whole. The arms look like they are four parts with
rotational joints connecting them. With two arms built in that way, can
you pick things up with both arms? Can the arms reach the cargo bay? Do
the arms have hands, grippers, or attachments?

You have propeller fans on four sides of the robot. From physics, I can
tell that the robot can move forward, up, left, right, and combinations of
the four. Is that a problem? If that is how the robot is built, is there
anywhere the robot couldn't go?

What kinds of tasks can your robot carry out? How is your robot powered?
How does it recharge if it runs out of power? If the camera is on top and
can swivel 360 degrees, can the robot see if there are things below it?
When the robot is moving, how does it make sure that it doesn't hit

Feel free to ask us more questions. The best way to solve a problem is to
really understand it. Keep up the good work!
