To Prabhneet, Aurelio, Salvador, Marck, Vijay, and Ms. Fleischer:

Your design for Mr. Helper is the most thorough and well-written of the
designs I received. Your description is clearly outlined, and the section
titles help me quickly find the parts for which I am looking. I really
like that you started your design with a "Mission" statement. A mission
statement helps you make sure your design does the job it is supposed to
do. A mission statement also helps me make suggestions and ask questions
about how it works.

Your robot has a motor on it, but how does it move around? Remember that
there is very little gravity on the space station, so everything floats.
I like that Mr. Helper keeps its tools in a crib. Many robots try to keep
everything connected to the robot, and that makes the robots larger and
heavier. Here are a few things you might think about: How does the robot
know where the tool crib is? How does it know where the docking bay is?
How does the robot take the tools from the crib?

Why did you choose to build the robot out of silicon? How does the battery
get recharged when it runs out of power? Can you think of a way to do that
without the astronaut's help?

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